Hello Vintage auto owners,i have a 1972 Mustang hardtop with stock 62K mile 302,after market Eldelbrock performer intake and new Holley 600 Street Warrior carb.-I also removed the stock single exhaust from the car this past fall and installed long tube headers from Flowtech with the Purple Hornies header mufflers.-The vehicle runs very well /idles fine but when you drive it down the road and hit the gas above 50mph or below the carb pops which i believe might be a timing issue and too much advance.-I performed a full tune-up on car when i rescued the vehicle 2 years ago-Looking to restore the car back to better that staock with maybe adding a set of 351 2V Cleveland heads i had cleaned up @ the local machine here in Newcastle,De. -And freshen-up the engine of course like a street Boss 302.-
-But for now just want to get the engine running correctly with the right timing and no more popping when accelerating.-Thanks for the help- I only put about 100 miles on the car since buying it 2 years ago.-Fresh oil/filter again about 2 months ago.-
