I have two sets of blower pistons. They are JE pistons with about eighty hours of use, they are in very good condition. They are 4.5" bore, with very usable rings. The JE part number is 181990 for the pistons. They came out of my 540 merlin's, I am going back to naturally aspirated, if you have any questions just shoot me a pm.

Looking for 800.00 for the entire two sets with rings.

I check with the builder and told me I would have to change my othere stuff so I'm out.

understandable, that might be a little excessive

Want to swap rods/pistons and cams?

what condition are your parts in?

10 hrs Diamond pistons and corilla rods. and solid roller cam

We should have just swapped engines, you gave my blowers away.

you are absolutely right, the more I think about what I took for the blowers the more I think I should have made a coffee table out of them. Well, I would trade all but rods, mine are already being match balanced, and I believe they would be too long?

They wouldn't be to long with my pistons...but I'll most likely just sell these engines and start over on a new set of tall deck Darts these are 9.8 decks and are great engines if 632 hp is enough for someone. I'm going on up to 1000 hp and tall decks.
