525 AWHP at ~22-24 psi on pump gas should be totally doable; at least it's doable with my DR headers + E3's.

I'm with you on Ray/Scott engines. I still go back and forth on my long-term goals, but if I ever plan to push beyond 600 AWHP, I'm getting a 4340 crank and letting Ray do the assembly.

What sort of bell housing damage are we talking about? Unless your trans has been eating synchros on a regular basis, I'd stick with the original bell housing and swap in a new synchro. 1st and 2nd gear are so easy I used to pull the trans, make the synchro swap and have the car running again the same day.

Man, if you've got a 300m 18 spline output shaft, why are you beating yourself up about spline count? Stick with the 18 spline and install your billet t-case housing!

I have a forged crank ready to go in. Not going to try to make this much power on the cast one.

There are a couple of bolt holes that had the ends popped out from too much RTV when this thing was rebuilt in the past. It's holding up, but not without jb-weld One of the long bolts that goes from the end case through the mid and into the bellhousing didn't torque up very well last time when I swapped out my output shaft.

I think I'm going to also put a new third in. I have the new syncro and sometimes I feel some resistance when shifting. I also have to do 5th because it grinds sometimes oddly enough. The other thing is that it is pretty loud in 2nd. Either the 2nd gear needle bearing is going out or the pre-load need to be reset on this thing.

The only reason I was thinking about a 25 spline setup is that if I can part this trans out I can just get a built unit from jackstransmissions and just pay the core charge. Total is $1600 then. If all the parts from my current trans sold I wouldn't be out a huge amount, but no one is buying anything so I'm going to have to rebuild what I got.

Its funny how "rare" getrag parts are, but when you try to sell them there are no takers.
