Any one see the dyno test results on fordfe... 6 different intakes that everyone runs ... quite interesting (surprising for some).

Saw it. Kind of embarassing. 385HP? That's well below 351C + stock head production numbers. Wonder if they were building an econobox motor?

I probably wouldn't have guessed the Streetmaster either.


I had one of those on a mild 390 in a '66 F100 shortbed....it for sure pulled like a freight train.

Interesting reading.I wonder how much the leaky exhaust valve hurt the total power output?..I would have thought the engine would have made 400 hp or more easily????

The issue wasnt total HP, it was comparing manifolds. It was a nearly bone stock 428, dont let the numbers draw you off intent. The issue is that the "best" intakes did poorly, and the "worst" intake by FE guy standards did the best by significant numbers.

Point taken as I know they didn't spend much time tuning any of the combo's.He says he has another 428 with the same problem(leaky exhaust valve) and he's doing a before and after dyno test so that should show how much it hurt this motors dyno numbers.
