Default Build around new cam

I'm looking at a new cam (Comp Big Mother Thumpr) so I'm looking to upgrade the internals on a stock LS2. I've found a kit at Summit Racing from Comp Camps themselves that includes all the parts I said.

Would you guys recommend this kit if I wanted to build a NA street fighter engine or get the parts separately? Also this will not be a daily driven car so the rough idle of the cam won't be a problem.

Thanks

I'd buy seperately. Look up the PN for the cam you want on Comp's website. All of the recommended components will be listed by part number, including springs.

The thing about that is there's several different components with several different recommended versions by them :/

Those cams have an intimidating name but there are better cams out there for Ls2.

I suggest the FTI Streetsweeper HT, 228 232, 612 600, 111+3, rough idle, OR the FTI Shark, 232 236, 600 600, 113+4, slight chop, good idle. Which to use would would depend on stall and gears, and preferred sound and idle. Both are good street/strip, weekend warrior cams.

This cam sounds like a better idea, thank you! Now I just need to find the right springs for this one.

That seems like I'd have to mod the bottom end to get it to spin that high?

Car in question is a 2005 HSV GTO manual.
Engine has never been opened other then for cam change.

At the track shift at 7,000rpm and have had the best ET's leaving it in third gear as it crosses the line at 115+ mph.
