Stuck to the SOHC forums, but got linked here for a video. The just happen to notice your write-up.

Only I won't need pin bushings, 21mm pins will be just fine with stock Honda pistons.

What about if you were to use stock Honda cast pistons with the LS Rods how would that work? I was under the impression from what several machinests told me is that you cannot rebush the small end of the rod, insert a bushing and put in a pressed pin (like stock). The only way you could do it is like how you showed it and run a free floating pin. Stock cast pistons cant run a floating pin, nor can you bore the wrist pin hole out big enough to make a ls pin work on the stock D piston.

Greet write up btw

but honestly, why would you wanna do that... the cast pistons won't hold up to 300hp, bye bye ringlands. but, i'm sure you allready know this :P

also, i didn't mean for ppl to think that they should put their stock pistons back on the rods. the basic idea of going pressfit (.747" ream) after installing the bushings in the rods, was to elininate the fear of the bushings wearing away from being free floating. i didn't realize that was the impression i was giving off.

which is exactly why i wanted to find and went w/ pistons that had floating pins. besides i wanted to see how this holds up and to basically see if i could do it.

thank you Jeff for bringing this to my attention

hehe, I knew that was going to be your first response back too! Some people like me, wanted to try and make ls rods work with stock cast pistons. I had a plan of trying PR3 rods using D15 pistons in a D15 block. I have a ton of b-series rods around, and the pr3 rods are hands down the biggest of the bunch. I think it was more of an experiment to see how well they would work. As far as cast pistons and their limitations, everyone knows that.. But it is possible to maintain 275~300whp on stock pistons if using a very very friendly timing map. I'm just a budget guy, and I really dislike dishing the big bucks out on a set of forged pistons.

Can't really say that i don't blame Jeff on the cheapness part...budget and the whole family life really put a hurtin on a nukka's honda needs But still a very good write-up...keep up the good work. Oh, and would you ever consider "special orders"? Say if i shipped a set of ls rods to ya to be machined (since you've done them already, you know what has to be done)and payed ya for your time and return shipping and other costs? Or ya think it'd still be cheaper getting a set of those nice H-beams from tuner toys?

honestly, you would be better off buying aftermarket as of right now.... as it stands, i can't get any freetime in the toolroom. when i did these rods i was working @ a different place. but if you wanted to order the bushings from www.Crower.com , and send me your "bare" rods, and bushings, i could do that!

basically i just dont have time to get in the lathe, but it's nothing for me to get on the grinder and take off .040" off of a rod, press in the bushings and ream them.... if you're interested let me know via PM or hit me on YIM.
