Hi guys thinking about a new engine.im thinking about a ls3 stroker 416.

Heads-tea ls6 243 brand new

Intake-fast 92 ported by tea

Btr lifters

Ported ls6 oil pump.

I have seen 416 with stock ls6 heads and intake pat g cam make 480rwhp thru auto.

Also 416 ai ls6 heads make same power unlocked stall with valve float.

I'm keeping my heads and intake I no there are better heads out there but I have and gonna keep them.with 11.7 cr and pat g cam I feel like I can make at least 500rwhp.its going in a 71 nova street/strip mostly street 4l60e circle d 5c stall.hoping to run 6.50-6.30 on motor 3300lbs.also will I need a vacuum pump.do you guys think my goal is unreal

 

I reused my TFS 215 heads on my 418, and unshrouded the valves to match the .040 Cometic head gasket (11.5 CR). EPS supplied the 234/242/.600/.615 117+2 camshaft that drives 10x better than the 234/242/.600/.610 114 cam that I put up for a year.

The new cam has 4* overlap vs 10* of the old cam, still has stupid bottom end power and has more mid range to top end power due to the earlier exhaust valve opening.

I have BTR Platinum springs with Ti retainers and Yella Terra Ultra Light rockers.

No dyno numbers, but I'm sure I should be ~525 RWHP in my M6 2001 ZO6.
