I do not think the current heads, or trans build would tolerate a really hard tune. As is I am worried about the hard parts in the trans and lifting the heads.
Hindsight is a bitch.

Obviously there is a very bold line between mid 9s and high8s, but with a few hundred lbs taken off, a really well setup suspension, some drag wheels and tires, a little more boost, a 1.3ish 60' you might be able to swing for the fences before lifting the heads. Yes you could break something but I was just curious if that's what your end goal was or to just tune it in now and keep it street car. And why not hitch up the LLY and tow it down to md for a track day?

Its neverending
MD is just a hike for me, even towing it there, Cecil is a easier trip cause I can stay over at my folks place in DE.

With 11psi my anti-"LT1 guru" 383 went 137.68mph with stock, unported, stock valved heads. Casting flash was cleaned up on the intake port but no shaping or porting of the ports or chamber. That is it. This was through an M6 at 3860lbs.
