What Cam does my 5.0 have ??

I bought the car a year ago and was "told" it had a 93 Cobra long block and "A BIG CAM" in it.

I'm REAL curious as to what the specs (ball park) may be on it.

See sig below.....

The engine has a TON of low end torque and will burn the tires from a standing start (with 2.73s BTW). The idle is pretty smooth and overall drivability is excellent.

The engine really comes ALIVE around 2700RPMs and is still pulling HARD past 6500RPMs. NO drop off in power what-so-ever.

What kinda cam would display these characteristics ???

I always thought 5.0's were pushrod engines... I could be a complete idiot though.

Push rod engines still have a cam... The cam is in the centerline of the valley, the lifters ride the cam lobes, which push up on the lifters, which rock the rockers, which open the valves. An OHV motor has a cam (or two) at the top of each head and the lobes move the rockers directly.

FWIW, my 89 GT with a 308, ported and polished stock heads, and 2.73's will burn the tires from a standing start all day long.

Ah I understand a little better now. I never knew if pushrod engines had cams or not. See.. i'm an idiot when it comes to engine internals :P.

Wow, I guess the OHC engines are more predominant than I thought. That question caught me totally off guard.

That was an 8-track what???

With those mods and a power band of 2500-6500+, probably something along the lines of an E303 or F303. But that's just a WAG. You really need to put a dial indiacator on a rocker arm to come close.

Cams like the E303 or B303 were pretty common. Crane had the 2040, IIRC. It's pretty much just a guess though.

Isn't the B303 cam pretty much the same as the cam the Cobra motor had.

Someone please enlighten me.

I am new to all this. My 5.0 in my 1985 GT is still stock. Can an E303 or B303 be dropped in without anything else modded? What kinda power increase would it give?

I have a HyperTech chip in it as well.

No idea where the RPM limiter is set at though.... ??
