MP 2.51" stroker crank - 12/28/08 07:38 PM
I'd like to hear from anyone here who has used the 2.51" Mopar Performance S/B stroker crank and whether you had or did notch the block at all for rod clearance (using stock S/B rods).
Thanks,

EM check that # again. Stock 318/340 stroke is 3.31"

The crank stroke is correct at 2.51".
It was my understanding the the mating Wiseco pistons for this set-up have the wrist-pin centerline moved downward to compensate for the added stroke at TDC, therefore allowing stock rods to be used. Maybe this is an incorrect assumption.

how about a 3.51 stroke crank?
a 360 has a stroke of 3.58 and stock rod fit with no added clearance...H beam rods fit with no added clearance...

Correct. Duh. I was too focused on the .51" that I didn't realize I screwed-up the first number. Thanks for correcting me!
