I have a 224/224 112lsa cam and Livernois Motorsports stage 2 LS6's in my 98 z28 M6 along with all the bolt ons except a crank pulley. The car was tuned by a sponsor here but had a problem during tuning. The problem was corrected but i assume the car never went back. The car put down 379hp on a mustang dyno. During cold starts or even fresh starts I have to let the car warm up a little or it will want to stall. I say this shouldn't be happening with such a small cam especially since i owned 2 other lsx vehicles with bigger cams. Anyway anyone still run a cam this small alone or with heads? I'd appreciate seeing your numbers. thanks

Those numbers seem low for HCI, and it sounds like you are lean at cold idle, you still need more drivability tuning, i would expect at least 410-425rwhp imho

I am running a 224R on 112 with stock 241 heads and have no driveability issues. I do however let the car warm up before driving, if I don't I notice some idle surge with the clutch in and slowing down. When I let the car warm up I have no surge at all, I attribute this to the O2's not being warmed up. My car put down 366/367 through an LS7 clutch and aftermarket ZR1's, it is by no means a dyno queen. I have taken it to the track a few times on hard street tires and with an average 60 ft of 2.6X (horrible) the car traps 113-114mph consistantly. I hope this helps some, take it to the track and see what it can do dyno numbers don't mean a whole lot.

Thanks 02, was this on a dynojet dyno and do you have headers??

Yes, I have American Racing Headers 1 3/4" with cats. As to the dyno I do not know for sure but I believe it was a dyno jet.

CJ don't forget that was a Mustang Dyno that those #'s are from. On a Dynojet it should read more. Also, I think the Livernois heads are meant for a little bigger cam and should shine once you throw that new stick in there. Keep us posted!

Yooooo! Yea i know the numbers were on a Mustang dyno but the car doesn't feel that strong to me. I had a cam only car that felt stronger. I have a 233/239 in my garage now ill keep you posted with the new numbers

ITS A SMALL CAM. w/ THOSE HEADS, A 23X/23X OR GREATER I THINK WOULD BE BETTER. THAT IS THE SIZE OF THE STAGE 2 ON THEIR SITE.

Gonna move this to internal. You might get more responses there.

FWIW, your car will make 30-40 less HP on a loaded dyno than a regular dynojet.

For your stalling issue, check your idle air counts.
They should show between 45-75.
