Then you need to decide if you want Chevy rods or Mopar rods. Do you want to run a shelf piston or is it going to be custom? If Chevy rod then how long? What ring pack? How big is the budget? Internal or external balance? Forged or cast crank? How much power do you plan to make and how long do you want it to last?

I have a K-1 in my 408, 2.10" rod journals, Comp Star 6.125" with a .927" pin and a shelf Diamond dish piston. King makes an aluminum main bearing for a 340 but not a 360. I did run Kings on the rods though.

The big end of the rod is smaller, which means less mass and more clearance.

Parts are lighter to, & generally costs will be a HAIR cheaper at least with parts I suggested earlier. You could use a Callies Crank instead of a K1, it's generally about $225-$250 more $ than a K1 4.0"/2.10" crank. Depending on where you buy them. K1 & Callies are only ones offering off shelf 4.0" with GM journals. Several companies offer their off shelf pistons now with the .927" GM pin to work with those Chevy Rod cranks. Diamond was first to offer it...

If going to a steel from a cast, why not wait till you get the extra coin and at least throw a 4.125 in it? I mean, you got a good block in the bag... the cost would be more but dang if Id spend money twice on the same parts made from different materials, Id go bigger.

Let the SBC guys deal with that. (9.025" blocks) SBC rods have WAAAY more selection in lengths and rod journal diameters. They are easier to find, generally cheaper than SBM and the smaller big end requires less clearancing in the block. 5429148-DSCN1758.JPG (64 downloads)
