Was talking to the machinist doing my block today and was asking about getting my rods reamed out to be fitted for bronze bushings since I will be running full floating pins.
My machinist does not recommend the bronze bushings.
What he wants to do is drill a oil hole to lubricate the pins and just slightly hone out the pin bores on the small end of the rod and run the pins bare in the rods.
The machinist said the pins are steel and the rods are steel or cast iron and as long as they have lubricant the steel on steel will wear much better and last longer than the bronze bushings.
As for lubrication I plan to run dry film lubricant on the piston pins anyways.
The machinist says he used to run this setup on his drag boats way back in the day and he sets up alot of small and big block C****'s that way.
I have never heard of running full floating pins and NOT using bushings.
BTW this guy has a good rep and is well known locally. Hes one of those old gearheads who has probably forgotten more than I will ever know.
He is also amused and seems interested in my inline six build.
