I`m probably the guy, in the past that posted about running the pin end , steel on steel w/ no bushing, full floater. I was building a 383 sbc, and I like full floating pins. The machinist that did the work on that block told me it would work, said he`s done it many times. So we tried it and no problems, was probly about 400-450 horse engine. It ran till I sold it ( low 11`s) and built a 406.
