We’ll have to see how it all unfolds, but here’s my take on their quest for 425tq……..

Basically I’m wondering……..just how bad would the current 906’s have to be, that by doing a “better” valve job…….and nothing else……..there will be a 40+ gain in TQ?
I’m highly skeptical of that happening.

I could see the number getting into the 400 range with a proper VJ and suitable amount of bowl and SSR work.
Then slide the Bullet cam back in a couple degrees advanced from where they had it before.
Measure the chambers and get the CR to at least an honest 9.5:1.

That and it would seem he thinks if he sees a top cut the valve is sunk.

It’s hard to follow what he’s doing.

I mean if the torque number is down before I blamed the heads I’d be looking at his tuning.

He’s an all in guy without much of a curve.

Plus I’ve never seen him actually do anything other than change a main jet. Or read a plug.
