thanks for all the suggestions. i think it was just the hoses are old. new ones will be in thursday.parts house never seems to have what you need lol.will check and see if they have that pressure tester also just to be sure.

If this block was ever sleeved it could have a leak around sleeve. If engine was hot tanked during rebuild ,the caustic acid can eat away at epoxy on sleeve. Had this happen once. Itwas hard to find. Sounds like old hoses to me though. Make sure you have a spring in the lower hose to prevent it from collapsing from suction.

Only time I have seen guys run a spring in a hose is with the cheap rubber hoses and that was 20 years ago. Run a ribbed hose and you not have a problem. Ribbed hoses have the spring built inside the rubber. Besides....the internal spring only helps the hose to keep from collapsing.....does nothing to keep it from swelling. Ribbed hoses will also slow the water some and help with cooling.

No matter what you do....anytime an engine is shut off after a race....it will gain 20-30 degrees because there is nothing to cool the engine.

NAPA had a dyed block check solution, you put it in a like a turkey Baster type syringe that has a rubber cazootska that actually sniffs the air in the top of the radiator while running and warm.

It pulls the sample of air through the dye solution, if it changes color from blue to green, you have combustion gasses in your cooling system.

Not really expensive either
