looking at getting a ford b303 cam. If I remember right the 91 motor uses a hydrolic FLAT TAPPIT cam not a roller cam right???

roller..and pass on those abc cams..you need more lift on the exhaust

what does every one suggest. I plan on getting gt40 aluminum heads and 1.7 rr

vfast

why not get a cam based on the stock 1.6 rocker...saves $$$$$ and if you need more lift later just add the 1.7's...I need all mods of car to suggest a cam

ok this should do thanks.my best 60'2.33 and 13.78 at 100mph. I found how to leave at higher rpm's on the nitto's but couldn't beat my best on street tires??
Have I just hit the best a stock motor can do?? I have equil length shortys, and full 2.5in exhaust,pullies, short belt (no smog but I do have a/c) 373 rear, cold air intake,front sway bar removed,skinnies up front and 275 60 15 out back.

I have a b-303 cam, and it really pulls much harder than the stock cam, but from 4000 - 6000 rpm, my motor lost lots of bottem end power, till I advance my timing to 14 deg.
it is an alright cam, but after looking through a comp cams catalogue, I would have picked up an extreme energy series, or nitrous cam, but after you do it, you will probably get used to it and you will want more, so look what you plan on doing in the future too to help you pick the right cam.

although I have seen a 347 stroker with an 8psi supercharger and a b303 cam running in the low 11's.

I have built many engines with different cams so I have some insight on it.... people here can only suggest what they got ....
