My take on the oiling system crossover tube for the small block

Well this is where I'm at.. I overlooked that the oil pump I had on there was machined on the underside to clear the ARP main cap bolt.

no big deal I had a buddy make a cut on his mill to my new pump.

So here is the clearance Hughes engines did to the oil pump pick up, theres about a 1/16" to an 1/8" clearance from the rod to the pickup.

unfortunately I'm unable to get that same clearance with the new pump using the same pickup screwed into the same spot. this is seriously like .06 -.07 thousandths of clearance. I'll play around with it some more tomorrow. How much do I really need? LOL...

A oil pump gasket would give you a little more clearance.
