Default timing set / cam timing question

i have an 01 zo6 wih prc heads and a 236/240 111 lsa cam, put down 416 at the wheels. the car has headers, no cats, and b&b bullets, vararam intake. other than that its stock. my tuner thinks i put my cam in a few degrees retarted because the powerband is coming in late. i need to put in an adjustable timing set and degree the cam into 111 degrees. i was reading about the cloyes hed adjustable set. does anyone have a part # for that or a link? is that just a replacement timing set that won't need any spacers?

also, lets say for example that my cam is in at 114 degrees. when i put on this adj timing set and degree the cam in at 111 degrees, will my car sound different as far as idle quality? being the cam wont change the the timing ?


just found this one on lmperformance

any thoughts?

That set is the Comp 3153KT, which is the Cloyes hex-adjust. It does not come with the Torrington bearing unless that set has finally been released. They were working on it last year. The Comp 3153KT is the exact same set as the Cloyes and comes with the LS2 timing chain. The ultimate chain was the Cloyes IRL, and SDPC recently contacted Cloyes and bought the remaining chains. They are no longer made and were the best single LS1 chain ever made. Second in chain would be the Katech JWIS chain. Don't confuse this with other JWIS or IWIS chains, they are not all made to the same standard even though the German company IWIS Kettenden makes them all.

Confused? LPE had the Cloyes and is a site sponsor. I also bought my Cloyes with the IRL chain from them.

Do you have the cam card, or know for sure it was ground straight-up with no advance?

Just because the LSA is 111, doesn't necessarily mean that's what ICL should be set at.
And even if it is straight up with a 111 ICL, if you can get away with it, you may wish to advance it a touch more, and shoot for 108-109 ICL.

But for sure watch your p/v clearance...advancing it will negatively affect intake valve clearance, which I'm guessing is already pretty tight with that much duration.

i don't have the cam card with me, the tuer/cam grinder does. i'm pretty certain its 114+3. we put it in dot to dot as close as we could get it but the dyno shows the power band coming in late and pulling up too high,

I'm confused. First post is 111 and last post is 114+3. I don't see any huge issue with where the hp is peaking, looks to be about 6,400 RPM.
