Johnny -
I think you nailed it.
I had to do some machining to the Moroso Crank Mandrel (in the Moroso dry sump drive kit) to get my stock crank pulley to seat properly against the balancer, [there's about a .125" lip on the factory pulley that sits inside the balancer, but the Moroso set up sitd flush with the face of the balancer]- after switching to the larger pulley - it stays at a constant 170-180. After getting on it pretty heavy - it ran up to about 192, but after about 2 miles at 70 - it dropped back down to about 170 again.
It seems to follow my oil temp very closely now rather than vice versa before
I went back through all the Moroso, summit. jegs etc etc to see if Moroso made a larger dia (same as stock) crank pulley... the one I have is the largest, which was about 1/2 the size of the stock one. This fixed it !
Thanks for the advise.
You're very welcome! Sometimes I get lucky.....glad I could help
Johnny
