The rods i want to run r 6.7 but i might go 6.536 depending on the price of the pistons between the two. Can you find pistons with a 1.24 ch i need them with at least 10:1 compression with the 6.7 rod i can go with a flat top or small dome. What do you think about running smaller rod journals for more clearance? I can find 2.1 rods and cranks turned down to that, but not sure if its worth it.
