Im new to this forum and SBC work. I have a 1983 K30 1ton camper special with a flat bed. It was my dads old truck sat in the woods for 20years till I came along and towed that 20year old air still in the tires 20miles home. I pulled the plugs lubed and cleaned engine bay. Then i got her to fire up just didn't wanna stay running. Ive done a lot of things to it besides just save the money and get a clean good carb/rebuild old. The problem I have now is I had to re-wire entire engine bay after days of reading I think its correct I got it to kinda run month or 2 ago. Now I got it to idle after a while and pulled it into my shop, wouldnt start after that my dad told me to pull distro and check that and timing (wish i never would have) now ive having issues with timing i've set TDC and droped it in done that correctly I think but still have old dirty carbs and it'll crank snort and shot fire balls out the carb. I lack most my arm hair because of dad cranking it over while a bottle of whiskey down and half def, ill live. Just wish I could get this thing to go again. Any help anyone? Im going to either save the money or get rebuild kit for the quad soon. Also this truck has a 1967 327 vet engine with aggressive cam and maybe 750 miles. I pulled the oil pan and **** i wanted to eat my dinner off it... if my shop was a space ship.
Thanks for any help in advance!
Will post pics of what I have done so far when I upload

Have you got it running or trying to get it running?
You could be off 180 degrees and it’s trying to fire on #6 instead of #1.

And it’s definitely not a 327. There were no 327’s built with 4 bolt mains.

Its absolutely not timed right, don't worry about the carb since it does run until you time it correctly. A bad carb will not back fire through the carb, it back fires through the carb because there is a spark in the cylinder when a intake valve is open.

Here is how to time it without really knowing what your doing....

1. Remove plug 1, drivers side front plug

2. Place your finger in the plug hole and have someone slowly turn over the engine by hand (clockwise) until you feel pressure, continue turning until the timing marks line up, 15 or so degrees Before TDC

3. Remove distributor cap and determine where rotor is pointing...this is your number 1 position

4. Rewire cap plug wires from the determined 1 position

Fire the motor up and enjoy....
