hello,

just for pleasure of taking engine! Lets say you wanna have at least 600 hp, but mainly 650-700 hp…
we all know a 500 efi with a bolt on whipple runs around those number between 650-700, not sure about real numbers…
i also remember it is not overthinking a 540 can push 650 ish reliable hp
gm makes 620 hp and or 720 hp on race gas from 572 cubic inches. And i remember someone on the board had 632’s cubic inches but cant remenber how many hp he was pushing.

So many ways to play around those hp numbers
if you were to choose a recipe, what way would you choose? No replacement for displacement? Or blower? , keeping in mind dock friendly, and stay far from reversion, and cost of maintenance!
Please help.
Thanks!
I didn’t find the right solution from the Internet.
