I was told by several companies that I called MTI, HPE, Lingenfelter & others that I should never just change rod bolts. The rods need to be re-conditioned for it. Only 1 company and I will not name them since they are a sponsor said "sure why not?"
Well, I logically figure it was stupid to disassemble a motor that far and not just rebuild it, which is something I'm trying to avoid because I want a stroker later on. So I dropped the idea.
Well last week a local friend of mine brought up changing rodbolts and I told him why I was not going to get into, that I just wouldn't turn the car hard. His immediate reply was "go look at what Katech's website says". http://www.katechengines.com/street_...etail.php?id=5
I did, and from what they say, its no big deal with the bolts they sell. Its a simple R&R, torque to 50ft/lb and your done.
What is your input? Has anyone done the swap with Katech rod bolts and nothing else?
Thanks,
Jeff

I ordered mine today. Kind of disappointed of no price break for LS1Tech members
. I need them regardless, so I need to quit whining about it. 
Thanks for everyones input here!

What is the tensile strength of Katech's rod bolts...?
Also...I checked to see if there was any rod distortion with ARP 8740 Wav-Loc bolts compared to the stock bolts...
They both measured out identical to each other...I could not find any difference in the big end what so ever...
Not sure how the ARP Pro's with arp 2000 material would do...
Anybody else do any measuring with any of the above bolts on there builds...?

I did do a comparison with measurments of a Stock bolt and ARP pro series bolt but I have the comparison at home. After measuring I couldn't see a reason why the ARP bolts would put the rod out of round, so I installed them!

What? Are you serious? How much for the rod bolts?
