What to pay for L99 VVT cam swap? - Page 3 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Custom grind by Ryan at GPI. 216 228 118 629 612

Another forum member on here did an LS3 conversion with 214 228 118 with a lower lift back in 2015 by Ryan and made 424 on GPI's dyno with stock heads.

I know some will say no way with this small of a cam but I am betting based on similar sized cams 450rwhp isn't out of the question. I am thinking it will put down close to an SS1 vvt with stock heads and intake with a stockish idle. I was told 15hp less than an ss1 so with heads, ported intake and rod mod and bumping compression up to 11:25-11:5.1 it will be close to that or a little more and with close to stock idle. Cam will only have -14 overlap. It is very close to a Lingenfelter GT11 but with the benefit of VVT. Lingenfelter makes a 550hp motor with ported heads and the GT11 with 11:5.1 and they rate it at 550hp, so we will see.

Yeah I kinda wish I would have stuck with the SS1 and stock converter. I made 438rwhp with stock compression and heads

I have a 3200 now and it is great with stock cam and will work great with this cam. If I add gears I either want to do 3.45 with a smaller tire to bring it to about a 3.55 gear or 3.70 gear.

I think I paid about $3500 for parts then did the work myself and sent the car in for a tune which was an additional $600. If you know how to wrench it saves you a lot of money. $6K sounds a bit high but not out of reason for a cam swap, especially if they are installing a new oil pump, which is a PITA on these cars if I remember right, you have to drop the subframe to get at all the bolts, and stuff.

I currently have a Circle D 3600 stall and that's the thing that gets me is the cam. I have a surge at around 1300 rpm with this SS3 cam that prevents me from locking it up until 60 mph in 6th gear because if it gets down to the 1300 rpm or below 55 mph it starts a chugging like a train. But I'm willing to bet your cam selection won't do that. So good for you on that cam it should drive very well.

ss camaro-monte · 11-05-2022, 01:17 PM

You shouldn't surge like that. I have seen plenty of the ss3s on the street and I don't think anyone every mentioned that with your stall size. I would call GPI, I bet the can fix that up in a mail order tune.

No, my cam is milder than even the ss1 vvt. MY cam is supposed to be down 15hp on the ss1 and 40 or so on the ss3 but I wanted totally drivability and honestly this isn't the car I want with the lumpy cam. That is my 87ss monte. I am betting with the heads and all the bolt ons this cam will be running as fast as a ss1 with no other mods or a little more. I wouldn't be surprised if I can get close to 11.5 with this set up. Right now I have 370rwhp and I can cut a 12.3. I am guessing 11.4-11.9 is possible even with this baby cam.

This for sure. I can drive my car at very slow speeds in parking lots in either D, S, or M1-2 and the car does not surge/buck at all with my 4500, even was docile with the 3200 I used to run. Something is not set correctly with the trans/converter tune. It shouldn't do that, mine never has. And I have a stage 3 TSP cam.

But it only does it when I'm cruising with the converter locked up at 1300 rpm. You guys are saying yours doesn't do that?

ss camaro-monte · 11-05-2022, 04:45 PM

1Jewldssrs isn't VVT, I don't think. I am vvt but stock at the moment. No I have no surge but I have driven in others with cams like yours and they had no surge.

Call GPI and they will tell you if it is normal for a VVT cam with your set up but I have heard of the cam surge you mean. All where because the tune wasn't 100%.

Mine will do that if the converter is locked in manual mode and the RPM's are too low for the gear I'm in at cruising. Mine locks at 57 mph in sport mode which is about 1300-1400 RPM. No bucking/surging.

Correct, I'm a VVT delete, LS3 conversion cam.
