Would anyone of you lovely fellas have a Wiseco piston list of the 1007 series of Mac pistons i'm reasonably certain these are the pistons that take the large wrist pin if you have this list could you either type out the various sizes or scan me the page needed ............. Oops neally forgot i need the wrist pin listing as well for these pistons

mcbob,
The 1007PS, 1007P1-P6 (standard, +0.010 thru +0.060") pistons use a standard 1/2" diameter wrist pin. They listed at the bottom of the attached fuzzy scan (it's an eye test, sorry).

If you are looking for the 5/8" wrist pin stock class Wiseco pistons, they would be in an earlier year catalog page .. not sure if they are a different part number series than 1007... or not.

Thanks Jeff it's the 5/8" rod i wish to use so thats why i needed the list ..............

OK - found this info in the Number 8 Wiseco catalog (circa 1970 - based on the most current mac motors in there being the MC49C, MC91B and MC101A)

The 5/8" rod/wrist pin was used with the MC70-75-100 and Wiseco 101 pistons (but not the Wiseco 101A piston). The Wiseco 5/8" wrist pin was p/n 575, while the Wiseco 91B & 101A wrist pin was p/n 591.

The 5/8" wrist pin Wiseco 101 "9" port pistons were p/n's 1006PS thru 1006P9 (std thru +0.090 in steps of +0.010)

Thanks again Jeff ................. Bob.

Mc-70s, 75s, 100s, and 1st generation Mc-101s came with 9/16" wrist pins guys.

Tom - thanks for correcting that mistake I carried through this post.
