Should I "Retard" my cam...
Should I "Retard" my cam... I am degreeing my cam and had a question on whether or not I should retard my cam or install straight up. Right now I have it degreed straight up and it is spot on what the cam card says. The only reason I'm asking is because I just ordered an S60 with 4.10 gears and was curious if I should shift the power a little more to the top due to the gearing? Just curious on what effects this might have on my setup and is it worth it. I know there is probably not one great answer, but any help would be appreciated?
Here's what I have:
LS1/T56, Stock 346 bottom end, 243 heads(hand ported), 230/238 - 600/603 112+3 cam, LS6 intake, long tube headers.

But, assuming I have good PTV, is retarding the cam say 4* going to make a big enough difference to notice. I really don't know what effects each degree of retarding the cam has on the power and at what RPM range would it take effect.
No haven't checked PTV. We thought about that last night. I guess I should throw a head on and check it.

It'll soften up the low end power and add more up top. I had my cam with a 235 intake duration on a 109ICL in my LS1, which will be similar as far as the IVC goes to what you're doing, and it did seem a little soft at lower RPM, but it was still fun. If it's going to see a lot of street miles, I'd leave it alone. Low RPM power in my opinion, is what makes a street car fun to drive.
Thanks for the input!
Right now you're a 109 ICL, and with a mid 230's duration...that's a good combo IMO! My worry would be if you retard it, it will be too much of a dog with that much duration

But thanks for the advice guys. I think I will just leave it straight up. It does have advance built in, and I don't want to end up with unused power above my target RPM range. I also don't want to end up regretting it if I retard it, and from the opinions it sounds like leaving it is the best situation.
Thanks
