2013 gt500 vs built 6.0 trans am

[NA_Cobra]

Autos with stalls don't need 4.10 gearing to get around. And a big stall makes an automatic much better from a roll simply because regardless of the speed you will always be right in the meaty part of the power curve due to the higher flash.



What exactly is done to the TA since you seem to know the car? When the OP mentioned a "built 6.0 with big cam heads and stall" it sounded like an all out race engine. If it's a budget build with ported OEM parts then it makes more sense vs. a completely built engine aka forged high compression aftermarket heads intake etc.

Who puts a FAST intake on an ALL-OUT race engine? :shrug:

I don't think the engine is as built as the OP is making it out to be, especially with expections of mid 11s/low 12s.

The OP mentioned the car sounded, "Scary", you could easily take a 24X/24X cam with a 110LSA on a 108 ICL and put it in a stock 346ci Trans AM and make it sound like a pro-stock with it only making 360-370rwhp.

If you're building an All Out race engine, a resonable expectation would be 10s or lower and you definitely wouldn't use a FAST intake over a custom fabbed intake or EFI Carbed intake and you definitely wouldn't be desperate to run a stock '13 Shelby.

Name one person you know that built an ALL OUT race engine (Hi comp heads/pistons ~ 12:1+ comp, custom fabbed intake manifold, etc) to run mid 11s, low 12s?

This is why I think it's just a basic heads/cam setup with LQ9 6.0 swap.
