Not all the 396 375 guys are blowing up
their stuff. Sounds like the ones that are having problems should go see the engine builders of the ones that are not. Or back
The rpm down below 8300 or whatever they are trying to turn them too. Changing cam profile will help valvetrain failure.

I've heard of places that will run a cam and lifters on a special machine that breaks in the lifters to a new cam. Maybe that's an option, even before you run it in an expensive engine. Just a thought. If the parts are broken in properly the tool steel lifters are supposedly very reliable.

I keep beating a dead horse with this suggestion, but go and test some valvetrain parts on a Spintron.

Instead of lobbying for parts to cover up for a lack of understanding of what is going on in your engines valvetrain wise, try to do some research and talk to people that figure things out.

If you live close to Pa go see Ray and Dave Barton. They have a Spintron machine and have worked on all kinds of engine combos. I'm sure they would be able to fix the problems you are having.

Or

Lane Line, Brian Tilburg, Steve Ficcaci, and Darrel Weikle are some guys that build
Very fast and reliable 396 engines that last and win races. Save your money and go see any of the above people.
