OTOH, I was able to do the entire conversion in about 8 hours over one weekend rather than have to tear it down, send out the jugs, wait for two weeks, then reassemble. I felt the time factor alone made it best to just buy it all at once from Hammer and get one shipment. I probably could have saved a few bucks on the ignition and gasket set, but not worth the peace of mind to get a complete kit from one vendor. I've read lots of success stories with Hammer's products and mine is one of them, so far.

That was just my decision process.

Now That I understand..
But, I don't operate that way..

True of Any pistons ... they Must be Properly Fitted to the Cylinders.. and I do Not trust very many "shops" to do it Properly... Luckily there is More than one fairly close to me..

My own experience of engine cylinders, pistons and rings is an old car I had was re-bored to a specific size over stock such that off the shelf over size pistons to the same size will just fit.

It is not a case of matching them specifically just knowing that you have taken the correct amount of material out of the bore.

It can be stated any which way round you like but the result is the same.

I have a vehicle with wear in the bores. I measure the wear and then look at a list of pistons available for the engine that will cover the amount of wear.

In my example there is 10 thou of wear and the pistons I find are 20 thou over. I rebore the engine 20 thou over and the pistons fit.

How else do you do it?

Just like that... But... Pistons must be In Hand...and measured carefully then Cylinders Bored Accurately to Match Those Pistons!!!
No Pistons in Hand... No Bore Job here....

Any Shop that does it without the pistons... Is a Hack IMO....

Thanks all! I'm leaning towards the Hammer 1250 kit (1995 small fin cylinders) with the dished pistons and my stock 883 heads. I'm trying to resist the temptation of head work, domed pistons, and wild cams. I'm more focused on torque. I'll keep y'all posted.

You won't be disappointed, good choice.

Did the Hammer swap - easy job. (relatively, anyway)
I cheaped out and got the Ultima ignition - don't, wrong curve - pinging.
Got the Dyna - runs great.

I think getting jugs bored and new pistons will put it up near Hammers cost anyway.
Unless you know a guy that knows a guy.
