Find a "230" casting 400 block Ported Stage V Hemi head conversion Big cam .800" lift, 290* @ .050 Twin dominator tunnel ram 15:1 compression ratio dry sump
edit: forgot to post stock size crank and bore
Throw on some big headers and it dynoed 1008hp at 9500 floating the valves on my Engine analyzer Pro simulator lol
Thats some funny stuff right there lol. I do know that it can be done, I just don't if any of the heads available will support it.
Because Larry Pritchett's 390ish ci BBC made well over a 1000HP a year or two ago. But of course, it wouldn't be fun if it wasn't a Mopar
It can easily be done, Formula 1 engines just a few years ago displacing 3.5 liters (roughly 210 ci) were reving to 18000 rpm and making 950 hp. Pro Stock trucks were 358ci and made 980hp. It would probably be just as doable with a smallblock.
