Alright, here's an update. I got everything sorted out with the heater core, valvetrain noise, and the rear end. I repainted the whole cowl and it looks great, but I'm too lazy to take pics right now. I set the alignment to zero toe, -1.5 camber, and 4.2 caster. That should work decent for a street car. I initially had it to -2 camber and 5 caster, but I didn't like how it steered. I put the hood on a couple days ago. I still need to do a few more adjustments to align it right. I also got my new interior pieces from NOS4GN and they are NICE! I have new seat covers with all exclusive material, visors, carpet, floor mats, upper foor panels, and T Top plastic. I still need to work out whether I'm going to replace the lower door panels yet, make a new headliner, recover the steering wheel, and get a new trim ring. Right now I'm saving up for tires and weatherstripping. The weatherstripping will go on whenever I decide to start working on paint and body. Hopefully I'll get this thing registered in the next few weeks and work on getting the motor dialed in once I put some miles on it. Unfortunately I found out that my AC compressor is bad after charging the system today. It works, but it is just weak. I'm going to try to live without it until next spring.
Here is one pic my sister took after I gave my brother-in-law a ride around the block. It's amazing that this thing is quicker with 10psi of boost and 1/4 throttle than it was with 17psi and WOT on the stock motor. I can't wait to get some meth in it and turn up the wick!.
