Stocker engine choice

Dave Borror · 07-31-2011, 06:19 PM

I'm in the process of building a stocker from a 71 Caprice.This car came with the 400 SB. Natural class would be O/SA. The Since the Caprice came with the 400sb,402bb,and the 454.I like all the choices but the 402. Next question is, the Impala came with the 350 which would give it the Hp break and put it in I believe QorR/SA which puts it with the 95 era 350lt Caprice.which is about .5 difference on the index.and I dont see it running with the fi cars.I dont expect to tear the index but would at least like to be -.5 under.This car has been a very winning bracket car but with a 383 in it.I've race Stock for years back in the 80s and like the odd ball stuff.Give me a little input on which combo you would start with and why.Thanks Dave

The 350....Natural N add weight to O....the 400 is a 2bbl

Dave Borror · 07-31-2011, 08:34 PM

yea I know just was wondering what you guys thought on which motor and why.

greg fulk · 07-31-2011, 08:53 PM

400 with 2bbl would be a bad deal. I think the 71 350 @ 270 in your car is the lowest rated Hp of any Chevy 350 4bbl. The 487 heads are a pretty good head everything else is normal 350 stuff. I'm not sure on the pistons in that engine though.

Change the tail lights and 350 2 barrel 993 heads - Q/SA
400 is HORRIBLE

Run it in O with the 350/ 4 bbl . Easier to start there.

Richard Grant · 07-31-2011, 11:09 PM

The 350/4 barrel would be fairly inexpensive to build and fairly easy to make it go .5 under. Built right it could go 1.0 or more under.

Thanks Guys for emails and replys. Going 454

I don't know who's been writing you, but that is about the worst choice you could make.
If you want me to elaborate, write ME.

Mark,PM sent,also the 350 change to Impala from Caprice,and 454 were my two choices, the 454 for the TQ .Guys give me some pros and cons of the two. I always ran sb cars. but nothing with the weight of the 71 B Body.HELP with reasoning,Thanks Dave
