Default 6.0 Swap is in!!

The 6.0 swap is in and what a hell of a difference. Errrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr rrrrrrrrrrrrrrrrrrrrr!
The KB previously supported 8lbs of boost but now only can flow 4lbs for the same pulley. There appears to be some boost bleed off with this cam. Also of course the 317 heads flow better. I would like to have tried the GT7 Cam, however no regrets with the Comp Cam. Still Excellent setup. thanks for all you help LStech! For all considering the 6.0 ....do it! You will not be disapointed!

You are seeing less boost because you have more cylinder to fill up now. I doubt that the comp cam made that much difference in boost. Its going to take more air to get back to 8psi, so its time to order a smaller pulley.

Thats one of the nice things about turbos you don't have to worry about.

I agree, no pulleys and no having to turn a compressor.

The pulley for my KB is 3 7/8. It is a twin screw SC. Looks like it is time to order the 3 1/2.

Pulley is ordered. Since the engine is brand new, Ive had to break it in gently. So far at 50% throttle and reading the Autotap time stamps 0-60 is 7.0 seconds. Cant wait to go WOT. This engine absolutely screams. There's no regret putting the cam in too. Also there is very little sewing machine sound dispite the 918 springs.

when you put the cam in did you have a idel issue, or did you have it tuned to run the cam?
