429 backfiring at idle
Hi everyone
I have a 73 F100 with a 429 and it was bogging and then backfiring when I would stomp on it. I changed the spark plugs and rebuilt the carb and now that problem seems to have gone away but it doesn't want to idle very good and backfires alot
Anybody have any idea what would cause backfiring while the truck is just sitting and idling??? Could timing have anything to do with it??
I checked the to make sure I didn't get any plug wires crossed and they all look good
also its a 4300 carb and it doesn't have points (it was converted to duraspark)
Thanks for any help

Trino it used to bog down and backfire when I would stomp on it but that seems to be better now it backfires while its just sitting there idling
I have an Edelbrock 600 on my trans am and the cars gonna be off the road for awhile so I was thinking about just bolting it up on the truck and see if it makes any difference
Thanks
