as far as i know the 4.3 is a v6 which is actually based off of the 5.7. gm just cut 2 cylindars off if there is a difference it will be the heat range on the plugs
for your info, the Chevy 4.3 ltr in a 94-96 caprice is a 265 v-8, do some research before giving info on engines you know nothing about. oh and by the way, the power rating in a stock 4.3 v8 is higher than a stock 5.0 and also the correct answer is NO, the spark plugs are no different than the 305 or the 350.

The 1991 350 cubic and Chevrolet engine spark plug gap is .027. Most spark plugs will come pre-gapped from the manufacturer.
A distributor sends electric (from ignition coil) to the spark plugs via the spark plug wires, which in turn fire the engine.
It is screewed into the driver's side head between the first two spark plugs up front.

Check/replace the spark plugs and wires. If you're not going to replace the plugs make sure the gap is correct (should be either .040 or .060) and make sure the plugs are clean of oil or gas. If it still backfires after you replace the plugs/wires check the distributor and the timing.
I had the same problem, replaced coil packs,wires. Its the crank sensor, it controls the spark to the packs. Its about 20 plus dollars. Its easy to replace. Greg
