Okay, here are the first shiny bits (again...)

And now: More Rock, less talk... By request from Holland.

More shiny stuff...

I think all of the engine brackets are done now. Unless I find more at the bottom of this pile:

Just touching base - I actually have been working on my car through the winter... I just hate the cold.

Here are before and after photos of the same head. Right now I'm just cleaning - machine work is later.

I think the desert heat (okay, maybe the grease too...) preserved this engine. This is the original engine from my car and while it has issues is in awesome condition as far as cylinder wear.

I have another mule I have been using to test oiling ideas but it is very worn. Here's what I've done:

HV Melling pump with a 90# spring. (Critical to use the Heavy duty oil pump drive - I'm still trying to find a way to run a 5/16 driveshaft..

Drilled and matched the feed galleys to the pickup (like port matching an intake)

Drilled the pasages in the heads to match the pedestals and the rocker shafts.

Radiused the area on the heads the oil feeds into - this normally has a hard edge that sludge will build up on and if the engine ever gets hot it will turn to carbon and block the passages.

Polished the head bolt holes that are used to feed oil to the rocker shafts - I wanted to drill them a little bigger but didn't because just these modifications improved flow to the heads (volume volume volume.)

I have 80 PSI cold at the crank - on a worn engine! And just over 60 psi and plenty of flow at the rocker shafts... I'm happy. Time to apply these to my engine and put it all together!

Sorry for rambling Reijer... 

I just used 10W30 cheap stuff until I hit the numbers I wanted. These engines have marginal upper end circulation like an FE engine. It seems like the same FE engine modifications work to increase the upper end flow without hurting the crankshaft numbers. So far so good. If my numbers on the fresh engine are too high (going into bypass right away) I will replace the spring with a lower pressure one. I like the More rock - less talk thing BTW, I use it when I'm training now... Thanks!
