The E cam is susposed to be good with the 94\95 computers & has good mid range power, but falls a little short on the upper end, good tq.. Stay away from the B cam. Not sure on the F?

It seems to be the consensus that no matter what cam you put in there you run the risk of needing to tune.

I have found a few running the F cam without tuning probably due to its 114*lsa. Its weak point is no low end and power doesn't come on untill around 3000rpms.

The Steeda #19 is supposed to made for out 94-95 Mustangs and yet some still need tuning and some don't. It also seems to have soft lower rpm.

Maybe just try running 1.7:1 roller rockers with the stock cam and see if you like it. At least you'll know you don't need a tune and it does have great low end.

You want a wide LSA cam that pulls good vacuum. Neither the E cam nor the B cam have this. Some of these problems can be fixed by adding fuel pressure and twisting the distributor, but I feel that these tuning methods are bush league when dealing with fuel injection.

The F cam is a good forced induction camshaft, and does pull good vacuum with a wider LSA. It will most likely be your friendliest alphabet cam.

The e-cam gained a lot of popularity in Fox mustangs, because it does prove a decent pickup over stock, using their computer. Ours are different.

Save up and buy a custom cam. Until then, buy some 1.7s and retard timing 4 degrees. Your custom grinder will take your 1.7s into account so the money won't be wasted.

Exactly. You wouldn't drop a new carb on your car without tuning it, so why do peeps think you can drop new parts onto an FI car and not tune it?

The key to a great combo is that everything has to work together. The tune is the glue that keeps everything working as one.

I did a good amount of research on gt40 heads and what numbers they like cam wise.

The gt40's will like a split patt. that fav. the exh. side (ie. NO letter cams). For the intake the number was around .490-.500 and .500-.510 for exh. with a dur. that favors the exh. side around 3-5.

I went with the TFS 1 cam on my unported gt40's, the numbers are alittle on the high side of what gt40 heads like but not too bad to make it over-cammed. I ran the cam 100% un-tuned for awhile. I had a bucking at part throt (found that to be a C&L maf issue though), cold start was rich and would stall, every blue moon it would stall after warm up after a quick slow down to a stop. I could catch it every time on the slow down to a stop and it only died like 3-4 times in a few years. Ran GREAT for the combo I thought...I really wish the shortblock didnt crap out on me to run it more.
