Hi there BuickV8 community, I'm having a issue with my 70 350 I recently rebuilt. There is a loud ticking when I'm driving and is quite will at idle. There is no tick upon start up or once warmed up just upon acceleration, oil pressure is at 40psi cold and 25psi hot drops to 10psi at lights when driven for awhile. Also put a booster plate on oil pump cover, motor broken in as well as primed prior. Headers are pretty beat up and flange is a little tweaked so not sure if that could be case. I don't wanna spend $400+ on a set of new headers right away because if that's not case that's $400+ that could go towards my 455 I'm going to build. Found to bad wires yesterday and replaced all wires plugs are good and gapped as well. So anyone have any ideas. Thank you.
