MAV1970 would really like to do that i am computer ignorant so i am working on it doing good to do what im doing sorry will get it done 4 long
still no answer to my question what is so bad with the 400 or 400M? more displacement = more horse pwr?
Nothing wrong with the 400. But the biggest drawback to making power is piston availability, to be more specific, the lack of an off the shelf piston that's got a pin height that will get the piston top to a zero deck, instead of the stock -.100 to.125" deck clearance. A piston that's that far down the hole at TDC is an excellant detonation generator. Combine that with the open chambered heads (or even trying building one with quench heads) they came with and well you know the rest.............................
