Hi all,
As you know, last year I purchased a 1976 Monaco Class C motorhome, built on a 1975 Dodge MB300. Although the 360 2bbl only had 58,000 miles, I wanted to pull the engine and freshen it up. Years ago I had a 1973 Fireball Class C built on a 1972 MB300 chassis, and the nylon timing gear gave up the ghost with little more than 52,000 miles, so I wanted to upgrade some of the components and have a reliable lump that would give us years of fun.
When I pulled the heads, my eye caught a visible casting flaw between the #5 & #7 cylinders, and I'm amazed that the head gasket never blew. At this point, I knew I was in for a rebuild. When I started doing my research, I found that buying a reman'd 360 would be cheaper than having mine machined. I bought a reman'd 360, bored .030" over, from a seller on eBay for $1595, no core charge, free shipping and a 5yr/unlimited mile warranty. The seller also let me pick my own camshaft, so I went with a Mopar Performance camshaft P4452759AE. My understanding is that this cam closely resembles the cam that was in the 340 and what Mopar used in the E58 360 police engine. I'm also swapping in a 4bbl intake and ThermoQuad carburetor. When I ran the numbers on the desktop dyno, it gives great torque through 3500RPM.
This last weekend I finally pulled the old block and dropped the A727 LoadFlite. Since I have a reman'd engine, I might as well have the tranny rebuilt, so that everything is new. I'm also going to install new motor mounts, trans mount and rubber suspension bushings while I'm in there.
Here are some pics of my work so far. If you guys have any suggestions, I'm all ears. It's been years, since I've tackled a job of this size.
