10-14-2013 07:50 PM 1930u More tuning today
The old 392 Hemi is really coming around. I spent the day playing with the carbs and fixed a few small coolant leaks. The Edelbrock 750's currently have the stock set up inside but I changed to a lighter set of step up springs for the metering rods. This took care of a slight bit of blower surge at idle. she idles at 1000 RPM. The timing is set at 12 degrees initial with a total curve locked out at 32 degrees. All in by 1800 RPM. If I increase the boost later on I will probably have to take the total advance back to less than 30 degrees. The electric water pump and cooling fan are perfect. When the fan is on at idle she runs about 170 but I need to change the fan temp switch lowering the turn on to about 160.

Thanks to the junk SPEEDWAY MOTORS brand new leaky hydraulic throw out bearing I have to pull the trans and replace it with a Howe unit. If I get the seat belts and windshield installed by this weekend I plan to go down the road in this thing.

09-19-2013 08:57 PM 1930u Calibrating the carbs
Now that the Hemi is running I'm going to calibrate the carbs. Big Al at Big Al's, Toy Box gave me some tips on running the Edelbrocks on a 6-71. So before I go out on the road I'm changing to his specs. I love the Carter (Edelbrock carbs) and have used them on my 409 and many, many Corvettes over the years.

09-17-2013 09:51 PM 1930u- The Hemi fired right up
Last night after working through many issues and after 7 years of work I finally got to start the 392. All I can say is Wow! This thing is bad ***! I ran it about 20 minutes at 2000 RPM to break in the cam. I had couple of coolant leaks but the old motor is okay. The stainless headers changed to rose gold and are looking good. Can't wait to get it out on the road.

09-17-2013 09:22 PM 1930u throwout bearing problem
Per Speedway Motors warranty they would only send me a rebuild kit for their defective throwout bearing. Bottom line I rebuilt it and the darn piece of crap thing still leaks. Long story but I will have to pull the trans again.

09-17-2013 09:01 PM 1930u set back bad throwout bearing and missing oil plug
A little over a week and a half ago I was preparing to start the Hemi. When I crawled under the car to hook up my remote start button I saw a drop of fluid under the bell housing. Upon inspection I found the new $100 never been used Speedway Motors hydraulic throwout bearing was leaking. Why me I asked?

Not a pretty picture and to make matters worse when I tried to prime the oil system I had only 20 PSI on the gauge...only to discover the engine builder (me) forgot to install the left internal oil gallery plug. The machine shop had removed it to clean the block and me not being familiar with the old Hemi just missed it. The only way to install it is to remove the left rear external oil plug. Since the throwout bearing was leaking I had to remove the trans any way so it wasn't a big deal. Live and learn but I was really bummed out so I left it sit for a week.
