LBZ rods

Thanks Josh..I was curious about that.

The LBZ piston looks considerably shorter.

LB7 pistons will go on an LBZ rod without modifying anything. The rod ends are the same dimensions and pin diameters are the same. LBZ wrist pins are the same diameter but longer than LB7/LLY wrist pins.

How much longer are the wristpins?

So could lbz rods go in a lb7 motor? And if not why?

yes they can go in a lb7 motor thats primarily what this thread is about !

Ok. Just wanted to make sure. There were a lot of posts about using lbz short blocks and using lb7/lly pistons but not so much about using a lb7 short block and just lbz rods. I'd be willing to try a set of lbz rods in my motor if someone has a set. I'm probably going to stick with a single cp3 for quite some time but I'm putting twins on this winter and if the lbz are 10 to 15 percent stronger they could theoretically work for me. And it would be fun to do some testing.

I have a set that just came out of mine due to cracked piston #2.

sounds like were doing the same thing

Might as well give it a shot. It could get expensive if it doesnt work but if it does it could be a nice more affordable alternative for a few people.

How much longer are the wristpins?

LBZ pin length is 3.155".

LB7 pin length is 3.047".

Diameter is 1.358" on both.

From the top of the piston to the bottom of the pin boss on an LBZ piston is 2.938".

Same measurement on an LB7 piston is 2.871".
