I wouldn't mix rods, weight could be several grams different

that's what I was thinking. didn't want to mix them up. I cant seem to find them anywhere though....I called my local gm dealer and he didn't really know crap. said he could get a rod for 7.4 which I believe is the same but didn't have a picture to tell me if its a dimple rod or not. are the dimple rods a factory thing or??

What size rod bolts ? How old is your engine ? I have used that rod several times in the last two years to replace 502 rods and as far as I remember it was identical.

I just looked in my 0ld 2005 GM book and I think the rod you want is 10198922 but I dont think it is available anymore unless you can find someone that has one on E-bay etc. Jegs says they can ship it but Summit says not available. More than likely the other number is the replacement.

Yes the 10198922 is what I have now. I see the discontinued them. the replacement looks a little different though. think its ok to replace just one rod with the new style? any kind of weight issues?

my rod bolts now are 7/16" and when I ran the numbers on the motor it came up as 96+ gen 6 I believe.

I've got a complete set out of my running 525sc with the pistons still attached...I'm make you a deal on all of them if you're interested PM me

I believe the GM rods are made in China now, if you're going that route you might want to look at the Scat 4340,

pm me your address,i have plenty of good takeouts.i will send one usps,just send me whatever it cost to ship it to you.add in,i believe teague sells new takeouts for 25 bucks each if you are worried about useing a used one.

I bought a set of 8 rods and pistons from him for 2 bones. Only used 2 of them so i have a few good take out rod and piston complete assy if needed also
