My cam is 232/240 .580/.580 110+2
I lucked up and bought it used, but the engine builder said he wouldn't have been able to build one much better. It ramps up quick and builds torque rather quickly as well. It's a very responsive cam. I used it for several years with a stock LS1 with 241 heads. The recent build was with the addition of AFR 210cc heads and it made 521hp at 5900 and 472lb/ft at 5400.
This is in a 3500lb C10 with a 700R4 auto and 4.11 gears.
If you plan to run 4.10 gears, you'll be shifting into second quickly and staying in second through the run depending on the course.

It was a custom grind for Brian@KYTP, who is no longer around. I'm pretty sure it's from COMP Cams, though.
Yes, those numbers are at the crank. It's still the stock bottom end and pistons, but with the new heads and .041 Cometic head gaskets, CR is probably between 10.5-11.0:1
