please don't beat me up to bad for this question but is there a certain direction when installing your piston to the rods.......i do know the big end goes to the crank lol


71 demon stock stroke 440/indy ez-1 running 10.10 @ 132.14 mph in the 1/4 and 6.36 @ 107.46 mph in the 1/8 not in the same weekend but It did it then I sold it.
67 Belvedere that worked it's way in the 10's

if you have valve notches they should tell you how the piston orients to the head, I believe stock have an arrow for the front. the outside of the big end has a 45* that goes towards the counter weight.

It really depends on the piston maker, if they have a dome or valve reliefs, if they have the wrist pin offset and if they have a arrow on them or not Most OEM replacement pistons have a pin offset, one of the old pure stock racing tricks with flat top pistons was to reverse the pistons on the rods and run the offset backwards from the factory way That reduced friction and increased performance as well as made them knock pretty loud, especailly when cold What brand and type(cast, forged, flat top, reverse dome or?)of pistons are you working on? BTW, it does make a difference on some pistons on how they install on the rod as well as how the rods install in the block, make sure you get both correct
