Just wanted to post an update to this thread. The 0.220" total clearance between the small end of the rod and the inner part of the piston has been working just fine with no machining necessary. You really only need to machine the small end of the rod if there isn't a lot of clearance between the small end and the piston. Already have several thousand miles on this motor and no real issues. If I had to do it again, I'd probably go with some Callies LSx-specific rods, since these suckers are heavy. Every now and then I get people sarcastically saying something about using SBC rods in my build... I just remind them that it's been working fine and ask them how their stock shortblock is doing.

Thanks for some real world experience.

what piston did you use with this setup? do you have a part number?

This seems like a decent idea as wouldn't SBC rods be much cheaper than LS rods? seems like ls rotating assemblies are expensive.

Provided you can find pistons with the correct compression height for your combination. If you have to go with custom pistons, you'll end up paying much more in the end.

I found a deal on a set of Diamond Racing 11503 pistons that had been sitting new in box under someones bed for about a year. Worked perfectly.

I wouldn't be able to sleep with a set of Diamond forgings underneath my bed. It would be like Viagra...I would have to call a doctor after having an erection for more than 4 hours.

custom pistons don't cost that much if you are building a custom rotating assembly .I would see custom pistons sets for $750 years ago.

I have the same rods with 6125.BS on them are these Eagle H Beam rods
