Need Help On A Part Number

[71ChallengeHer]

I hope someone can help. I need the part# for a 71 318 pistons. I don't want Keith Black pistons. Any help would be appreciated. Thanks

Chrysler numbers
standard 3420222
.020 o/s 3420220
Low compression:
std 3004513
.005 o/s 3004514
.020 o/s 3004515
why the different listings???  Don't know, but that is what is in the book.
The first number crosses at NAPA ex: 3420222 = SEPW285 $19.49 ea
Hope that helps

Thanks    You wouldn't have the # for .030 ? Thanks I appreciate the help.

Interestingly enough, the Mopar parts book does not list a .030.  1969 .040 is 3004512
Nothing listed in 72 either.
If you go to www.NAPAONLINE.com and click advanced search, yes for vehicle, then "piston" and if it asks, shop online.  You'll see all the options.

OK ?
Whats the "problem" with the KB Pistons ?

DO NOT believe alot of what you hear ? if that is the case ?

I use them REGULARILY, on Sprint Car Package Engines, up around 550 hp with NO PROBLEMS whatsoever !

YES, they require proper fitting !
YES, they require proper Ringend Gap filing !
NO, they do NOT like a lousy Engine TUNE !
however,
99% of any problems you have heard about them, relate DIRECTLY back to user ERROR,
NOT,
The KB Pistons.
