WTF defines an EFI or carburetor cam?  Anyone?

I was speaking more from a general term. But carbs are more tolerable of aggressive cams than most factory and some aftermarket efi systems.

With few changes, a carb generally doesn't care if a engine makes 6" or 16" of vacuum. Thats definitely not the case with most efi systems, at least not without professional help.



And that is part of my point. That 236/248 @.050 on a 114 LSA has +14° overlap which in a 347 would make ~9-10" Hg.

We have used that cam in the past on a fuel injected 363 in a 95 mustang street car...@ 3500 pounds that car ran 7.0s in the 1/8th...it does require a tune with fuel injection. I'm sure it would run well with a carb.

That car ran a C-4 with a 5600 or so stall and 4.10 gear. The owner wanted to street drive it more so the convertor was tightened up to 4500 and rear gear changed to 3.73 and it only lost 2 tenths at the track but was much easier to drive on the street.

I've run a bunch of different EFI cams over the years, many with a carb.  The one that really sticks out is a bone stock '92 5.0 HO cam, used in a turbocharged 306.  Idled perfectly smooth and quiet but worked pretty good with the turbo.  I had it retarded, IIRC, 4 degrees.  Might have only bee 2 but it worked great for it's intended purpose (sleeper).

That's pretty funny Mr. Blue. I looked on Summit and that cam runs about $200 and is not recommended for cars with auto trans, unless they have a high stall, and/or steep gears. Which Ford cam would you recommend for stock Mustang with an Auto trans?

The factory one. Cars have ran low 9s with them, so don't count it out.

Even the stock HO cam needs more converter than stock, so any aftermarket cam will be even more hampered.

With a stock engine, spend your money elsewhere. Gears are probably the best investment, followed by a good converter.
