Wow I need a 390 to replace my 360 with. Wish I lived closer I'd buy one of those in a heartbeat. Congrats on your new engine. John

I got the old motor pulled out of the truck today before it stated to rain. Went to work Sunday night and didn't get home until 6:30 this morning, so after large large amounts of coffee, I got started on the truck. It came out smooth and easy, no problems. I'm sure glad I pulled the front clip this time, only had to come up about a foot or so instead of 4 or 5 feet to clear everything on the high boy! The clutch and pressure plate looked good so I'll rerun those. In the morning I'll run to the parts store and get a new throw out bearing and pilot bushing just to keep from having to wonder about those. Hope it doesn't rain tomorrow! :pray:

I got the motor in yesterday. It took all day and had to call in reinforcements but we finally got it. I couldn't get the clutch lined up, used an alignment tool and tried everything I could think of but just wouldn't go. Finally an uncle of mine stopped by and suggested we pull the towers for the motor mounts to get a straighter angle and it slid in like butter. (wish he would've showed up 3 or 4 hours earlier!) I forgot to take pictures but I'll try to get some before I put the front clip back on in a day or so.

It's not a "new" motor, but a rebuild, but even a rebuilt long block for $400.00 is O.K. with me!
That's great!! I hope it runs like a million bucks for you. :thup: :thup:

Today I finished hooking up the motor and put the front clip back on. Everything went pretty smooth. When I tried to start it I had no spark at the coil wire, so then I rechecked the point gap. It was good but still no spark at the points when I turned it over. But when I touched the points with the screw driver there was a spark. Then I turned It over with the starter and still no spark, but every time I touch the points with a screw driver there is a spark from the screw driver to the points. Now I'm really confused. Any one ever heard of this? It doesn't make any sense to me but electricity isn't my strong point.

pull the cap off and with the key on, spin the engine over with the end of the coil wire from the cap-side, about a 1/4 inch from the top of the rotor. If it sparks, bad rotor.

I got the engine started up today! :D After talking to a couple of old mechanic buddies last night, I went out and bought new points, condenser, rotor, and coil. Installed them and she fired right up. I don't know where the spark problem was, but the new parts fixed it. I let it run for 15 or 20 mins and come up to temperature, made sure it didn't over heat and had no leaks, then changed the oil and filter. After that I went for a little spin that turned into a 60 mile drive, making sure not to let it lug down or over rev. It ran good, had 60 to 80 lbs of oil pressure, and plenty of power. It sure feels different with a 2 barrel instead of a 4, but seemed to get alot better mileage than the old motor. I still need to set the timing and idle later, (I just had both set by ear), but it seemed fairly close. Now for a shower and a couple of "cool ones"!

Just alittle update on the new engine. I got about 250 or 275 miles on it, so far no major problems. I rebuilt the 2 barrel carb this morning. I had put a kit in it when I originally bought the truck a few years ago, but it had sat in the shed for a couple of years. I thought it would be OK but it was really cruddy inside and wasn't idling right. Now it idles smooth and accelerates faster. Must be time for alittle road trip! :D
