Default Next round of mods...

-AI 226cc 243's milled to 60cc (11:1)
-Appropriate length pushrods
-LS7 lifters w/ new LS2 lifter buckets
-SDP LS7 clutch & aluminum flywheel kit
-SLP 25% balancer
-Ported throttle body

Going to clean up the manifold while it's off as well, nothing major, just make sure it matches up nice n all...


Should feel a big difference right? I'm pretty excited for all of this to come in the next month or so!

Looks great!
I would not bother with the ported TB though.

I keep on wanting to swap the current cam out, I just keep telling myself I like tq, I like tq... Lol hopefully that cam goes nice with those heads on the street, I wana keep my throttle response crisp and torque nice n punchy in the midrange, overall just keep velocities up.

The clutch and flywheel alone will be a huge SOTP gain in 1-3 gears but not so much on the dyno. Some have gained 10-11 at the wheels with a lightweight flywheel setup. The gains are multiplied in the lower gears though.

The heads, pulley and TB should get you approx 40rwhp.

Did you ever end up racing that M5?

I had the same thoughts about all of that... Was hoping for 40-50rw, so thats nice to hear someone confirm. if I hit 450/420 I'll be happy with that, for sure.

We haven't, believe there will be vids no matter the outcome, and it will be before I do all this new crap to the car.

Yes it should run good, but while your spending the cash Id throw a FAST 90/92 on it and that would put you around 470-475. You can get at least 300 of that back by sellign the LS6 intake.

I would have said the hell with heads and bought a nitrous kit.

I put my old ls6 intake on ebay a couple weeks ago and sold it for 550 with 50 shipping. someone just chose the buy it now within an hour of putting it up. i would shoot high and slap it on there for 500 lol

on this forum, they go for 300 from what i have seen. Now ebay they will go higher because of the broader market that you are reaching. But for the extra 200, i would put in on ebay and have a reserve of 300, haha.
