Question What to do with my 454?

I have a 71 corvette with a 454. I am going to do an engine rebuild. I am trying to see what is the best way to go. It used to be raced but it appears to be mostly stock. I want to make the car a pretty nice street rod but don't want to go full out. I don't know yet if it will need to be bored over, but if it does it would only be 30 over as the engine has low mileage. What should I do as far as pistons, heads, intake, and carb? Is there a better manufacturer to use? I am really looking for which way to go and whom to use, without spending an entire fortune. Any help would be great. Thanks, Penguin

i've never had one 'cept in my dreams, but i think if it has low miles i'd leave the short block alone. maybe even the heads. don't know good from bad ones tho. a cam, intake and carb should do it, and headers. somebody out there will help you out.

Just hadda nother thought, they detuned the engines in 71. Find something that tells you the cam grind of the hottest output 454 for the 1970 model year and get that, as well as alum. intake, bigger carb and headers. cant lose.

Hi,
Why do you need to rebuild? something wrong? The vettes get the good motor of the year, you would want to keep it numbers matching if you can. (check your head and Block number on google search)
Go for the stock rebuild kit, you do not need any fancy pistons etc.. Take your Carb to your local shop for a performance rebuild, the stock Rochester or Holley you have will be just fine when done right.

look into a Edlebrook RPM manifolds and matching cam. Not the wildest combo, but work very effeciently together.

The best way to do it is look around at machine shop/garages in your county or town and find the single sweetest looking early 70's GMC truck. Get that shop to build you a stock 454 for your vette. And I hope it's a crazy-heavy gold-flake painted car or something.
