I found the problem. I used the Fel Pro 1250 intake manifold gaskets that I have before. I put on Trick Flow heads and they don't completely cover the rear water port. I pulled the manifold and that was it. Water would pour out of about a 1/8 inch opening on each side. I replaced them with Fel Pro 1262 gaskets.
This was the first rebuild I have tried in 40 or so years. Got the car started today. Needs tuning of course. It is a 306 with a Comp Cam Xtreme Energy cam, Trick Flow heads, RPM Air-Gap with a 600 cfm carb. Also did the 4 sp to 5sp conversion. For anyone interested the drive-train shop shortened the driveshaft , added new u-joints and yoke for $128. That was much less than I thought it would be.
1966 coupe, 306 c.i., Trick Flow heads, comp cam, air-gap manifold, Holley 570, long tube headers, Petronix billet distributor, t-5, Hurst shifter, custom ram air set up.
