Poor performance/idle
Ford 351 engine. Brother inlaw installed new distributor drove it hard on test run and now won't hardley stay running. Distributor install is correct, plug wires are correct, carb is ok.? Suggestions anyone? My thought is that maybe he dropped a valve and I should do a dry/wet compression test. Thanks

Don't be surprised if a mod moves this to the smallblock forum, but........if he installed a dizzy that was intended for a roller engine, and you've got a hyd. flat cam, the steel dizzy gear will cause serious wear to the drive teeth on the cam, so it won't hold time. The hyd. cam is a cast iron core, and is "softer" than the steel roller. Is it making any new noises since the dizzy R&R? What do your plugs look like?

Perhaps he drove it so hard he stripped the cam gear with the timing chain ?
You need to align everything up mechanically and see what you have.
Also do a timing gear to chain slop test.
Yes just becuase the Truck in question fits the years 73-79 doesn't mean the topic relates to this forum.
Your topic is better for the 335 engine forum.
