Illicit

It was backfiring like gun shots all my neighbors came out of their houses 😂🤙🏽

So I found the problem I feel like such a noob 😂 it was 180 degrees out of rotation in the exhaust stroke not the combustion stroke

I had my wife keep her finger on cyl #1 with spark plug out and found the compression stroke with that method. While I turned the balancer to make extra sure I was on the compression stroke instead of the exhaust stroke. She wouldn’t feel anything if it was the exhaust stroke right?

I have spark, if it was fried wouldn’t there be no spark?

Hi all, I own a 1972 Buick Riviera (455 cui) I recently made a friend who sent me a nice HEI and he walked me through it. And I’ve re done it maybe 20 times. We had no spark at first wich was the pickup coil and I took the distributor apart and rebuilt it with a new pickup coil then I had hood spark. So I have 12volts on start position and after so much research it is impossible to have 12v at crank so, I have 11v or 10v and that is perfect at crank. Next I had rotor pointing at cyl #1 and timing marks at 0 exactly. The spark plug wires are in correct order. I removed the resistor wire from engine back to fuse block and replaced with 10g wire. I have fuel and new spark plugs. The engine cranks and cranks but dosent start it’s been 2 months of trying this and it’s just not starting, everything is timed correct at TDC. I haven’t taken the engine apart so it can’t be combustion/Air. We are completely baffled. I need some help really really bad it’s stressing me out. Appreciate you guys a lot thank you so much!
