Default cam upgrade worth it?

im gathering parts for my turbo build and wondering if upgrading the cam is worth it. stock 98 shortblock ls1 with 317 heads and on3 turbo kit (76mm). want to keep boost under 10psi to make the motor live longer. not looking for a certain hp. but more is always better... any info would be appreciated

I would just turn the boost up a bit. Normally I would recommend a cam but you can still make good power and torque on the stock cam, and that turbo isn't going to benefit a lot from a large cam. If you do swap cams, keep it fairly small.

If the engine is already in bits, then yes a cam would make sense now.

If it's already together, wouldnt worry too much about it

Id do a turbo cam! I ran a ls7 cam in my car for almost 2 seasons and was happy with it. I switch to a custom tick cam at the end of last season and let me tell u there is a HUGE differance. On PAPER the cams r with in a cupple hp from each other and the power curve in nearly the same as we'll on the same boost. But driving it there is a night and day differance! It spools WAY faster at any rpm and is so much more fun to drive. At the track there is a huge differance, on the same boost my car picked up 7 mph and nearly a half second. It's the best 400 I've spent on it so far!

installed a isky triple 12 cam from JFR and went back to the track

that is a significant amount of power

a "turbo" cam will def help make more power. that said a 4.8 truck cam is significantly smaller then a stock ls1 cam as well.

i dont have an exact goal but want to optimize my setup. will definitely change turbo in the future so if a cam will work with the on3 setup im not against swapping it out.

martin smallwood at tick or john bewley at liljohn motorsports are your best bet for getting a cam.
