Response to There is a dork flowed a C8 and a C4 and got 213 and 231#.500 intake

Mildish cam, 2.19 intakes in D0VE heads with flat-tops and 1.65 intakes. He ran it in a '68 Cougar. The intakes flowed 302 at .550 and the exhausts did a measly 148. The engine dynoed at 500/500 and would melt the tires to the rims.

My FE C4AEs at 12 degree angle cut with the widened ports and work that had been masterfully done on the port pinch, flow 274@.525 with 2.055s and 185@.525 with 1.58s. The angle cut and a chunk uf worked intake with the same pinch as I had quieted way down, BTW. It dynoed 452 and 488 out 394 ci. Thats not "hero" territory, but it is the sweetest sounding thing you ever heard.
