High 9s at 650HP. It's no lightweight. I'm surprised you haven't broken it already unless you don't have many runs on it. Just sayin'
If the results don't match the theory, change the theory.

Take it out now, while you can still sell it.

car 60fts 1.30's - 1.40s depending on the track. its a nitrous car also with small 150 shot. so it leaves pretty damn good. we normally run a 10.20 index but wanna turn it up and go to a faster class just trying to see if the rear end should go or can we still beat on it. seems like it needs to go

My Son has 3 years on the 4.10's in his 8 3/4 that were set up by Tim Bowman of Bowman Performance. It ran 10'0's for awhile with my 408 and now 6.54 (10.20-10.30's) with his stock crank 360. Its a 727 with trans-brake car. Since our class now runs 1/8 mile at every track he may step up to a 4.56 gear for 2019. It leaves pretty hard.
