its an 8 inch PTC
Flashes right at 5k... its almost a tenth quicker than the 4500 flash 727 convertor i started with... but the car doesn't ET as good with it. Expected to gain going to 904, not slow down.
The 904 convertor has been about 117.50 mph, the 727 convertor went almost 119.
I suspect my current vert is too loose, expecially in high gear.
Going to have it tightened up before i use it behind the 418 that will have way more compression
