Two things. Why all the sleeves? Also, if you have a machinist asking YOU why you wanna go with floating pins, find another shop. The advantages of floating pins are well known industry wide. They offer great stress relief and actually free up some horsepower. By allowing the piston some more movement than a conventional pressed pin offers, the piston is actually allowed to "rock" in the bore a miniscule amount and relieve some stress. that's why almost every high performance engine from the factory had them. Also, keep in mind too that floating pins will produce a noise. They will make the engine have a knock like a diesel at idle. Nothing to worry about. That's how they work. Again, I cannot stress enough that if your "machinist" questions the use of floating pins, I would be questioning using HIM. Lastly, some shops will try to talk you out of bushings in the small end and just size the rod itself to a float fit with the pin. DON'T do it. You need bronze bushings in the small end.
Oh and that crank price is ridiculous. I get cranks turned all day for 65 bucks.
