Default Update

Update:
- I R&R intake gasket with Fel-Pro which block the exhaust cross-over.
- I used the "Cooling System Vacuum Purge And Refill Kit" to try to eliminate any air pockets.....it actually worked pretty well.
- I did add the bleed lines to the intake. I drilled a hole in each intake side matching the (blocked) head water ports. Tapped (1/8 NPT) for small hose fittings and connected them with a "T" and then ran it to the gooseneck.
As I mentioned previously the radiator is new; but I have taken it off again and back flushed.....seems to flow fine.

- Results. ( 80+F) ...not much difference.....(I have an in-line radiator cap - no surge tank yet - on order)....I used a "Spill-free-funnel" to be able to monitor it.
- It pushed out about a pint+ or so....it started from about 5 minutes on.
- Also notices very tiny bubbles occasionally....from 15 minutes and even some at 45 minutes.
- I also ran a Strong garage fan on the radiator the whole time....at 40 minutes it was at 195,....when I turned the Fan off for 3 minutes, it went to 210; turned fan back on and it went down to 205.
- When I revved the engine for a minute it would drop a few degrees.

My goal is to keep the mechanical fan, build a better shroud and add two front fans (ERA type). (yes I'm sure the Mark VIII fans would work best).

Next - integrate the expansion/surge tank (and overflow tank);
- Maybe get an undersize water pump pulley.

Again, thanks all!
