bcam in an auto?

is the bcam too large for and everyday auto?

Not really, its very lopey though. Any other mods?

I assume you're talking about the B-303 Cam? It really depends on how much you're willing to sacrifice, the other thing is the B-cam is not emmisions legal. You might need a converter also, according to Ford, the B cam is designed to produce power above 4,000 RPM. I'm not a big fan of the 303 cams, in my opinion there are better cams out there, they also don't have much lift. Like I said, it really depends on how much you're willing to sacrifice. Here's one that I think would work well on a daily driver automatic,

The B cam in not really auto friendly, and I would shy away from it. Really you should match your cam to the stall speed of you torque converter for best driven performance.

no real motor mods yet, im still deciding on a combo. im just gonna be patient til i think ive found the best one to my preference...this kinda thing takes alot of thought! thanks gusy

Look into edelbrock's EFI selection. Their Performer RPM II is very nice and they have a matched hydro roller cam as well as a set of heads dyno tested and matched together.
