318 Street/Strip build?

I guess we should also ask-where are you starting?

You say 65 Val, 3 speed...slant car? or 273 2bbl? 3 speed stick or auto?

BLUF: Need more info to make any real recommendations.
it was a 3 speed Slant car but that 3 speeds not going back in. I have a newer all cast unit I'd like to use
