Cam this Nova
Hey Guys/Gals,
After weeks of researching I still cannot find a cam I can bring myself to purchase. This is going into a stock 98' ls1.
The car is a 62 nova, full cage, t56, Jag IRS.
My Plans:
Cruise this summer. I want a driver with more than stock power. In the future (this next winter) I wish to turbo. I am at school and have no available tuning shops. I do eventually plan on doing the tuning on my own. (Getting my masters in Engineering)
Therefore, I want a cam that makes good power in the upper rpm range, has the possibility of accommodating turbo(s), can drive reasonably on stock tune, and not have ptv worries.
Parts I have now. Jesel Shaft mount rockers, .650 springs with ti retainers, rod bolts, oil pump, timing chain, pushrods will be ordered when length is determined, various gaskets. I can get a set of 241 heads for free, "good" heads will be a year or so down the road as well as intake.
I autocross, beat the living sh*t out of it, and want to see some road course action eventually.
ls6 cams seem to work well with turbo's but I am afraid I will be unimpressed and regret it. I want something with usable power to around 7000.
Thanks!

I'd also post in the Forced-Induction section.

Regardless of which cam you go with I'd at least get a mail order tune.

Since you wanting around 400rwhp and go turbo with the same cam it's going to be a compromise. You don't want to go too big since you'll want to keep the overlap down for the turbo, now if that 400hp is at the flywheel that shouldn't be a problem.
BTW if you're willing to go with more aggressive lobes you'll get more power out of a smaller cam.A good option is to go with some Comp Cams LXL lobes (boost friendly),maybe like a 226(.605")/226(.605") 114lsa. That'll keep overlap down (-2*), and will still make good power before the turbo build.
Or the option I sent in you PM.

you. must. post. more. picture!!! Sweet build man im so jealous. Sorry not enough experience with turbo cams to make a good call for you but the cam right above seems like it would work well for your setup. I dont think that cam will make power to 7000 like you want.

Yeah, with that cam I'd run it advances 2-4* for now, then when you get the turbo on run it straight-up with no advance and that'll bring you power band up 100-200rpm. I'm not sure what lobes the SI TU1 uses (possibly XER), but(IMO) I'm sure the LXL lobes would most likely work better.
