What 351w would be able to make any power? Even the rare D0 heads flow same/less than gt40P's. They barely support a 302 let alone 351 inches.
Reminds me when Ernie Elliot built a 327" for restrictor races and qualified WAY WAY quicker, so nascar made the "minimum cu in" ruling.
What secret am I missing where a top end that is barely enough to feed 300 cubes will run in a performance category with 50 more cubes?
Edit: On Stan's site I checked out the basic heads from ford/chev/dodge.
Mopar 051 head 1.88/1.60 (no idea if its good or bad)
50/49 113/97 165/123 188/123 193/137
Chev 462 1.94/1.50 (again no idea if this is a good head or not)
50/54 119/88 167/116 198/128 212/134
Ford E7 (as good as any and better than most stock ford heads) 1.78/1.45
52/39 95/74 132/98 143/104 159/109
To me, ford heads barely flow enough for 302's and once you see what 360's and 350's have for "base" heads, the 351W to me is way under headed.
Richard Holdener ran a stock junkyard 302 and got 259hp and a stock 351 got the same but at a lower rpm which to me says as cast, stock heads will flow enough to produce 260hp and that's it. (for a base to start from)
Am I reading something wrong??
