I have no intention of disparaging the GM engines I just am still doubtful that top exhaust ports add that much power.

Now I do agree that longer internal ports add heat but Ford seemed to have that under control.

Maybe the ultimate solution would have been 4 exhaust ports with 2 running between the outer cylinders. That kind of reshuffling could have made more room for 5 main bearing webs. It probably would have also resulted in higher cost.

There are several teams running flat Cad's at Bonneville.
I am part of one. Our engine is 375 ci and makes 600 hp.
It is in a 38 Chev coupe and has gone 189 mph.
