New block and rotating assembly are at the machine shop this week, I should have the new motor in by the end of the month.

All things considered....I really like it.
I also run a pretty big cam for a stock cube motor, I thought that there would be some drive-ability issues with the cam and 4000 stall.
It's mild when you need it to be, and when you mash the pedal it runs like a raped ape.

I loved my TH400 at the track. I hated it on the freeway. So much so that I went back to a 6 speed. At the track, I only shaved .20 off my best time with a TH400 vs T56. I was just way more consistant.

The converter bolts that Precision Industries sent were too short....I don't remember exactly but I think they were M 10 x 20 MM long????
