Another episode of "What will it run?!"

Update...
Hydraulic lifters suck. All 8 of these turds bleed down so bad at the end of a run it sounds like a 12v cummins. Which explains last few times at the track I notice the last 200+ ft of track the car does nothing, doesn't pull anymore. Then sounds like a diesel on the return road.

If you are running a stock oil pan, it's not the lifters fault.
overfill you pan by 1 quart and see if it fixes it!
If it does, buy a oil pan that has oil dams in it. Most aftermarket pan do. or weld one in your stock pan.
It's getting a gulp of air and pissing off the Hyd lifters.

Your new combo looks good to me, BUT you need to add a oil pan to that list.:)

New pan is a kevko with baffles... oil was a qt over full with the other engine, but with a stock style pan without baffles. I figured it might be some form of oil control rearing it's ugly head, I think it's a combo. The lifters don't like over 5500rpm, with the 4.30's it was about 6200 at the stripe. The new duster will have 3.55's in it, she wants to drive it all summer long. The plan is new lifters for the old engine as it's getting swapped and I was thinking about another kevko pan as well.
