7.3 idi max rpm

[Dave Sponaugle]

Wanna try it on 23 year old rods and bolts?

Just like a walk in the park.

one of the rod cap nuts came off a chevy 350 because i lost one of them. the only difference is the ih nut was a 12 point. so far he has taken this truck to birmingham and back 4 times and he ran it wide open all the way there and back and it just keeps sounding better and better. I did install an aftermarket temp gauge and the highest it ever got was 250 but i think thats because i put it next to the header where the idiot light sensor was. This weekend i changed the thermostat and flushed the coolant. Im anxious to see what it runs at now. Diesel costs too much to test drive it so ill just wait.

There's a Cummins employee with a Cummins RECON (rebuild) in a custom dragster that runs 6K+ rpms but only 1/4 mile at a time. The reciprocating mass is quite a bit more too, I don't know if being an inline 6 is an advantage.
HE KICKS SOME GASSER BUTT TOO.
