500 CFM Holly 2 barrel. Cut down on the
mill to get rid of the non essential parts.

Should be running in a couple of weeks.

I mostly need to build the new ignitions now.

And wire things up.

Mounting the oil filter on the PSRU adapter
plate worked out well.

One of the many advantages of mounting the filter
on the adapter plate  is you can use a device called
a "pressure gauge in line adapter" to feed engine oil pressure
to the PSRU right out of the filter.

These are quite handy.

Paul, That answers a few questions. My new engine has the very same set up but with fuel injection.  Was worried that the runners were getting too long, but exactly the same, but I do not have the clearance on top as this motor has.  By the way how does the dip stick fit?  Probably just the angle of the photo.

The old dip stick hole was plugged and the oil filler tube was removed.
The oil filler tube hole was converted to a oil system breather.
It is usually quite easy to add a dip stick to the back of the oil pan.

In this case Mike Wills built the oil pan with a rearward extension of about
6 inches. He did this as the pan was wedged shape to get room
for the cooling system diffuser and he needed more volume
in the oil pan. The filler cap is shown in this picture.

You must remove the cap to check the oil level.

Mike did a masterful job of squeezing everything into
a 24 inch wide cowling.

I guess a sight gage could be made from glass tubing
and mounted on the side of the oil pan.

If i ever take the oil pan off (a really big job) I might consider that.

I need a PSRU oil drain back fitting on the front of the oil pan.
As it is now I run the PSRU oil drain line back all the way
to the rear of the oil pan.
