I am having trouble with my 350 backfiring while I am traveling at a constant speed in high gear. What would cause this to happen. I have never had this trouble before.
I believe it to be a small ignition problem, wires, plugs, etc... However, I recently had to have the heads machined on my '88 Blazer. Would this in any way cause this problem or I'm I only paranoid.
