tell that to the guy that owns team envy he is pretty successful for an "hvac guy" lol

L-19 especially I have been taught not to handle them with your bare hands because of the acids from your skin can promote corrosion. FWIW

You can have the strongest rod bolt made but it still requires the importance of proper stretch / torque.

I always thought for rod bolts as the crankshaft rotates the big end of the connecting rod becomes almost oval shaped that's mainly what causes rod bolts to bend. So I always believed rpm had a lot to do with it more so as the rod bolts is the main supporter for all the tension loads caused by each rotation of the crankshaft..

This is the dumbest truck driver I know. Jus sayin.


Speaking of rod bolts, I don't keep my boat in a heated garage mahal. That said, all those spring days that the dew is on your windshield, your engine is sweating on the inside. I don't start my engine everyday and bring it to operating temp everyday. It takes some run time to boil all the water out. That's why short trips in the car are worse than highway miles. L19 sounds like a bad idea anywhere besides a desert. I guess a super stocker or a dragster you are running a filled block with would be ok, but those are easier to put in a temperature controlled garage.

Of course I've never built an engine or been to college for that kind of thing. I've never sat and talked with any drag racers or engine builders. Never met anybody who engineered the 426 hemi or street raced the silver bullet in the 60's. I'm a dodge driver. It would be awesome.

That's what I thought. And it's a real killer when the motor free-revs with no load. That really oblongs the rod. But I guess when you are filling a cylinder with compressed air it is more detrimental than rpm is.

Where does the "CARR" rod bolt that Carillo uses fall in the spectrum?

Big money. High Rpm

Who makes them for Carillo? I'm assuming that "CARR" is short for carillo.

Any down side to using them? I have carillo rods and those are the bolts I have.

Thanks, rob

They use there own bolts. Everything they make is top notch. Ever see there diesel rods? I don't know what they make them out of but it's almost impossible to machine the weights on the end of the rod. They make some bad as stuff. To expensive for my wallet.

My experience comes from drag racing and circle jerks. That being said, I've had great success with ARP 2000's.Myself and a group of drag racer's making 1000hp at the wheels on boosted engines with no failures. To me the question should be who installed a ARP 2000 or (insert aftermarket option) and had a failure??? What horsepower and RPM did it happen??? All the engine failures I've seen are normally from something else. I. e dropped valve, lose of oil pressure (yes possibly from rod stretch) and leanouts.

How long before this thread goes completely off topic? lol
