8" converter on the highway ??

Still a 340? How do you make it survive now? Can you make engine live past 100,000?
Yep still just a 340 no stroker. Best of 11.86 all steel 6 point bar and a Dana 60. Very heavy. I don’t know how many miles are on her but it’s at least 25 years old. All I do is lash the valves, change the oil and plugs. Just took her out for freeze plugs maybe I’ll look it over once.
