Are we talking rear wheel HP ??

Crank hp... Was on an engine dyno.

OK, well all Dynos are not created equal. So there are one's that test lower and some that test higher. Then you have to consider the elevation. I believe you biggest HP problem is an extreme mismatch with the 390 head castings and that camshaft, IMO. As for your oiling problem . . there should be a restrictors inserted. FEs do not oil through the pushrods but ta the shaft rail. The restrictors control the oil flow. Are they installed now??

Dummy me, just realized I was answering an older thread . . so the heads were the problem. I'm glad it's doing better now. How about the oil restrictors?

Correct pushrods now installed along with carb jet to restrict oil.

It's not a pushrod problem. The pushrods don't get the oil to the top. The FE engines have an oil passageway in the head, that fills one rocker shaft support with oil and it comes out the shaft itself. It's not like a small block where the oil is transferred by the pushrod.

I get that FE's don't get oiled through the pushrods... However the first time the engine was built my builder used the incorrect pushrods.. Ones that oil through. After the engine failure these were replaced with the correct pushrods.

You are missing the point I think. Whether he used pushrods with holes in them or not has NOTHING to do with the oiling problem. The oil will not go to the pushrods just because they have an oil hole in them. The oil passageway in the head needs to be restricted to have good oil flow through the engine. It has nothing to do with the pushrods, what he used, nothing. It's a separate thing that I'm afraid you don't fully understand and perhaps, even worse, maybe your builder doesn't understand.
