331 ... N/A now ... KB later ... approach?

If this combo puts out 350 N/A, then I don't need the blower. Later I can put a centrifugal blower on if I want, or turbo it.

FWIW, I am looking at some ported Windsor Senior heads with 64cc chambers and Manley valve train components. If I can get them cheap, then I have my heads.

If you plan to do boost later will you get the cam grinded for this?
I would do 9.0~1 this way you can make good power N/A and still boost it later on
Just make sure you get some good flowing cylinder heads/int and match the cam up

I put $$ down 350rw wont satisfy you long!
