*P4876970 340/360 4.030" 3.31" 6.123" 10.5 Flat

3.31 stroke fits a 340 block...the standard bore 340 is 4.040...these are 4.030

these pistons will not fit a 340....to fit a 360...they are set up for a 3.31 stroke crank...

the standard 360 crank is 3.58........these are some of the MP pistons that were made that do not really fit anything ...

what are you building?

Oh man, i now feel stupid LOL...thank you for pointing this out for me, there is no option for a 3.58 stroke, and thats what im building, a stock stroke 360...well looks like back to the drawing board with the sealed power/speed pro stuff lol...not a fan of the catalog (or lack thereof) on their website, and i hate going by summit racing only

thanks for the headsup man!!!:-D
