Matt,
Clifford sells the intake if you don't have one.
My plans call for a built 292 with side drafts in a Lakes Modified. Mine is still in the planning stage but I'm collecting parts. Your 250 should be a very strong runner on the street. If the Supercharged, nitrous V-8 guys can run on the street, your tri-powered inline should be just fine!
