Hey Gang - Need to know what is the best way to get 400 to 500 HP out of this 400 small block I have picked up with the original crank. I have read alot of forums and likes & dislikes are 50/50. It seems like I ned 5.7 rods for sure but not sure on the type of heads that are going to be needed?? Any information would be great & I like the details & my budget is around $5000.00.
how about 10 to 1 compression ratio.vortec heads with cut down valve guides. 1.75 inch tube headers. 360 degree single plane intake.1,000 cfm holley annular discharge carb.hydraulic roller cam,say something like COMP #12-602-8. 243-257 degree duration at 50. 0.533-0.519 valve lift. 107 degree LSA. lots of torque!
