ROD BOLTS: ARP or Katech?
ROD BOLTS: ARP or Katech? im doing this with the motor on the stand. motor is a 04 6.0L and has 10K on the clock. i hear the 02+ have updated rod bolts. is it worth it? i hate to spin a bearing after changing the bolts. i have bad luck. ive done some searching and see a lot of people doing it. have a good friend that works at GM and he has done it a handful of times, with zero failures.

They are updated bolts. But if your planning on some real hard hitting mods in the future, or some juice, or possibly boost, then I would definitely swap over to some ARP bolts. If not just stay with your stockers. Good Luck

Verdad Gallardo Katech developed the rod bolts in conjuction with GM for ASA race cars. They are actually designed to go in without the need to resized the rods. This has already been done many times with their bolts, so there should be no problems.

Thunder Racing is a Katech dealer, but they didn't have them in stock when I called. Mine are on order from Guldstrand Motorsports. You can get them direct from Katech, but they are out of stock right now.

Any slight distortion on the large side could chew a bearing in no time at all.

you cant really resize an ls1 rod from what ive read. you have to hone them out and use a special larger OD bearing to fill up the gaps.
while you SHOULD check clearances and such and machine when necessary, i havent seen a single engine failure after installing rod bolts in a running engine.
will it cause more wear on the rod bearings? you bet.
how much? who knows.
there is a local machinist in my area that used to build motors for NASCAR, and now enjoys building engines to fill his time. he said the most he has seen when installing an ARP rod bolt was distorting the the clearance by .005.
thought id share, as ive been asking anyone and everyone these questions.
id go with the katech based on what ive learned.
