Full floating wrist pins

[eddie c]

Wanting to build a street motor for a 1996 350 Chevy LT1 motor. What I
would like to know is what are your thoughts on making the wrist pins
full floating. I have always thought that by doing so that you reduce friction or drag on a rotating assembly. I know that alot of high performance factory motors use full floating set ups. Anyway has anyone
ever tested a motor before and after a full floating set up has been
installed and what results has it shown. I also would like to know your thoughts on which is more reliable full floating or single floating. THANKS ed

Full floating wrist pins are for ease of maintenance and disassembly, there is no performance gain.

With the correct retainers, full floating wrist pins are reliable. I rarely build an engine without full floating wrist pins, since I almost always use an aftermarket connecting rod and a premium piston. I prefer round wire locks, but spirolocks are fine.
