I am going to have to go back and look at your build again for some ideas. I plan to fire the sub into the back seat as well. The shape of the trunk makes it interesting, that's for sure. Definitely need to leave that to a pro.

audio stuff is actually what spring boarded me into being a car junkie.lol before i could even drive i was working on car stereos and sitting in cars bumping the stereo in the garage lol.
I have done sub installs in a few years but i will tell you that bass is not like treble and you dont hear bass but feeling and bass frequences are actually louder the farther they are away... basically what im saying is that you dont what the sub facing the back seat, you want it facing towards the back of thbe car and the bass frequencewill bounce off the truck wall and will create a much louder "sound" at lower volume levels which in return will give you a much better sound quality whick imo is the most important.
i dont know what the factory kick look like, are they built for speakers or are you just gonna cut holes for them?
if you can get some custom ones make for not to much i would really go that route cause it helps alot with sound stageing if the speakers point towards the listeners ears and not right into thier foot.lol
if you need any help just give me a call im no pro and a little rusty but for the most part know my audio ****.

I have heard that it is best to fire them to the rear
 

but I was trying to keep my car quite as I could inside. I have dual 3 inch exhaust with an H pipe. The mufflers are 14 inches long and you can see straight through them. I knew I was not putting sound deadening in the trunk or carpet, so I put a thin piece of metal over the back and cut a hole for the sub to fire through. That way I could isolate the trunk from the cabin.

My sub box is very simple. basically a square with an angle to match the angle of the back seat. Mounted my amp to the box.

I have pics of what it looks like inside the car
 

but they are too big to post. If you like I could email them to you

I was thinking something very similar. :thumbsup:

Hi Todd
Are you going to have it done for the Lateral get together???
Mario

Done....probably not. I am hoping to have it complete minus the backseat, subwoofer box, and carpet int the trunk. The car will be there more than likely.

I need my car back on the road by next weekend for some cruises and Sema stuff. I now have the Heat/AC unit brackets and misc. to get it level and in the right position for ducts and hoses. With a shaved firewall and not wanting to breach it, things are more difficult.
I decided I wanted the combination of old school fresh air vents and modern AC and Heat. I have good memories of opening the vents in my 68 on a cool night. So it will have both. I installed the 4" JL's in the kicks and isulated the area behind the speakers.
Since the dash top was replaced by Prodigy Customs during the body restoration, the defrost vent mounts were missing. I fabbed up some brackets out of some roofing materials and they are exactly where they need to be.

I spent a **** load of time on the rear dash shelf getting it to fit decent. I trimmed the edges with molding. I also insulated it with the same material used on the floor. The JL 6x9's are in and it looks decent. I need some more molding to put in the cut outs for the roll bar. All and all not the proudest moment of the build but I think it's good enough.

Looks good to me!:thumbsup:

The rest of the day was spent on misc. wiring including the AC, convenience lights, stereo, and cutting the carpeting. At the end of the day it was cool to have the interior lights working with the jamb switches and playing King George off the ipod through the front speakers. :thumbsup:
Tomorrow I'll install the kicks for the final time, run all the amp wiring including rca cables, intall the carpet for good, shifter boot, radio, cut the holes in the firewall for the AC and heater hoses.

Nice progress! I look forward to checking it out soon!!

Well I decided that I have done enough work on my car lately. It's not finished but getting pretty damn close. When you garage looks like this, it's time to throw the seats back in and enjoy the fruits of your labor. I like driving it more than working on it anyway. I am a crew of one and this is the time to drive my car. It's comfy now and I have tunes. In the next few weeks I'll have a box built, carpet the trunk, and put in the back seat. My main goal was get it decent for the Sema fun.
http://i200.photobucket.com/albums/a...9/IMG_1162.jpg

Carpet is in, radio is in, all speaker wiring is routed, shifter boot, kick panels, rear shelf, all speakers except sub. Sticking point if drivers door panel. The door won't shut with it installed in the right spot for the windlace. Car is identical on both sides. Probably going to need to shave the panel. So may end up recovering both panels and then the rear panels will match so they aren't done.

I decided to clean up the garage and in the middle put the front spoiler on with one bolt. What do you think? With or without the spoiler?

I took the car out last night and today. What a huuuuuuge difference the second layer of insulation and carpet made. The floor doesn't get even warm and the old school astro venitlation is awesome. It's much quieter as well.


I will be at the Lateral G dinner and hopefully the road races. A shameless photo.
http://i200.photobucket.com/albums/a...9/IMG_1175.jpg

You will have to see the interior at the Lateral G party or when it's finished. Now for the best part, it's time to take the car out. 75, no wind, and not a cloud in the sky.

The car looks great. I say keep the front spoiler on. I still can't get over how large that rear lip is, simply awesome.

Damn that sucker is sharp! Definitely with the spoiler is my vote. :thumbsup:

wow im surprised how much differnt the spoiler actually makes!!!
now go get some more bolts and put it on for good!!!
and if you dont use the braces dont plan to go over 130mph lol

Keep the front spoiler :thumbsup:

Definitely going on :yes:

Spoiler looks good...it's a keeper.

I'll give you a call tomorrow. Sounds like we have the same plan for Saturday. I say we roll together in style. Looks to be my last weekend with the car so I'd like to make it count!!

