CAT forged rods $299 @ 949Racing
great prices if I ever decide to open up the engine. That could get expensive fast though.

Anyone fitted these CAT rods yet?
I am currently int he process of mating them up to a set of Wiseco forged pistons- and having a "little" issue.The new small end rod/pin will go into the small end of the forged rods- but only by gently tapping them in with a rubber hammer.They fit and are tight- but they wont spin /rotate freely within the rod bushing.
On the other had if i compare them to the stock set - the small end rod/pin spins freely within the stock bushing.
I guess my question is- is the I.D of the Forged rod bushing too small, - or is the O.D of the small end rod/pin too big.
and how to overcome it?- i,m not keen on machining out the I.D of the forged rods small end bushing- there,s not a lot of "meat" in there as it is.

OK-I,LL GET THE MACHINE SHOP THAT IS BORING out my block to bring the pin down a little
Actually i tried in the stock small end rod/pin and it is perfect- but its wall thickness /therefore strength will be less- kinda defeats the purpose of fitting stronger rods/pins

I overcame this issue- i cleaned everything with kerosene, then wrapped some scotchbrite around a pen and rubbed/spun it inside the small end bushing, cleaned again with kero- aaaaaand
it worked- wrist pin slides in nicley and spin s freely.
I knew it didnt need much - but how much ,i wasnt sure.
