who sells stock size pistons and rods??? I've looked at our sponsors and all they have is for 347's. I'm not looking to do machine work. THanks

Well I think 347 is going to be the cu in. after the hone and cylinder clean up.

i know theres a lil different in size between 346 and 347. I don't want to do any machining.

Then don't build an engine. You're seriously begging for disaster if you're going to build an engine without doing any machining.

???? my stock rods and pistons have been fine they way they are now. just want to upgrade my pistons and rods and i don't wanna spend thousands on a block. i love my current setup and I'm working on a A4->M6 setup so i would like to beef up rods and pistons with the arp bolts and upgrade everything else.

You can't install new rings without a fresh crosshatch. Even a quick ball-hone
will necessitate having the block hot-tanked/cleaned. Do it right the first time
so we don't read another "Uses oil ; What's the cause" thread.....

UGH lol. i know i would need to do a good clean on the block. just didn't want to get a new block. cuz if i do i have to go all out!! and i would change out the whole setup. was trying to stay away from that. I spent 2 yrs building my engine getting the top of the line H/C setup with all the supporting mods at the time. $15k and 2 yrs later i love the setup. 420whp/440wtq unlocked is pretty good on a stock block

You typically can't just swap in parts like that without some machining. You're talking about taking parts from as many as four different manufacturers and expecting everything to fit within a tolerance of maybe +/- .0002"!

The pistons for example, need a specific amount of clearance based on the design of the piston and the intended use. Just swapping in some forged pistons in the bores that were honed in a mass production assembly line for stock cast pistons is probably one of the dumbest things you can do. It's maybe $200 to have the machine shop hone the bores to the size the pistons require and ensure the $600-800 you just invested on pistons and rings don't go to waste.

I hope you were at least planning on balancing the crank...

The answer to You're question about pistons and rods ,,,,,,,,Summit has 3 or 4 brands with cast hypereutectic or forged hypereutectic in stock , .010, .020 , .030 , .040 over for the iron blocks and stock , and whatever oversizes are normal for the aluminum blocks . And they have a few brands of forged rods also .
