Hi Everyone, and thanks in advance for your help.

I'm trying to remove the stock pistons from a 1985 302. I have never dealt with pressed in wrist pins before and I don't know if what I'm looking at makes any sense to me.
It appears, after lookng real close, that there are "2" wrist pins per rod. Each pressed in from either end of the piston and being stopped by a counter bore in the rod. Is this correct, or do I have some kind of alien engine components? Because if this is by design, I might end up being a Chevy lover! (just kidding...NEVER!!).
Please help as I can't figure out how to get these thing out.

Regards......Rick

Interesting. On my 302 the gudgeon pins (one per piston) are press fit into the small end of the conrod. The piston then floats laterally on the pin.

They do take a bit to press them out = I used a piece of round bar. When putting new ones back in you should heat the conrod small end up and work quickly.

Well, thanks for your replies.......

The pin was unusual looking to me as it has a step half way down the ID on both sides. After trying to press the pin out with a 12 ton press and nearly smashing the piston, I figured it was a two piece pin. Anyway....I finally got pissed off and put it in the press not caring if I broke the piston. Using two hands I finally got the pin out. MAN.....those suckers were really in there. But like I said....I have had no experience with press wrist pins. And, quite frankly, will never use them either.

Thanks all.....
