Proline piston warning

[Woodslasher]

I was assembling an 056 with a 54mm top end, and I had a Proline piston on the bench that I was going to install. I had bought an 056 Mag II piston from them a few years back and it seemed to be close to oem quality. This one was packaged differently and had a bit of casting flash, which I cleaned up. When I went to install it, however, it has a good 2-3mm of side to side play on the rod and it is unusable. When I looked at the box, the Proline label is slapped over a generic "white box" label, similar to the ones you see on LRB piston boxes. I will be doing what I should have done in the first place and ordering a piston from The Duke, but I wanted to give y'all a heads up about this issue first.

Had a similar issue with a 350 a while back... Piston was good otherwise but saw had a rattle as the connecting rod floated excessively & contacted the counterweights. Made shims up for it which worked but have never been confident with that as a fix so haven't really run it much

beware of their carb kits being only half of the needed parts or incorrectly stamp cut

Thanks for heads up.

Good heads-up, thanks!! Is Duke still considered kinda 'gold standard for aftermarket'?

Got a white box piston like that a while back- into the recycle bin, I'm always amazed at the good stuff and garbage we have to sift through,- usually go Meteor which are good but it was one I didn't have in stock,- soon got a good quality one.
