Workin on the Dart "The thread"

[68 HEMI GTS]

?

One of the differences between a wedge and a Hemi Block is the Hemi Has oil returns in the lower corners of the deck that drain the heads. Normally they are open into the crank case. There’s nothing to direct the oil. I’m trying to get it past the reciprocating assembly using these copper tubes I bent up. I drilled and reamed the lower part of the hole so they slip in. I’ll then clamp them down by the pan rail.

With the effort you put into it,why not enlarge the entire drainback and use a larger diameter tube?

Block is too damn hard, I’d be afraid of breaking a bit off trying to hand drill it. Plus it seemed sufficient, I never had any oiling issues. I just want to aliviate additional windage.

SWEET!!!!

I sure am making a career out of this thing. Decided to pushrod oil the top end. Worked with the guys at best machine, they seemed to have it figured out. They bushed the block and ordered me their spec lifters. I have a 500 inch motor I’m building for my dad’s dart first, then I’ll get back in the Hemi. All that of course after I move.

After a few year hiatus I’m back after it. Did a few Mach ups to get things situated. In a good spot to assemble it now.

Also had the deck lid re-shot, the paint was shrunk and screwed up.

Is that a special coating on the bearings?

yes, they are calico coated.

Funny I was thinking today when driving, should a guy choose bearings with the thought of using traditional or Synthetic?
Are there things specific to using one or the other? Like maybe using full groove bearings with standard oil and no groove with syn.? Just thinking out loud....

Did you have to adjust your clearances much with the coated bearings?

I had coated bearings with the last crank so I already had the mains opened up. I had to 1/2 shell the rods to get what I wanted for clearance with the coated bearings.

MEGA BLOCK ??

"New" (2019 redux) Bill Mitchell Products aluminum RB block. The machine shop just got it a couple of weeks ago, and I requested a few pictures (for motivation).
