Default different style of piston wrist pins.

I bought a 454 for a couple hundred dollar.Didnt know anything about it but saw forged sealed power in the short block.Still had the pan on it so didn't see anything else.When I took it apart it had a h-beam rod and the sealed power pistons didn't have provisions for a spiral lock.They had a wristpin that would float but had some kind of aluminum slugs on the end of the wrist pins.They aren't locked in by any kind of lock just look like the cylinder wall keeps them from coming out.My question would be is this any good and can you put any power to a setup like this.Im planning on boosting it to 550-600hp and just haven't seen this kind of setup before..Opinion are welcome..thanks in advance

They’re called pin buttons and they’re common in blown alcohol builds so have no worries

This article from Wiseco about their buttons is really good and should give you a good grasp on what they are and why they're used. Wiseco makes a specific style that seem like they work fairly well.

Is it "should have" or "should of"?

The phrase should have indicates a missed obligation or opportunity in the past. In informal speech, it is contracted to should've, not "should of." I should have (should've) known you were lying. Tom and Pauline are so selfish, they should have (should've) been there for you.

I love the buttons....Probly cause of hatred for the spirolox. You'll never find one in the oil pan.
