Yeah it's limited by a 1 bar map sensor so that's as quick as it's gone at 3800lbs.. 10.85 126. It runs mid 12's on WasteGate pressure 7psi in the summer heat which is really all I wanted out of the combo from the start. I have a spare engine because we didn't think it would hold much boost but but it's been great. The 4L60 transmission is kind of a limitation also.

Yeah I remember my jaw dropping seeing that run at the track. GLWS Denny!

Thanks!

any mods done to the structure that would hinder you from putting a 305/350 back in it "easily"?

That seems cheap as fuck to me for a body style that is so sought after right now.

His original build thread. Quick skim looks like the heat/ac box was removed, but other than that it looks like the chassis was left alone.

I'm nearing the "part out" price... I welded the new solid engine mounts to the factory K member. To put a V8 back in would just require you to cut off my solid mounts and bolt stock V8 mounts back on the k member. The list of aftermarket parts on this car is long.. I'm open to offers.
