ap72 The bigger concern is your transmission choice. There's no sense in running a 700 when a TH350 will do a better job and cost much less.

DoubleVision Build your 400. Use 5.7 rods. Have the bottom end balanced by a good shop and you`ll come out alright.

IMHO no 6500 is not to high someone may say different but i know with my 408 6500 is easy. 5.7 x beam rods flat top pistons dart iron eagle heads and more. I guess something to think about is just how often are you going to be bouncing off 6500 RPMs anyway.
