I have that 327 AFB intake manifold in my garage and to me it was the best intake up until the Q-Jet came out and Z-28 intake.fdicrasto wrote: ↑Thu Sep 27, 2018 8:33 pm Here is a little info. The 62 250 hp had small valve heads and a rochester 4 bbl. The 62 300 hp had the "461" 1.94" int and 1.50" exh. valve heads and a carter AFB 4 bbl. 66-67 nova/chevy II engine blocks were all alone because of oil filter deepened location due to location for stick shift pivot ball for cross shaft location. Grumpy also said these blocks had a higher percentage of nickel also. I will add more later if needed.
Now BTTT, remember that some ratings were with single exhaust vs full duals...
