Spark plug are new and high performance. Tested for spark with new and old plugs and the spark stays the same. Still gotta change the wires though. Gonna check timing belt first then see about compression tests. Was gonna check timing belt this weekend.

Lots of bad plugs out there these days, with old lines sourcing through China. No belt on a 350. Timing chain, and unless it's a super high mileage engine jumping a tooth is not likely.
