indeed, wat car/engine you got to have a windsor v8 in it then?

stock 302 block will shit itself somewhere between 500-600bhp at some point even on stock internals, and even a 351 block wont last that long at 750 unless its an early one.
aftermrket ones are different story tho.

thats not a complete bolt on kit anyhow, as i know them manifolds, and they are meant for internal gate turbos, so will need to do some welding.
