ive been working on this truck now for a few months and getting close to having it running. just wondering if someone can give me a rough estimate on the horse power and torque numbers it should have.

starting out.

the motor is a 1972 Chrysler 400 big block
punched out .030 to make it about a 408
cam with .484" lift and 280 degree
750 edelbrock
offenhouser dual plane intake
full tube headers
dual 3'' exhaust
i believe the guy before me had the heads decked slightly.
8mm plug wires

it has a brand new rebuilt 727 behind it and it is sitting in a 89 d-100 stepside.

ill post up some pics later on.

just looking for about a ball park estimate of what it should do.

 

engines are not my thing. BUT when i look at the cam carb so on. ill guess 380-390 hp. has to be above 360. with that cam it wont be a daily driver. i based my idea on the fact that i had a 1965 chryster 300 L, 413 ci a lot like your 400ci. my 413 had a cam 268 degrees advertised NOT at .05 with .430 lift. this was the 300 cam made 360 hp. the new yorker cam was 248 degree .389 lift put out 340 hp. my 300 L got the same mpg as a new yorker. but would out run it. you might talk to a good cam maker
