piston rings

[scampy72]

hey guys wheres the best place to get piston rings for my 440? also im not sure if its stock bore and i dont have a micrometer, so can someone tell me how big across the cylinders should be for stock bore, +30, etc. etc.

one more thing i cant spend too much right now and i plan on tearing down and overhauling when i get the cash anyway, so please dont send me links to piston rings that are like 100 bucks +

thanks

4.320 stock. you can't mearsure the over sizes with out at least a dial caliper. harbour freight has them for a reasonable price. i have a bunch of mopar ring sets for cheap.

harbour freight? i didnt know they carried things like that

also so if i measure with a ruler stock bore should be what like 41/4 in?

when you get one, first measure the bore and piston, before you buy rings.

no

no is a great answer but can you be more specific? i know buy a caliper, in that case quick instructions on how to read one? what would stock bore be? everywhere i look there isnt 4.320 rings so please help. i already have the engine and gaskets and everything to put it together but i know i should put new rings on first so.... also while im at it how about connecting rod bearings?

Rock auto has std 440 rings for about $26. Rod and main bearings are pretty cheap as well. Buy yourself a set of verneer calipers and learn how to read it. Simply throwing rings and bearings in an engine is not the best way, but it can work for a lunk like a mild 440.
If the engine runs now, I would check compression and oil pressure before I ripped it apart. Visual inspection is everything.

Parts and tools cost what they cost. You can't measure with a ruler. You can go buy a cheap vernier and find out, ot bring the block to a shop and give them a 12pk of beer.
A cheap ring set goes from $40-50 on up. I'm guessing you'll also need to buy a flex hone or the new rings wont seat anyway.
