Ok, engine opinions....
 

So I made the deal on the '71 Camaro. I'm having some work done by the guy that built it before I pick it up. Now I'm thinking, should I keep the 406 in it or put a 502 in it or a hopped up small block? I called the Shafiroff and talked to a guy about their 540/695 hp motor. He went through all the specs and after he told me that it had a big solid roller, I had some second thoughts. I really didn't want a solid roller street car. I need to make a decision in the next few days if I want to get this done. What do you guys think?

SW

Well I think that you should get a big block
and then sell the 406 to ME!

What are your intentions for the car?

I might do the power tour with it, run it at Pigeon Forge ect. I don't really want/ need a fuel injected motor since most of my other cars are. I need to decide if I want lighter weight for handling or big block power..

SW

Hmm, I was going to tell you to skip the Camaro since you already have the same platform with the TA and buy a Cuda or Challenger. ;)

But now that it's yours, I would maybe do a nice all aluminum SB2 or alum 454 small block? You already have a big block in the 69 Camaro.

I say de-stroke it to a 377 and rev it to hell and back. It'll make good power, and be a blast on a race track.

I was thinking about that, but this car just showed up..:) I might do a Cuda next.

SW

Aluminum big block. All the fun at half the calories. Just my 2 cents.Good luck.

sw

nice purchase...very nice and clean car...
i like the suggestion of an sb2 small block ..now that would be different and make gobs of power.....
i think you would enjoy the car more with the lighter motor and more useable horespower...im not in favor of the big block....
enjoy the new addition


radrambler

You could put a carbeurated LS2 that will make about 550hp. Simple, no electronics.

SW, you da man.

An all aluminum 540.

Now that is some serious power potential. :thumbsup:

You are just plain sick.......sick in a killer way....dad?

Yea, run the MSD set up and a carb on an LS motor and roll man roll!! Just don't put a sissy automatic in it.:D

I would think you are close to being broke! Sooner or later it's got to happen. Too many cars.... That or the wife is going to kill you. Either way not much time left.:lol:

Leave what you have in it. I do hope you are going to enhance the car with a new set of rims though.

R.P.

454 SB is a good option...as is an aluminum BB.

The main question, as was asked, what are your intentions?
I like them to hear me coming...BB:unibrow:

572 HP 505 TQ from my carbed Wegner Motorsports LS2 complete with slick CNC'd accessory drive and valve covers, PS pump, alternator and compressor.

Runs like the 12.5:1 LS7 big block I took out but without the weight.

In this thread before the FM5's are on the car :D

Nice looking car man, i'm close, sometime i wanna check out this collection! I'm just in San Antonio now...

I'm lucky, my wife loves cars too, I just my have to get her to get a job to support my habit!

I understand what you guys are saying about a SB2 motor, but I have a few high tech cars and want this car to another old school ride. I learned how to autocross in a '76 T/A in highschool. I want to make this car handle and I'm leaning towards a hot small block, maybe 427..

thanks again,

SW

William, stop by anytime!

Hey SW,

You might want to take a look here then!

And congrats on the new toy.

sw, how about a blue flame 6. but first fix the rust. lol

We just did a 69 Camaro with a blown 541 engine with over 850HP and its insaine but I think the cars are so much better to drive with a worked LS1-LS2_LS7, you can get 700HP out of the small block on pump gas and people will not believe that you have that kind of power in a small engine. We are building another 69 Camaro right now with a built LS1 and twin turbo that will kill any big block on the road for the most part. I can send you some pics if you email me. So over all and for effect go big block if you want raw power but if you want to blow peoples minds go small block built up it will get much more attention and handle better because of the weight.

what if you were stumble accross a killer deal on an sb2.2 topend? i just happen to have one set left collecting dust:unibrow:

I say Gen III. GREAT power, and balance

Yes, you have explained that before. She must be one heck of a good samaritan.

I am with Scott, all aluminum 540. complete motor 425LBS, so it is light, and serious power potential. With a baby 114 LC smooth idleing 255 cam, only 630 lift, with little bitty 310CC heads, we made 684HP at 6400RPMs and started the pull at 3000RPMs and was 610 torque and held over 600 the entire pull. And those are not big numbers for a 540CI. With a set of AFR and a nice hydraulic roller, you can see 700 docale horsepower you can drive. Coming from someone that knows a thing or two about hard chargeing pump gas small blocks (my street racer goes mid 10s on motor at full weight, I can also tell you to make that power it has some serious camshaft in it. The differnce in Michaels 540 and my 404 is night and day for driveabilty. My 400 sounds like somehitng is wrong with it cruising around and it does not clear out to 4000RPMS, LOL! the 540 purrs at 2000 in overdrive.

I'll have to take you up on that "stop by anytime" offer. Maybe in a few weeks when it starts warming up. I'm in SA till August sometime so i'll be around. I've seen your car a few times at TWS and seen you walk by but was always in a rush to get back on corner.

William

How about you sell me that weak 427 you have and put your new TT motor in early..:D

This car is not a car I built from scratch like the others, I just thought, while he's got it apart, I might as well upgrade the motor. I would have to get another subframe or modify the stock one to accept a LS series motor. I really need to decide if I want to go BB or SB..


fesler, you have built some killer cars and I understand where your coming from, but your cars are in a different league than my '71. Here is a picture of my 1400hp hot rod, it's insane..

thanks everybody for your input,

SW fill us in with more pics of the:wow: TT v10 pleeeez

GM performance crate engine. 502/502 got one in a '70 Camaro that I bracket race. Shift at 5600. This engine is like an anvil. I think it is around 570 ft. lbs

Less is more

Based on what you've got in your collection, I'd say you need an aluminum 632 cid bbc, 1150 dominator.

...i like the sound of that. (not to mention how it would sound!)

:yes:

3200 lbs with me in it, pump premium, 36 degrees timing, 10 second quarters all day long in good air. Ain't touched it since I put it in about 7 years ago.

So at that rate...you might want to reconsider your signature!!!

Sorry, couldn't help it!:lol:

Lead.

Thanks for all the advice guys. I'm getting a 496ci BB built by Pacific Performance in Anaheim, Ca. It will spin 6500 and make 650-660hp about the same torque. It's not a "crate" motor, they are building it from scratch with good pieces. The guy I talked to, Troy, was very nice and knew his products. He didn't just try and sell me what he had on the shelf.

SW

Good one. Different car. My L88 Camaro I've had since High School/1973. Its a clone kinda but Chevrolet never built one I don't think. ZL/1 was there max effort Camaro IMHO. I looked at those blocks when I built the L/88 and didn't like them. Used Vega liner technology or something like that. Also not very strong. Plus they wanted ALOT more money. I looked at the Reynolds block but that was not GM.

You are not alone. We've got a 496 built for Jake Parrott's project.

cool, check out chevelles.com for some great combos
i went 11-1 496
scat 4340 crank, scat h beam 6.385 rods, wiseco pistons
afr 315 cnc heads, ultradyne 4/7 swap cam, .711, 262,266 dur @.50, solid roller
dart intake, pro systems hp1000 built carb
canton road race modified pan
been ready to dyno for months, should be 660-680
goodluck

If the dyno is honest, $50 says its more like 620-640HP :yes: Which is plenty. Homie.
