Piston on rods tight So I had my pistons put on the rods and two of them are a lot tighter then the others.they move but u can hold the piston up with the rod where as the others go to the side.the machine shop says it's fine but is it really ?

If u have time get them to redo it I had a couple like that but it was down to the wire so I just ran them that way now granted I did not have problems out of it but overall the motor ran good and still is taking nitrous hits but I still wasn't comfortable at first so if u have time make em fix it if it's something I need to be running right now run it the way they are
They should have had the pin bores machined for additional clearance as most all piston manufacturers leave them a bit tight for this reason. To customize
If these are press fit style rods, then you're pretty much stuck as most machine shops will ruin the Pistons trying to get them back apart
If they are full floating with the retaining clips then it's easy to pop them back apart and hone both the rod bushings as well as the piston pin bores
