Hey all,
I have been considering putting a slighty built 454 into my 69 camaro (425 hp, 500 tq). Would I need to replace my 12 bolt rear? If so, what rear end and gearing (streetable, but also for the occational track run) would you all recommend , and what tranny?
Also, what kind of qm times should I expect to run?
Thanks for the help!

 

Heck no you don't need to replace it!

TH400 trans, even a 350 would be up to the challenge. Maybe a 3.50 gear with that kind or torque, getting your car moving won;t be a problem. Keeping your gas tank full will be the challenge.

 

Thanks for the reply, the 454 I'm talking about is a crate motor... what do you think it would run in the qm?

 

Way to many variables to be guessing 1/4 times. Seen bb's run 14's all the way to the 7's.

But if I had to, I would say 13's.

 

Do you all know any reliable companies to buy crate motors from?
I don't have much time so i have been thinking about doing that...the possiblilty of putting a 454 on a stand and building it is still an option though.

 

How much money are you wanting to spend? GM has a crate 454 for about $4600 I believe. Or you could spend a bit more and go for the 502.

 

under 5K for the engine.

 

if your gonna spend 5 G's mightest well go the extra 2 and get yourself a 502.... man i know someone with a 502 in a 72 chevelle and

 

Zoomin I see that you have 2003 Z06 and a 69 Camaro bbc. So which do you like the most? I was about to trade my 69 Camaro in on a Z06 but changed my mind when I found the problem and fixed it.

I'd like to have a Z06 one day...I really love my camaro but there just is nothing on the market (aftermarket parts) that can make a 30+year old car into a cadillac like the Z06. I'd like the cold ac, reliability, and handling of the Z, but there is no replacement for the displacement in my camaro.

 

I woundnt buy any crate motor. Build one yourself cheaper and you can put what you want in it.

 

What he ^ said

 

Thanks for the help guys. I'm going to build it myself instead of the crate. =)

 

To bad, if I was going to do it, I'd put the 572ci(720hp) BB in it.

 

that would be nice. but unfortunatly i'm not made of money

 

A lot of people build these radical combos...but forget how hard it is on a car that is not properly setup. Blow your tranny, your rear, your doors do not line up any more....etc....
