05GMC4.8

Duration at .050" is 214/218
Lift is .552" intake and exhaust with 1.7 ratio
Lobe separation 113 with 109 intake centerline

This will be going into my denali with at most a 2800-3000 stall.

I am curious cuz i read that the 6.2 heads like a duration split of about 10. So i was thinking something like a 216/226 duration and this recommendation is surprising but im no expert.

Thoughts?

Richard Holdener did a test about this and concluded it really doesn't make that much of a difference.

Run it. It'll make gobs of torque.

Interesting! Do have a link to this test or is it a post on here that i can search? I would love to read about it.

Gobs of torque you say? Just what my heavy pig needs more of!

This is the test i believe madmann26 was referring to for anyone else that may want to read up on it....
