MRL Mild 440

Thats about what I am building all the way down to the ignition, I ordered a new MSD 6 box then changed my mind and am goin to try the Skip White HEI distributor with an MSD Blaster 2 coil. Already have the RPM heads, will be going to the dual plane RPM intake, looks like it will be perfect in that RPM range.
What advantage do you see oiling thru the pushrods? I havent given that any thought. I will be using the heavy slugs TRW 10.5 pistons with Eagle rods, providing they dont weigh more than the rods do LOL.
