I know yall have got this kind of question before but i am having a problem with my timing on my 454 bbc. Its the 454 HO out of jegs. Its pretty much a stock 454. it will only run with the timing set around 55 degrees. And with the timing set that high it kills starters and flexplates. the distributor is a mallory hei with full lock out. it has no mechanical advance nor vacume advance. Its out of a race car. Im wanting to know how to get the timing down and making the motor start and run without it backfiring threw my carb or dogging out on take off. if yall have any input please feel free to give me some.:smash:
