Or just put a good LS in it. :D

Are Allan and Andy Acronym having fun yet?

LS's are for street driven gas savers :unibrow:

I like driving with something in it I could beat on like a red headed step child :lol:

Good motor for the wife's SUV grocery getter. :D

But they don't just sound as good as your and Greg's Mustangs. :unibrow:

sh*t bit the bullet call nelson

he'd be biting more than a bullet if he called Nelson. LOL

You should be banned, beaten, drug behing an old Dodge diesel on a lumpy Iowa gravel road for that response.

Nothing personal. :lol:

He wants a fast car not a big dyno # and burnout session.

Agreed.

On the other hand, it surprised me how good some of the previous gen F-bodies sound with a GMMG catback.

No motor mods just exhaust.

Lets not forget he wants it done within this year. :D

Guess that hit a few nerves! Hell I thought it was funny. Go with someone local. It's nice to be close if and when something comes up.

I copied this link from an e-mail Jerdog sent to me that I thought was pretty interesting. Also, upon more research i have found that many engine builders have been complaining about how loose the chains have been fitting lately as opposed to years ago. I remember when I was putting timing chains on back in the day they were always very tight. Apparently that hasn't been the case as of late.

This is a pic of the Hy-Vo chain used in the NASCAR engines that are not running belt drives. I am currently trying to see if they make one for Chevy applications.http://image.circletrack.com/f/26295...hain_setup.jpg

Good stuff. I am waiting to see what you decide to use. :unibrow: I'm gonna ask Watson Racing what they recommend and use next time I'm there too.

That is something I was talking about with a local engine builder. I have been thinking of using a high end gear drive and he said a good roller "comp" or belt drive "jesel" I just don't feel like I can trust a chain with all differences in stretch and balance. Still undecided I like the high end gear drive units.

Another option would be this belt drive system. I like the xceldyne because you can get it with a dust cover.

I talked to my engine builder about gear drive and he said the dog bone style were unreliable. He told me that the most reliable gear drive set up would be one that had the center gear integrated with the timing cover. I dont remember who he said makes it though.

Man, are we gonna end up with belt drives? :willy:

Found this quick and to the point article.

I was thinking Summers Brothers

Another option

Summers Brothers

http://www.summersbrothersracing.com...t%20drives.htm

Gear Drives,,,
N/A engine - you dont want them in a N/A car because they transfer too many harmonics to the valve train, basically too sturdy and can cause issues

Blown engine - gear drive is good to use here due to the force they see. the thing that will allow a blown engine to work good with these are the have a large blower belt coming off the crankshaft so this makes a gear drive perfect here

Timing Chains,,,
N/A engine - good for use on any N/A or NOS engine with normal spring pressure for roller cams (600-650max open IMO) or any flat tappet engine. Drag race or circle track

RPM means little to nothing with timing chains until spring pressure goes up. Racers running camshafts that are very aggressive (not something a bracket racer/street guy would run, more like a Super Stock or Comp camshaft) that need say 800 pounds open and are pushing the valve train to the limit will be trying to retard the camshaft the way it wears the camshaft gear teeth so this is when a belt drive comes in to play here

If your not running that sort of aggressive lobe/rocker combo with high spring pressure it really doesnt make a huge difference which one you go with, more so which one you can afford.

You can set thrust easier and degree the cam easier with the belt drive.

If you use a timing chain you need to use the SA Gear Billet with the 2 piece adjustable cam gear (like a belt drive) or the Cloyes 9 key way set or the Cloyes unit with the adjustable cam gear. I would not use a timing chain that is not billet, they seem to allow the chain to fit better

SA Gear the chain fits tighter and stays tighter which are many Comp, Lunati and Erson timing sets.

OK here is my experiance with all three
over the years i have used and seen all three devices
i have put gear drives in engines that were used in dirt track , street and drag and have never had a failure as of yet , i know it happens but it has not happened as of yet with the stuff i have seen i think they work well , if these things can live 5 seasons in a late model dirt car then i assure you they will last in a drag race application

timing chains- have used over the years with equal good luck , but have seen them stretch with very little use in high rpm motors, but yes they have come a long way in the last few years and if you are on a budget then they are the way to go

belt drives - i use a jesel on my stuff as i like the fact i can degree in the cam easier and can adjust for ****y track conditions if i need to and i do believe that they help with harmonics when you start getting into the higher RPM range and the timing seems more stable

but let me add this---why would you put a 70 dollar timing chain on a 10-25 thousand dollar engine just does not seem right but i guess that is just me ,kind of like using a 29 dollar oil pump on a motor you pay big dollars for--will it work, yes but i just can not see the point in doing it
but to each their own

Yes used alot in sprint cars

$1070 at Summit

I also read that SA makes PBM.

I'm swaying toward belt drive right now but i'll need to do more research. Accesability and adjustability make the belt drive desirable. If the belt drives can handle high cylinder pressures and 14:1 compression it may be the better choice.
The Summers Brothers option is pretty interestng also.

The only thing I dont like about the Comp belt drive is they dont have a dust cover option.

Good to know, and I know alot of sprint cars are using the PBM aluminum blocks so I like this option.

guys guys guys, chains are fine, the end of the world is not coming....well if it is i'll see you in hell. LOL

Cloyes & SA make the high end timing gears for many different timing sets that are sold by other Co's. ie Summit, Manley. Lunati, Crane, Comp & Jegs etc.. It comes down to what brand chain these other Co's decided to use with their sets



.A belt drive will be more precise with timing and take out end play in the cam and hermonics in the valve train. It is also nice to be able to change cam timing without pulling the timing cover.

I do agree with Vince..A good timing chain set will be more then enough for your application G


On a side note I read that the PBM alum block is made in New Zealand

I think the cam thrusting forward at higher rpms contributed to the chain failure. If checking the chain for wear is going on the maintenance list wouldn't it be smarter to go belt drive?

I was just thinking the same thing! :willy:


And the PMB iron block is no longer made in Asia. :D

In addition cam end play will be easier to fine tune.

Yes it would be smarter. Most say a chain will stretch faster then a belt but a belt does have a shorter life span I changed my Jesel after 3 seasons and it was still tight But I don't take chances I was more worried with it being dried out

IMOHO I'd stay clear of a gear drive

This with a Hex-adjust True Roller set up and you should be good.
http://www.cloyes.com/Portals/10/Ima...ton_Large2.jpg

Don't forget Jesel

Really? I didn't know that, where are they made now a days? Thanks.

Danny Bee belt drives are pretty slick also. The ease of adjustability is pretty sweet. You can even have a slightly different timing spec for specific tracks if you want. I'm not sure on the SBC but on the FE Danny Bee set up the belt is in plain view and can be checked periodically. None of them are less than $1k so it is a big leap from a quality chain in price for sure.:rolleyes:

I've looked into them just haven't justified the cost yet. Yet:D

Isn't smarter what we strive for every day? :lol:

I figured it was a no brainer. :unibrow:
