So I bought a good used block from a friend of mine, it had been rebuilt and put in a TF, my friend is a purist and pulled the engine for his B and to put the proper TF engine back in his car but then sold the engine to me.
I know the block is good. Great oil pressure, good sound, no issues there.
Here is where the problems do come in and I will try to give as much information as possible but I am at a point where I am racking my brain.
So in order to make sure I have no more challenges with my 1980 B, I have really taken my time and not cut any corners. All the wiring is new in the car and EVERYTHING electrical works properly. The distributor was recently rebuilt by Jeff at Advance so I know it is good. Same goes for the HS4 SU carbs, they have been rebuilt recently and are good. They have also been synchronized and adjusted in from what we can tell is properly. Also the valves were just adjusted too.
The car starts and idles just fine, temp. is now better than perfect (this was not the case until recently and I will go back and elaborate.) The timing was set just as the manual says at 10 degrees at 1500PRM.
When my previous engine gave out a hole was blown in my resonator (or front muffler) and I have not had the car run well enough for me to get it to a shop to get that fixed. I don't know if that could be affecting my running, I'm sure someone will let me know.
Anyway, when I test drive the car around the block, pick up is decent until the the throttle is opened wider, then I can hear and feel a lot of hesitation and inconsistency. What I hear comes out as a popping noise from the resonator and what I feel is the car trying to die.
One thing that is important is that we were having an issue with air trapped in the cooling system and the car getting hotter. After a few times of the needle moving into the hot range, we did a lot of investigating and found out the thermostat was stuck shut. I am wondering if I have a bad head gasket now over this, although aside from running issues when the throttle is fully opened, I don't notice any of the other "obvious" head gasket symptoms.
I am wondering if there are any thoughts or ideas or anything else I should check. If there is anything else that needs clarification, please let me know.
