I'm looking at swapping a L99 cam into my LY6 motor. The cam and tune were free, and it should have (even slightly) better performance than the LY6 cam. I've had a hard time finding a tutorial for the swap; I haven't worked on a VVT motor before. I plan on replacing the cam bolt/valve, but is there any guidance out there on the swap?

I upgraded to an aftermarket VVT cam in my engine swap thread that might help??

70Chevelle-LS

Sure, just looking for any pointers. Anything special about the cam phaser, besides looks. I'm assuming I'm still lining up timing marks as I would with a typical timing gear setup, and replacing the cam bolt/valve. Also, resetting the rocker arms to zero lash at 20 or 22 ft lbs? Does the motor need to be at TDC and spun 360, or do I torque them in place? Sorry, coming from the world of the hydraulic lifter SBC. Thanks for any info.

Nothing different about the phaser, and since your not going with an aftermarket cam you wont have to open it up to install a phaser limiter. Just line up the marks like a standard cam gear setup. Tq the rockers to 22ftlbs. I spun the engine to get each rocker on the base of the cam before I torqued it. Not sure if it matters but figured it wouldnt hurt.

Thanks man, that's what I was looking for. Figured I'd ask before I tore in to avoid any surprises.

Actually there may be a phasor difference depending on year according to Comp Cam's tech bulletin.

See link below:

I didn't realize there were two cam phasers available overlapping model years, I'll have to give Comp a call asnd see how it could affect my swap. Thanks for the heads up.

Gm changed phasers to change the amount of allowable degree change of the cam I think the newer style wont allow the cam to move as much.

70Chevelle-LS

Well, I'm assuming it would have to be the later type to allow use of the l99 camaro cam. I'll have to try to dig up the VIN, as far as I can tell that's the only way to tell what cam phaser I have - unless someone knows if there were any model specific exceptions or if there is a part number stamped on the phaser itself.

Theres a model number stamped the front face of the phaser. I had to tell TSP which one I had so i'd get the correct phaser limiter.

70Chevelle-LS

Thanks, I hoped there would be a stamped part number. Per Comp's notice:

Original (old style) GM PN 1258994: 2007‐2008 (uses cam core 156‐)
Current (new style) GM PN 12606358: 2007‐2009+ (uses cam core 189‐)

I haven't pulled the cover yet to confirm the stamped part number, but I did find an application list for part # 12606358 (the new style cam actuator) from a GM dealer.

Wonder if you can put the newer phaser in place of the old?

1989GTA

As long as it matches the camshaft. There are two different styles of camshafts and phasers. They each have to match.
