Lol Ferguson ....I too would like to see what Callie's says regarding the bolts and any documentation that goes with it.

Them simply saying "its OK" doesn't necessarily cut it for me. While I think Callie's makes a great product, I do not consider them God when it comes to rod bolts, especially in their China series of rods. With that being said , I doubt they would use the L19 exclusively in their rods if it was an issue. But, If I had a dollar for every company tech line who's recommendation was bogus, I'd be a rich man, def not a truck driver.

I'm sure you've seen plenty of marine engines that have ingested a bit of water at some point . if the moisture is a problem for those bolts, I'd be worried.

Seems like a lot of the builders use ARP2000, and when those aren't enough, they skip the L19s and go right to the custom age bolts. That is IF the rod can handle them. Which some rods simply can't physically take the additional clamping force needed to take advantage of the better bolts.

Just call Comp Cams and ask them for a cam recommendation on a marine application. I am pretty sure the guy on the other end of the line I got was reading tarot cards.

MT really looking at the info persay Callies view point / tech format info to compared to ARP and other connecting rod suppliers.

I get what your asking. I do not know if the forces are great enough to break that hydrodynamic wedge , but detonation sure will

Or better yet call Merc funny how things have change with the tech help line especially for dealers.

I agree. Lots of rod manufactures making good rods these days. I know Manley stopped using the L19 in their rods, why I don't know. You have oliver, carillo, K1, scat, eagle, Howards, lunati, etc. I wonder what their thoughts on the L19 is? The L19 surely is cost effective with great clamping force and fatigue, just not sure why anyone would use the 2000 bolts since the cost difference is minimal

Have to ask as I know at one time Eagle had some problems and I can not remember 100% but I think it was with crankshafts not rods Correct - is there still problems with their cranks and how about their rods ? .

I'm sure they were thinking they had a brilliant sucker on the phone and wanted to get rid of the l19s they had laying around because nobody uses them. Blew some smoke up his azz to get them off the shelf...

In the beginning you couldn't even bolt an Eagle rod on a crank because they were so out of round. This is not the case anymore. Now there crank journals are all over the place.

I guess these guys should keep quiet also because they are just HVAC guys[ATTACH=CONFIG]533439[/ATTACH][ATTACH=CONFIG]533440[/ATTACH]
