Hello all, I am hoping someone on here can help me out. It's my first classic that is all me and I use this forum a bunch to help me build it from top to bottom. I have a 1970 chevelle malibu sedan with a 1974 four bolt main 350 which is attached to a powerglide two speed. That powerglide is actually being replaced with a TH400 once I find a shop that can cut my driveshaft. ANYWAY, the motor has only run once and it died on me in the middle of a field so I rebuilt it, now when turning over I hear faint pops out of the exhaust and sometimes a big backfire, but it doesn't smart. Smells like a firecracker too. I am wondering if any of you have seen this and if you think this is timing or valves or something worse.
I apologize if this is going in the wrong area, I am new to posting to forums as a whole.
Thank you!!
