Hey Everybody, new to the group and the LS world. I've been an old school SBC guy all my life but just purchased a 1949 Ford F1 with a 2002 5.7L LS1. Truck is built solid and I have to rebuild the transmission (4L60e) and am going to go through the motor (stock) while it's out. Truck is built for street/strip with a 10 bolt chevy rear end and 3.73 gears. I am curious as to what cam and valvetrain you would recommend for street/strip application with 100-150 shot of nitrous. I am not planning to bore unless necessary and plan to run aluminum heads to match cam. Just curious as to what you folks would recommend.

Factory weight was ~3200lbs and it was originally a v8 truck. I'm guessing here but probably at least that maybe a little more.
The flowtech streetsweeper HT has always been an awesome cam for street/strip applications. Specs are 228/232, .612, .600, 111+3. With stock 241/852 heads, it's usually near or over 400hp and 380tq with headers and full exhaust. With 243s, at least 420hp and 400tq. Good some reviews of it on this site, corvette forum and ls1gto. It will cost $570 shipped for the cam though. Overlap of the cam is 8 degrees.
If you wanted a more affordable cam, you could look at the summit 8707, 226/236, .600, 600, 113+3. Overlap is 6. Summit has packages that include springs, valve seals, etc for great prices. The summit 8715 (222, 234, .600, 575, 115+3) is an even better for driveability and great up top for the track. It wouldn't be as powerful as the 8707 though.
Texas speed and cam motion have lobes that are easier on the valvetrain. Bald eagle NA cam from TSP is solid 227, 234, .600, .600, 111+2 (8.5 overlap). Cammotions titan iv is also good at 227, 232, .612, .595, 113+4 (overlap 3.5). These two won't produce the same power and torque as the streetsweeper ht or even the summit 8707, but they will be easier on the valvetrain. Everything is a tradeoff.
Not sure how we missed this thread. That's an awesome truck you have there. We like the direction @Abs is thinking here. We'd typically stay in the "truck" cam range for a truck. However, with this combo, we can do things a bit differently.
We also think the SUM-8707R1 would be a great fit here. If you don't mind a steady lope and are ok with a 2,500+ converter we wouldn't hesitate going with it. ABS mentioned our cam kits. We have a variety available for most Pro LS cams. Check here for all 8707R1 kits.
