Cam ford 302, want lopey idle, low end torque, possible?

I'm rebuilding a roller 302 for my brother. He wants a lopey idle but still wants all the low end grunt he can get. I don't know if that is possible. I told him a cam with any lope will need some rpm to supply power and torque, like about 2500 rpm or more.
He has a C4 and 3.00 rear gears, 71 Comet (Maverick).

Does anyone know if there is a hyd roller cam that will lope and still pull good off idle?

A friend mentioned a Thumper from Comp Cams and also a Ford E303 cam.

Please list your experiences here.

Thanks.

Re: Cam ford 302, want lopey idle, low end torque, possible?

Arrgh...this question again. I've had several friends ask me this question, and they never bother to add in any specifics, like "I want it to idle like a Top Fuel car". When you're looking for lope, that's the #1 question.

Personally, an RV cam is lopey enough for me...just so long as it doesn't sound stock, I'm pretty happy. For some people, they just have GOT to have that 1500rpm drag car idle, so it takes a lot more agressive cam to make them happy. The Comp Thumpr cams are designed to give decent peformance and lope like holy *** but IMO you can settle for a cam that's milder sounding but better suited to your engine and kick the Thumpr's arse, performance-wise; just so long as you don't mind giving up some of "the sound".

All of the Ford cams (B, E, F, X, & Z) are at least somewhat lopey, but they aren't the best perfoming units out there. A Trickflow #1 is in the same "cheap cam" catagory, sounds pretty darn good, and will kick arse on the Ford cams. One of the newer Comp cams would run even better and sound good, but they do cost more. Another option is a custom cam, and depending on what pre-made unit you're looking at, it might not be a whole lot more $$.

If you have to pick a Ford cam (they are cheap used) avoid the B cam no matter what. The E cam sounds very similar and perfoms better, and the F & X cams are surprisingly good in every way, considering they're OLD technology.

The old cheater cam was a Blue Racer WG-1087 or Speed-Pro CS195R. Sounded just like a B-cam and flat-out flew. That would be a good choice if you could find one...the newer technology is better, but this cam is still VERY respectable IMO.

I'd probably pick the Blue Racer, TFS, and E-cam, in the order of best to worst, if I had to pick a cheap cam with good low end. Just depends on what kind of $$ you're looking to spend.

I've got a b303 cam in my 302 and its kinda lopey with lots of low end. I do think i will switch it in the future though, i want to squeeze more power out of the engine.

Amen brother. The whole concept of the Thumpr cams bugs me. They might as well have named them "Poser cams". That said, they can make decent power. They'll just never be optimal for actual performance.

But back on topic. Here's a key question. Will the engine in question be carbureted or fuel injected?
