P73 PR3 or P30 pistons?

he never aksed a question about rods :shrug: . it didn’t matter in this case anyway as the pr4’s, pr3’s and p30’s all share the same wrist pin.

hmm… looks like he asked about rods right there

also for to answer his crank question… he can either use ITR/GSR rods and itr/gsr crank in LS block or he can keep his LS rods and LS crank (second choice is best bet) you cant mix and match

edit:
the b18 series blocks and b20b/z blocks have same deck hight… meaning you can interchange the internals between any of them (well the b20 has 84mm pistons so cant interchange them :wink: ) the b16 and b17 have the same block, just different internals … same deal applies… u can put b16 internals in the b17 block and visa versa… altho if u go with b16 internals in b17 block, u got a b16, not a b17 :wink:

whoops, accept my apologies. i’m blind today :bawl:

LOL np, i missed the part about the crank didnt see that till i read it a second time :wink:
