S52 rods are pretty light, strong and at least they used to be cheap.

Update for this post.
will not be touching/cutting the crank and going with 135 rods and IE Mile pistons.
M52 crank clears my block nicely. They only area where it comes close is the oil return. Not my pic but the crank clears with about 1.2mm clearance there. Should I still grind the block? What # would you recommend as far as crank to block clearance goes?
Andrew's pic. My M52 crank actually clears there with the above mentioned clearance

Any reason to go IE/Mahle vs custom JE for $200 more? Also looks like schrick and dbilas cam is about the same price.. The head has new OEM springs: should I go with dbilas 284/284 or schrick 284/272? I trust schrick but do not know much about dbilas cam.Last edited by zaq123; 01-24-2017, 03:05 AM.
