Blueprint 408 cooling system questions.

Strongly agree , ditch the 4 core and get the biggest two row 1 1/4'' tube rad. u can get in it , it will be thinner , and u can probly get the short cluth in it , I DID .
U MEANT 365 H.P. DIDNT YOU ?
What radiator did you get? The 2 row aluminum one for mine doesn’t appear to be any thinner. The thickness is 3 inches and that’s what my current one is.
