327/300 carb CFM

Reed Granrt · 05-06-2013, 09:33 AM

Going in memory, the 327 with 250 hp had the 283 cylinder heads with a 1.75 int valve and a 1.5 exh ,small intake with a 4GC car and small exhaust pipe. The 300hp had the double hump heads with 1.94 intake valve with 1.5 exh with a larger intake manifold with the AFB with larger exhaust manifold. I started going thru some dyno sheets where I pulled the 250 intake and carb and installed a AFB and int. I think we picked up some hp but the heads were a restriction. Some of you guys will probably remember more than I do
