You can't just replicate the top end of this thing...
timing cover, sump, upright kit, manifolds, water and oil pump and pickup. I'd guess its bottom end is built like that of an... f1 car.
Then there's ignition & fuel system, crank gear, cam gear, cams, followers, valves, stems & seals, rocker cover. Shit the list goes on.
You'd have to be real keen because i'd estimate five figures each. I don't mean to dash hopes but the block alone probably needs thousands spent on it. It wouldn't be running a stock crank or bearings for sure. You could expect to be building an engine from scratch....
Good Luck any how.
