just got back from the track and there was a 70 429 mustang that was stock except for slicks and it pulled both wheels up and ran 8.21 om the 1/8thFATHERFORD said:the 70 boss 429 mustang was WAY under rated...
food for thought.
I was really wondering how do you make more Hp than a 427, 428, and a 429 with J/Y parts and a so called crank that a machine shop wants to charge you more to work on it? When I mean more 479hp is 109 hp more than a 70' 429 boss mustang. Do you got any links to show where a 351M came with canted valves or even a 4 barrel carb? Most of the 351m/351w/302's where two barrels making them crapy heads to be useless since the runners are pretty small. Also can a 351m head bolt on to a 351w? As an exspample only; I know a 351w is basicaly a 302 which you can't bolt a 351c on to either one unless you got some real money on you. That is because of the way they both pass water in different ways and the intakes that allow a 351c head on a 302/351w is VERY rare. (thus the 302 boss mustang)
I really would like some links so I could double check all this crap I rattled on about. There are kits on the net to make a 393ci sbf w/465 hp but using aftermarket heads / Cam and a few other things but nothing so fair making that kinda power on stock 351m heads/ stock Cam
I don't know of any 351M that were 4 barrel. The heads are definately canted valves(I'm looking at them) The big difference in these and the cleveland heads is these have an open chamber w/ 76CC and some clevelands have a 67CC closed chamber head.
