Help me win this argument 400 in a 72.

hmmmm here is a 383. not stroked. compression 11:1

runs 9.9 seconds quarter mile in a road runner.

yeah a 400 at 12:1 would be even more powerful.

comparing a 451 stroker (400 with a 440 crank) at lets say 9:1
vs
a 400 with lightened forged crank, aluminum rods, 12:1 forged pistons, MP stage 6 heads, victor intake... running on race gas

which would win in a 1/4 mile?

True, but..

Which would be a more streetable engine? This guy wants a street car.
