Oldsmobile diesels have 6inch rods, but after you pay the money to get them re-done you could buy a set of scat or eagle rods

As posted above the OLDS 6" rod will work with a bunch of work,and I agree they are not worth the trouble.

I think the rods you are refering to are out of the 265 LT-1 (yep thats a 4.3) in the late model capreice and some impala's, and they are 5.940 not 6.00.

you can use them with a 6" piston, but I dont think they are worth the trouble either.You will either have to offset grind the crank(stroke it),cut a bunch off the deck, or both to get the piston anywhere close to the top....and by the time you pay for all that machine work,plus get the rods resized, you could buy a decent set of NEW 6" rods. JMHO

One thing about the rod you want to use is chevy had problems with them staying on the inside. Either the factory balance job was real bad or they are just junk production rods. I don't think it was an oiling problem, they oil the same as there big brother. Just 2cents worth of advice, choose something you can rely on if your going to race the engine. sleepy

Also I seen on another post you want to use NASCAR pistons?? You do know that they are NOT 23 degree pistons, they are in the range of about 12 degrees (valve angle). That could be a big problem if you run over .500 valve lift cam, You could however have them flycut to the right angle,But there again more money and they may end up pretty thin on top when your done. sleepy

Ive bought a motor with cup je pistons, they had to have intake valve pocket cut, the small dome fits vortecs, though, I think they were 18 degree, about 1998 vintage.

the kicker is in the rings, now that im going to freshen it.

.043 shallow groove also.
je said about 300 bucks for the set, I need to get them measured to be exactly sure what I need.

according to je the new cup stuff is even thiner and more expensive.

Make sure the top ring isn't a 1.2mm. That ring was the most common one used back then, if the pistons are dated back that far.
