I have finished installing my rebuilt 400 in my bird. It's amazing that the old '72 350 ran at all...the little button([rotor Bushing?]it touches the top of the rotor) inside the dist cap was loose inside the hole which was enlarged and the vacuum advance had a bad diaphram. the button which installs from the top fell out the bottom. Anyway, all new HEI dist now.
It wont start. I have a holly 600 on an ederbrock manifold. I bought the carb re-build about 5 years ago I have two leaks where the adjustment screws are on top. my old fuel pump only had 2 connection points, from the tank and to the carb, the replacement pump has a small line that I suppose is a return line. well I don't have a return line to the tank so I capped it(otherwise it spills fuel on the floor). I started thinking perhaps the old one had some sort of bypass for when less fuel is needed and this one doesn't? can I even use this pump? should I test fuel pressure and how do I do that?
As far as not running... I first tried to run it w/open LB manifolds, It shot fire and was jus' too flippin' loud! Even though I plan to replace exhaust with a larger diameter I rigged it up thinking perhaps I need the back pressure and if not at least I could hear. now it backfires through the carb with a puff of blue smoke. I rechecked the firing order on the wires and they are correct. The motor came back at TDC and I installed the new Dist. with the rotor pointing at #1 cylinder. I think I will re-check to make sure they indeed did set it to TDC on compression stroke and reinstall the dist. Any advice, ideas, or information is appreciated.
