03-13-2011 04:06 PM 1930u 392 Hemi oil pump conversion
Ran into a few more problems with the Hot Heads oil pump and adapter. The first was oil pan clearance but I was able to shorten the pick tube and screen assembly and got the recommended 3/8" dimension between the pan bottom and the pick up.

I also have a clearance problem with the aluminum oil pan and oil pump and adapter. The oil pump assembly won't allow the oil pan mounting holes to line up with the block rails. The pan needs to move forward in order for the bolt holes to line up. I think, I can take care of this problem by milling .125 off the back of the oil pump housing and the billet adapter. No way am I going to hack up the oil pan. If that doesn't work I'm changing back to a stock 392 oil pump.

I converted the original 392 oil pump to a high performance 360 small block Mopar pump. This is easily done by using the kit from Hot Heads. However, I had some clearance issues with the kit. It comes with a small billet mounting adapter and a step down bushing, or spacer that indexes into the rear main cap. If you're using main studs, nuts and washers be careful of clearance problems. The small spacer is very close to the washer and main nut. I also could not get the spacer to sit flush on the main cap. I had to trim .020" off the spacer in order to get it to flush out with the main cap.

If you don't check this you potentially will cause stress on the pump housing and adapters and cause a misalignment of the driven shaft. Not good!

Finally to get it to work properly I had to mill the notch in the spacer a little deeper so that it would sit flush with the main cap. I also had to machine a flat on the main nut washer to make it work out. The last thing I will mention is the hex key bolts that mount the billet adapter to the main cap. Make sure the bolts are flush with the adapter, or the oil pump will not seat properly. The machine work on those bolts left a little to be desired.

Tonight I finished installing the pistons and rods. So far, so good with the short block. I'll get back at it this weekend.

03-05-2011 08:16 PM 1930u- Assembling the 392
The pistons were all measured before the block was bored and at that time we also fit the rings and honed the pistons to accept the JE wrist pins. Everything has been bagged and tagged for awhile. All these parts are specific to the cylinder they were measured up for.

I chose Total Seal rings.

As today went on I did get 3 rod and piston assemblies installed. I'm a terribly slow engine builder because I treat everything like it's made of china. I hope to have the short block wrapped up tomorrow.

The wrist pins are almost 1" in diameter. Here's a couple shots of them and the buttons.
