I took my original radiator down to a local (highly recommended radiator shop) to have it cleaned, checked for leaks and pressure tested. Fortunately it passed with flying colors and I didn't need a new core which would have been over $500!
It got a new coat of paint and was installed along with a new battery, the alternator, radiator and heater hoses and new aluminum valve covers and billet breathers which were a birthday present from my wife and son. Filled up the engine and radiator with coolant, put 10 gallons of 100 octane gas in the gas tank, primed the carburetor, hooked up the gas lines and installed new plugs and distributor wires along with a new Summit Electronic ECU and distributor. Unfortunately, when we tried to fire the engine it didn't want to go. Not even a hiccup, backfire, fart, etc. Nothing, it just spun. A check of the systems with some help from the forum members and my mechanic son determined I was not getting any spark out of the distributor. A call to Summit this morning resulted in them sending me out a new Electronic distributor, ECU, etc under warranty. Hopefully, the engine will come to life in a few days. This waiting is killing me.
