So the L26 has the powdered metal versus cast (?) rods of the L36, right?

I imagine that would give the L26 rods a different weight?

So then, is the L26 crankshaft different? (or weighted differently)?

Ultimately, would the flexplates (flywheel) between an L36 and L26 be interchangeable?

yes

OK, here's a question. After digging around some more, I believe I read a post on this very forum stating that the 2005+ Series 3 flexplates (for L32, anyway) are "dual pattern" (i.e., drilled for both 245 and 258 mm torque converter). Can anyone confirm this? And does it apply to L26 also?

Thanks

it seems as only the 9C1 police package impala's have the dual pattern 3 window flexplate i have an 04 9C1 flex that has the 3 windows of the L67 flexplate but has both Tq conv patterns and i've seen/had a couple 04 and one 05 GTP's and none of those had both patterns...
