I have had nothing but trouble with my '38 Pick-up since returning from Bonneville. Here's the sitch.... Idles fine Revs fine Sounds fine But when I take off it keeps backfiring! If I stomp on it it doesn't do it though. I have changed the plugs,points,condensor,rotor,cap,vac advance,and the coil. The timing is right,dwell is right,idle is right...I just can't figure it out. It has a '59 Chevy 283 Fuelie motor,Edelbrock 600(man choke). I'm about ready to just drop it off at my friends shop,but I HATE PAYING SOMEONE TO FIX MY CARS!!!! ANY suggestions would be HIGHLY appreciated.
