yes,yes,yes the block will break we all know that

if i had a 400 laying around i would be looking at that.(but i was not smart enough to buy any up)

maybe to make the rotating weight less, use alum rods. will alum rods fit in the 4.25 stroke 383?

it might not be a fair comparison but a comp eliminator motor makes good hp with small cubes. but does turn alot of rpm.

okay on
