Here's a video of the startup on 8-30-15. It's a Butler 467 cu. in. rotating assy. in a 1972 455 block with Lunati Voodoo hydraulic roller cam, Edlebrock round-port heads, Doug's headers, MSD, Champion aluminum radiator, Flexcool '69 water pump, TH400.
We're running a '66 Tripower on the repro '66 intake. Startup was done with the center carb only--end carb locations blocked off.
Engine fired on first revolution. We set initial timing to 16 degrees with 34 degrees total. Idles well at 750 rpm.
The outlet line on the heater core solder joint failed so we took the core out and re-soldered the line. The factory solder joint was not good, but we got good flow and it's now secure. Not too bad a job without front fenders!
I'll post more pictures when we mount the other carbs.
