I'm not sure what your tolerance for street manners are, but that'd be a pretty rowdy cam for a street car in a 5.3. There's not a lot of local guys playing that hard with the 5.3's, but a buddy is running an ASA cam (226/236 .525/.525 on a 110) in his car.

Have a 226 / .585 in my Dakota. Makes almost zero low end power. You probably won't like it If you've got a heavy ranger, but I like it just fine, spins 7500 all day long. Don't have any dyno numbers for mine, and I don't care to, it's just a reliable fun truck I drive regularly.

It's ground on a 114 lsa, 110 icl is what the cam card says. Powerband kinda likes 3500-8000 ish (fuel cut) with the Vic Jr. Haven't taken it to the limiter yet, but it's still pulling hard at 7500. With a carb I'd suspect more rpms would be on the table. Personally, I like a ragged edge setup, but I don't know what you prefer. I have a trex in the garage, and thought about tossing that in the lil 5.3, but after this cam, i don't have a reason to. I did read a thread where another guy stuffed a trex in a 5.3 for an alcohol tube chassis 69 camaro that went mid 6's in the 8th, 2600# n/a. Maybe that helps? I'd guess my junk might make 340-60 ish at the wheels, maybe.
