I am ordering reproduction pre-fabricated fuel lines for my 1964 Lemans. My engine is .060" over 472, oversize valves, ported heads, cam is a CTA/225T-D lobe centers 110 degrees, .504"/.534" lift with stage 2 rocker assembly. Advertised duration 270/280 degrees. THM400 trans, Chevy 12 bolt with 2.73 gears. Yes, that is two point seventy three. Edelbrock Performer manifold, 750 AFB carburetor, headers. Application is primarily street use. Will a 3/8" fuel line get the job done ok? It will have a 1/4" return line. Any other opinions on my combination?
