You dont need full free floating, As long as the Piston Rotates about the pin, then youre fine. stock honda rods arent ment to have floating pins.

I got my whole LS engine as a trade for a 1976 MGB (A ugly as ---- british car)

Anyway, You can buy LS rods off HT for $100-150, you can get Vitara pistons from Tom (FJT) on HT for $130 shipped

Be prepared to have a loud *** engine, This setup sounds like a mild case of valve ticking, I got worried that something is wrong but Tom told me that all these setups do that. Pretty neat setop, I hope you know someone in a machine shop to make the bronze bushings.

Whatchu talkin bout, Willis?

Arias can machine the groove into your existing piston for use with circlips/spiralocs. $11/piston. Keep in mind, some pistons might not have enough "meat" after you cut the groove and shorten the wrist pin to suit - use your head.

Standard size Vitaras in a standard size Honduh bore seems to leave a lot of guys with excessive piston-bore clearances = rattle. Honing in a set of oversized Vitaras should take care of that.

Onlinemetals.com has 1" 655 silicon bronze for $36/foot. How much was Crower slinging you for $60?

edit:

"Try MSC Direct or Travers Tool or J & L Industrial Supply. Not to mention
that I would be more inclined to use aluminium bronze (Ampco) than silicon
bronze."

"Yeh. If you're running LOTS of boost, use M-50 or 51 tool steel for the
bushings (hardened to about RC-60) and nitralloy with about a .025 thick
RC-70 (nitrided) case on it for the pins---

I PROMISE the rods would do an el-foldo before you ever hammered out the
bushings !! :-)

And, NO, that pairing is no more likely to gall than hard chrome on
Al-Bronze, it's an excellent bearing pair, commonly used in, um, 'extreme'
environments, such as pressure worms on injection molding machines---"

I just went through this, bought the PM6 bearings from Autohausaz.com. After milling the rod, the A6 bearing was offset due to the line up tang and didn't fit. Paul (my machinist, also assembling the bottom end) ordered a set of LS rod bearings which *were* a different part number and everything is happy.

I'm wondering if I wasn't given the wrong rods - oil hole on the PM6 bearings that weren't used didn't line up precisely. Might be some confusion on my end, just thought I'd update.
