30 years old and she is HOT

Hello all. I've waited a very long time to post these pics but I have problems with her.

Yes it is a 76. No that is not the original tail, note the garretson intercooler. I installed those two little goodies after replacing the warn out 3ldz with a K27 with 1 bar spring and upgrading to a GHL exhaust. The internals are 3.0 and just rebuilt (maybe 30 miles). the problem I have is over boost. I am hitting 1.2 bar almost immediately. I tested this with a manual gauge sitting on my lap. I was told to install the .8 bar spring but I dont think thatg will sove my problem. I think the waste gate will still open before I hit wide open throttle.

If this is enough info am I looking at a larger exhaust? if my thinking is correct, the GHL stuff is too small to allow the motor to breathe thereby creating too much boost.? The car was much faster before I had the motor rebuilt along with the rst of the car. Plus I was able to hold the pedal down as long as there was straight road ahead of me.

Thanks for any and all help
