you know it

it's for my S2, still have the XR3i shell that i'll track one day, would rather get the S2 sorted first.

looking for anything over 200bhp atw, using a 1900 on a T34 with Cossie Management. I'd rather keep it driveable and try to make the engine as strong as possible so its built to last. Not a good start using a tall block

i fancy the 4" outward rolled but wasn't sure on how big/small to have the bore, was thinking 3" but i've been offered a 2.5" for cheap cheap
