That's a pretty snarly cam, but since you have a 4 speed you can cheat a little. I think 3.73 gears should put you in the drivers seat, that's if you have normal sized tires. You should be close to 410 lbs of torque, your intake will rob a little low end torque. Not sure what rockers you are running, if stock stamped rockers thats probably a weak link. You should be able to buz this baby to 6800. What kind of claims did your builder give you? Sounds like a good stong daily driver, with the exception of the cam may be on the big side but like I said having a 4-speed will help you out on that.

I would not use any gear over 3.23 since you are not driving it at the track. Too many RPMs would only put unessessary wear on your engine. as far as torque get a copy of desktop dyno and it will tell you everything you need to know even what gear to run

I tend to agree with Sneaky Pete. With a 292 cam and a single plane intake, you won't make any power at all under about 3000 RPM and it should rev pretty good. At 60 MPH and a 3.73 gear with a 26" tire, you will be spinning the motor at about 3300RPM. With a 28" tire, about 3050 RPM.

that cam, the single plane manifold, and the 882 heads might not be the best for compatibility unless the heads have been given some work. I would say that the 882 heads may hold you back.

with that cam, I agree with a 3.73 gear.
