Here my wild thought(and next money wasting endevor)

An all-wheel drive astrovan that your freinds dad flipped that you can get for $200, swapping in a 468 which I already have, and building it as a coumpound turbo-Miller Cycle/modified Atkinson cycle engine with mechanical alcohol and progressive nitro-methane injection.

Yes I am retarted and a bit overly optimistic, but I believe that because of the progressive power delivery and some good luck the drivetrain will hold together with minor modifications.

This is something no one has ever done, but I believe, because of the different loading dynamics of this cycle I can make 1k plus HP without turning over 5000 rpm, and with less-than-exotic parts.

Estimated total cost-4,000 on top of parts I already have. EDIT:Standard crankshaft rotation
