Maybe too early, but I want dyno/track info about anyone who has tried this. Is a true 400HP (@motor) or 320 RWHP possible with this?

Ralph has the baddest stock bottom end L98 I've seen on here. He runs mid 11's @ 115-116MPH with a wicked converter and slicks. The car has AFR 190's that are ported, SuperRam base and runners that are ported, and the LPE cam, and it costs $3500 (when all done) for just the heads, cam and intake setup.

I want to know how much less power a ported SDPC Vortec TPI base and ported Vortec heads can make with the perfect cam and TUNED! These heads I can get beefed up for the bigger cam (used) for $400 and another $400 for the base, $800 for the runner/intake setup, and about $400 for the cam. That's $2000. I'm hoping I can be a tightwad AND pull this power. Do I have to be the guinea pig?

Not really, that's the combo I'm going to go with VERY soon

SDPC Vortec TPI Base
LPE SuperRam Plenum/Runners
BBK 52mm TB
GMPP LT4 HotCam
2400-2800 stall converter
3.07 gears with 26" tires.

Thanks Tim. I'll look forward to seeing your numbers as you tune it. I'm about 3-4 months away from gutting the top end, and I only want to do it once without being disappointed. Keep me posted!

This sounds like a very interesting combo. If my car was stock to start with this is the direction I would have gone.

TIMSPEED: Can you run the LT4 Hotcam in an L98? Are the LT1 cams the same as L98's?
