I have an 80 with a ZZ3 and a 3:07 rear. I've added Twisted Wedge heads, a Carb Shop Stage II Quadrajet, headers and a high-flow cat. I've heard good things about the Hot Cam, and I'm considering upgrading.
The car is street-driven only so I need to know: 1)will I lose much low and midrange torque with this cam?
2)any chance it'll still pass emissions (it currently does now - barely)
Thanx!

 

Since nobody responded, I figure I'd share my experience with this cam. I had the LT4 HOT cam and rockers (Crane gold) in my '94 LT1. The only other mods were long tube headers w/cats, Borla mufflers, and a cold air intake. Here are the results from the dyno (values at the rear wheels)

Since the torque is 324 (about 375 at the flywheel) at 2300 RPM, I don't think this cam gives up much on the low end.

I cannot comment on emissions as it was never tested.
