I like the 428 crank and.............
a 455 block .030 to create 440 cu.in's.
You can use the SRP 4.185 pistons and a good rod and let it eat.
I think this is a good forced induction combo and ran it myself.
My current Funny Car blown and injected set up is a 440 cu.in. deal.
As was my ATI Procharger set up that ran 10 flats with a P1000b unit in a Street car.
Build it fast, build it right, build a Pontiac.
