Quote: Budget build goes like this.Cast 72-78 440 pistons .030-040-060 over.About -.020 deck height.New rod bolts/resize.Balance to taste.If you use the steel 383 crank rebalance is mandatory.Low end torque?, go with the 60302-3 Lunati Voodoo.Dual plane not single plane intake.I prefer 915's to 906's and either to the 516's.If you prefer the 516 use the 1.74 exh valve not 1.81.2.14 int valve is fine in any of the heads.
I figured the compression distance of 440 pistons would be too much, but the federal-mogul P424NP has a CD of 1.912 vs the KB240's of 1.908. So not only is it slightly taller but the big advantage is it doesn't have that huge 5cc trough the KB piston does which I don't think you need for valve clearance anyways unless your running a huge cam? I guess the only thing is you have to have the block bored out to 40 or 60 over 440 size which is no big deal.
