On an lq4 6.0 with 799 heads that had the A.I. 226 cc full CNC port work treatment, 10.8:1 CR with a 226/231 duration cam with .605/.598 lift and 113+4............. if I was to swap in a 227/234 duration cam with .614/.576 lift and 113+2, would there be a gain over 10 rwhp?

I think 10 hp is pushing it but hard to say

Especially through a th400, ya I kind of figured it may be trivial. Thanks for the reply.

Id wager the 226 will make more power.

I like your way of thinking as the 226 cam is in my engine now so I'll leave it in there.

Complete waste of time, effort, and money.

With the 226/231 .605/.598 113+4 cam and the A.I. 226 cc heads, would you think more 1/4 mile accelerating power (not purely a gain at very high rpms) can be gained from heavy milling to gain compression?

OR would a larger cam like the 230/238 .605/.605 114 Advanced Inductions cam make better 1/4 mile and trap mph gains without heavy milling?

If you want to swap cams then I would look into a Low Lash Solid in the 234/242 range.

Id go bigger than both of those cams honestly..

That seems to be the consensus yup, maybe a 230/238 .605/.605 114 cam for better peak power. I just hope 3800-4000 rpm doesn't suffer as my stall is a 3800 stall.

I'd do something like my old 234/242 111+3.

Btw, is that the LJMS Stage 2 Turbo cam you have in there now?

Yup that's exactly it. Gives me a 41.2° IVC Abdc (@0.050). With a 10.8:1 static compression ratio, the dynamic cr should be around 8.49:1.