There is a car show Saturday morning in Henderson I have been invited to, you should come along. Give me a call.

Spoiler! :yes:

Spoiler.

I ran mine for a while without the spoiler
 

I like it on there much better and on yours as well. Makes it seem lower in the front.

I love your wheels. Are those DPE's or Forgelines, I cannot remember

ZE Boost by Boze...I love em too:cheers:

Wow man, the car looks sick! I'd 100% put that spoiler on there. :thumbsup:

It's on for good:unibrow: Work ....what's that.

Well the transmission is coming back out of my car. I have been fighting a vibration at highway speed in approx 85-95mph range. There has always been a vibration in the 2600-2800 rpm range in the motor. Wouldn't call it a bad vibration. In fact I rode passenger a few days ago and really didn't notice it around town. Just thought it was solid mounts/body mounts. In 1-4th gear it's really not that big a deal. In 5th more harmonics are transferred and it stays in the pocket longer. Orginally I thought it was pinion angle. Until I pushed in the clutch in the pocket and it went away. I was also able to go through that mph range in 4th and beyond with normal vibration.

When I had the engine built it went beyond schedule and they were impossible to reach for a couple months. They were supposed to send the flywheel I paid for. It didn't show and I couldn't wait. After a ton of research and talking with the engine builder. I have a gen vi block with a gen iV crankshaft. I assumed since they used a gen vi block that was the proper flywheel. Turns out you can use a gen iv crank with a adapter for the rear main seal. Keep in mind this is an external balance engine. After some research it appears the weight is in a slightly different place and the imbalance is 33 OZ in the gen iv and 41.7 in the gen v/vi. 8 oz is quite a bit a weight on the end of a crankshaft. I am surprised it only showed up between 2600-2800. I hope I haven't done any damage to my engine. :rolleyes: Would have been nice for them to put something in my paperwork indicating this little fact!!! Oh well....time will tell.

See the difference?

any reason with all your engine work done, your builder did not internally balance the motor? on the 496 i built for vinny, it balanced very easy with taking weight out.
hope everything's ok

That is exactly what I was trying to explian. They are a few grams different and different location. Hope this fixes you, it sounded like it was a few grams out. I doubt you hurt the motor though.

Car looked killer BTW, Appreciate you bring it out to the party. People we GaGa over it. But I missed that ride.

Next Year!

I don't know why they external balance the 489. In my research most of the cast cranks are external balance in 4.25 stroke. I assume it's much easier to just balance the bob weights and use external balanced flywheel/balancer. I am very impressed with the engine as far as performance goes. I caught them during some growing pains and now paying the price for it. The rear main seal also has a small drip. I might as well dig in while I'm there. Now that I know it's two peice I get to pull the oil pan as well. :censored:

Frank...you are correct that mcleod makes a separate flywheel for Gen VI 454 and 502. Mcleod said the counter balance weight is the same but the placement is slightly different. I never dreamed I had a gen iv crank in this motor. Thanks for the words about the car.

i used scat 4130 crank and h beam end cap screw rods, 4.250 crank, 6.385 rod with wiseco forged piston.
the crank i got was external balance as well but there was a certain part number that was almost always too heavy and not light as its way cheaper to take weight out, then ass it.
hopefully you don't have any issues, the rear main will be fun enough. goodluck

Three hours later and it's all apart. Probably a half hour on a hoist.:rolleyes:

Anyway here we go.

This is an interesting picture and what I believe to be the reason the improper flywheel didn't vibrate anywhere but that specific rpm range. The centerforce weights were definitely compensating.
http://i200.photobucket.com/albums/a...9/IMG_1212.jpg

The inside of the bellhousing has a ring around the inside. This is definitely throw out bearing grease.
http://i200.photobucket.com/albums/a...9/IMG_1210.jpg

The clutch, flywheel, and pressure plate couldn't look better. No oil penetration.
http://i200.photobucket.com/albums/a...9/IMG_1229.jpg
http://i200.photobucket.com/albums/a...9/IMG_1230.jpg

After three days of crawling around on the garage floor, I got it back together. I went with the proper gen iv centerforce billet steel flywheel. Nice piece. Of course I then had to remove the shims from my starter nose due to about .060 difference in nose to ring gear clearance difference from gen iv to vi. I did buy a real metal clutch alignment tool for like 20 bucks. The tranny went in so easy. I had it up and in in less than 10 minutes. Best 20 bucks I ever spent.
http://i200.photobucket.com/albums/a...9/IMG_1232.jpg

Well, it's smoother everywhere. But......I still have a vibration. Now it's only at 2800 rpm. Man is she a sweetheart everywhere else. I tried to feel a weight on the balancer but couldn't get my fingers in there. Next I need to verify it's got the correct balancer.

It gave me a chance to clean the bottom while I was under there. Changed the oil and it looked great, changed the tranny fluid and it looked fine as well. Seems things are breaking in nicely. Here are some photos of the bottom. Don't think I have posted many.

The guys at ATS did a fantastic job on my exhaust. Fits so nice and snug. Never has it touched anything in the road.

Still looks fairly clean....better get a few more miles on that sucker. :D

Looks good under there man!

Hi Todd those headers firt very nice tucked way up. How did you make out with the interior guy?
