Vortec350ss knows whats good.

 

If I were to cam it something 224-227ish on the intake and 235-240 ish exhaust 114lsa adv 3 or tighten up the split and port exhaust runners heavily, pulley up!! If you have the converter to do so it may take a couple to find what the combo likes. But ya see what it does at the track and go from there

 

Yours will be faster. I don't see you needing anything more than the 1b 268mm with your 6 speed.

I'll get a new one with a go pro next time at the track... No more cell phone bullshit lol. In my 11.99 run HPT told me I hit 0-60 in 3.67 seconds. Not bad, but a far cry from what I know other Maggie guys have been able to accomplish. Roger nailed down sub 3 seconds with slicks and a 4l60e. His combo was viscous off the line!!
Lol thanks guys. Too much time spent in my garage and on HPT. Your truck hauls *** too! And damn look at that 60' with a stock converter... Holy crap. Makes me think mine is WAY too loose.

That's exactly why I'd like to see you run your truck before pulling the trigger on a converter. With a shorter first gear in the 6 speed I'd have high hopes.

His heads have an exhaust port bias for sure, but being LS6 they're no where near the newer rectangle port heads. 10* of cam split usually does the trick even with a lot of boost.

That said my 'max effort' specs match yours really damn close!! I think I chose a slightly wider 115 LSA because he could get to a point where the blower is limiting him... More overlap will only speed that process up.
