Anyone running the Comp Cams 292?

It'll be fine, I have no issues with powe brakes. Vac guage reads 9-11" @900 rpm. I would agree this cam likes alot of carb and initial advance, once tuned tho its very streetable.

It's ok for basic street use, but for better braking consistency, manual brakes, a vacuum pump or hydraulic boost are a better plan with a low vacuum cam ... or run a smaller cam.

I only know one person who had that cam, and it was an 8.5 cr 350 Nova with auto, and not much gear. It was a dog off idle. I would think that you need at least 10:1 compression, a 3,000 rpm converter, or a 4 speed with at least 3.91 gears, a set of headers, low restriction exhaust, a high rpm intake, and a big carburetor.

I'm running a Bullet roller. It degreed 283/285@0.020, 251/249@0.050",109LSA/105ICL, 0.616"/624" gross lift w/ 1.6. Spec'd for peak hp@6000rpm +/-. It has 10-11 in.Hg @ 850rpm idle. Noticeably reduced brake boost vs. the 224/234 hydraulic that was in it before. A vacuum canister helped.

A stick is much more forgiving of too much cam, but with the rear gearing needed for a big cam, really wants OD if you're looking for reasonable rpm cruising. I'm running a T56 and it's a much better combo than with a 727 auto w/ high stall.

If the OP has a 292 Comp, by testament of others it is streetable with the right gearing and a stick or high-stall auto. If considering a new build, there are better options out there both for street and strip. If you don't mind adjusting lash, a solid would be a better choice for a bigger cam.

You can crutch the < 5500 rpm performance of cam that is a bit big for street by running a small-runner intake like an AirGap or ProFlo, small headers and higher ratio rockers (if your heads flow at the higher lift) ... like Jtsllc1 found in his tests. It will boost cylinder fill at lower rpms to boost torque, but give up some top end. A smaller cam would generally be a better plan for a true street car. I have an AirGap on mine to help the street manners.

Original plan 10 years ago was to hit the strip and track, but life got in the way and never got there, so plan to detune with a smaller cam to make it a better street car.

More info than you were after, but hope those considering a Comp 292 are realistic in their goals and build ... a 280 or similar would generally be a better performing street choice than a 292.

Hope this helps,RD.

On my set up the power brakes were inconsistent so I upgraded the brake set up to manual brakes. Road racing is brutal on vac assisted brakes.

Just my opinion the cam is to radical of slow driving such as 4wheeling....i`ve run the cam and i`ve been 4 wheeling since the 80`s...That cam does`t turn on until 3,000+ rpm...there are much better choices out there
