I need some 454 help.
I posted this over on Tech is the BBC forums but haven't had any luck on some answers.
I've been looking all over the net for the HP/TQ specs of a 454 from a 1978 1 ton truck and can't find a thing. Anyone know these numbers? Also, what would be a good combination of parts to make 450RWHP N/A out of this engine? Any help at all is greatly appreciated because I'm clueless..

heads, intake, carb, cam and headers.
that engine should be about 300hp/375 tq.
it probably has peanut port heads, which are small round ports[good for low end torque] but the biggest obstacle for performance improvement.
there is tons of stuff out there for that engine but unless your put a blower on it
you should change the heads, i can't give you a detailed list but you need square port heads with about 260-290cc intake runners, intake to match, 750 carb and maybe cam and exhaust
whipple makes an easy to install blower for those stock engines, ati probably too.

Great info, thanks for the help. I'm hoping the motor goes in a 68 Firebird, but not 100% on that yet. I'd like to use a TH350, but I'll have to look into what kind of power they can hold when built. And yeah, the plan is to run a GM 12 bolt. I want this to be as streetable as possible while putting down those numbers, because it's going to be a street/strip car.
I may throw something around a 100-150 shot on it afterwards if I'm not happy on the times it puts down. I guess budget isn't really an issue because this build will take a while and I'll just be spending as I go. If you need to know anything else just ask, and thanks again for the help.
