I also measured the bellhousing runout and it came in less than 2 thousandths. So, should be good there.

Similar issue on my 383 w/ Hedman mid-length headers and AFR heads, had to cut and grind a socket just to be able to remove one of the plugs. Even with fiberglass thermal sleeves around the boot had a couple melt. Also had access issues torquing a couple of the header bolts and found Remflex (https://www.summitracing.com/parts/rfl-2086) headers gaskets as the only way to stop exhaust leaks. PS: Looks super clean.

Went to start the engine on Saturday and had to shim the starter a bit so the pinion would engage the flywheel. After that, it started on the first crank.

Oil pressure was good (about 65 psi cold), but I must've had an air pocket at the intake by the thermostat and water temp sender, because my fan didn't come on and I shut it down due to the temperature rising. There was also a coolant leak at the POS swivel water neck. I've tried vaseline on the O-ring, RTV, and flat sanding the mating surface, still leaks.

I ordered a different water neck that should be in today. Hope to get the timing, idle, and carb tuned and go for a drive soon.

Good job! Glad to hear you're so close.

I always drill a 1/8" hole in thermostat flange to help bleed air out of system. Works like a champ.

Keep up the good work, cant wait to see how you like the first drive.

Thanks guys!

Lance- I did drill a 1/8" hole in the Stant t-stat when I installed the new water neck setup. Seem to do the trick.

I've noticed that with my water temp sender now in the head that my gauge reads about 15-20* higher than when the sender was in the intake. I haven't had any coolant spew out of the radiator, so I don't think the engine's actually too hot. Is that a common temp differential between head and intake placement?

Also, my timing was too advanced initially (fixed last night) and I believe my carb is too rich at this point. Both of which could possibly contribute to higher temp readings as well. I'm going to hook up my AFR gauge this evening and get that sorted.

Just a data point- the water temp sensor in the head was actually reading about 20-30* higher than in the intake.

So, I decided to move that temp sensor to a port on the Vintage Air water neck riser I just got. Now the water temp gauge reads in a "normal" range.

Ready for the first drive this weekend.

Good deal!! Nothing like that first drive...
