Well, I can't go to the 2.100 rod bearing for a stroke increase. Not for the full .275 increase anyway. It would move the rod bearing oul holes too far and thin the inside of the crank throw. So i decided to go with a 2.20 bearing and 4.315 stroke instead. Not quite what i wanted but thats life. It will be interesting to see what these changes will do for power. The cubes will be 550.5.
Edit;
I got lucky today. molner makes a Hemi length H beam 6.860 rod with .990 pin and bbc 2.200 rod bearing! With my 1.660 ch pistons, 1/2 of 4.315 stroke = 2.1575 it puts me at .022 in the hole. Cometic makes a .027 thick gasket to fit providing .049 piston to head. Right where i want to be! Rods are on order!

Sounds very tight Is this an "on the edge" drag engine?

This is my last effort to go a bit faster. I assume .049 is plenty of piston to head clearance for steel rods. I had no issues at .045. Compression will be 15.5 to 1. The valvetrain is where the most issues have been.

Wishing you the best of luck,,GET IT!!

Thanks Hemi itis! I just got the specs after the rehone. Had to go out to 4.5043 to get all eight holes clean. Line2line can easily make that up they say. They coat the skirts so only 25 percent of the desired piston to wall clearance is left, then a three step warmup/ cooldown process wears in the coating to proper fit and it gets saturated with oil and is ready to go. Since it needs a full cooldown three times that rules out dynoing the motor. Hopefully this coating will stablize everything and help make more power.

Me thinks the dyno testing would be the perfect way to warm it up and cool it down 3 times very quickly with a electric water pump

Just a guess but i thought they wanted the motor almost room temp each time. I will have to check with L2L, as a dyno session sure would be nice.

All the engine dyno facility I've used have local water supply piped into a tower, the towers have thermostat to set the run temps so you can test it at 220F down to the local water temps coming out of the pipes to the towers
I like to do my pulls between 150F to 180 F, like I race my motors at

Thanks Cab.

Yes i agree with what Cab said about being able to control dyno coolant temperatures. Never had a problem. Also, that is what i was speaking of when i spoke to the maximum safe amount to offset that journal.
