My Super Nova 19
MOTOR BUILD

360ci/330hp
____________________________________________________________________

This is the sixth and final version build sheet for the first motor I installed in the boat.
The Chrysler LA360ci.
If a part could be bought for it, it was and they all cost big time.
I have a long and sorted history with this motor for the few years I had it in the boat that can be found in the section. Many rebuilds and changes due to newer things or money coming available, let alone fixing the screw ups I made.

What a great motor. Good things do come in small packages.

It has been a very long road to get to where I am at now. The first Chrysler small block I ever worked on was the motor for this boat. About every year after I have had the motor out for upgrades. I will spare you "all" the details of things that didn't work out the way they should have. Like when I installed a defective set of roller rocker. That cost me three top end rebuilds with cylinder head work each time. But now the top end is the best possible from improving on what I learned each time I did it.

Lets get to the good stuff.
It was a long road to the top picture starting from the picture below.
Only a few irreplaceable things are left over from the old motor but not much.
A very tired 318ci.

The first thing I did was strip off all the parts that were needed, then sent the rest of the old 318ci to the scrap mill.
I then went to the local junk yard and found a Chrysler 360ci motor out of a Dodge 15 passenger van and striped it down to the block and sent it off to the machine shop. Before the cylinders were honed I went to my favorite parts suppler, Northern Auto Parts to get a "Master rebuild kit" so the machinist could measure the piston heads to make sure they fit the cylinders perfect. From there the build was on. Like I said before I have done it again and again just because I found I could have done things better then I did the time before. The final results as of Spring of 2005 are as follows.

Dyno test sheet on the motor. The numbers don't lie.
 
  
I had to copy the cooling system from a motor I found in a old boatyard.

There is also a lot of little stuff, but nothing worth mentioning as a standout. I have found a lot of little things do add up though. Also a little TLC what you do install dose go a long way.
I know some will say, "that wont work". Something that always comes up is the carburetor. "A 750cfm on a small block is to much!" Again I say to that, I have done it over and over. I have used a 600, 650, 750 and 850 (most were new or close to it) and I got the best performance out of the 750cfm.
I also can not say enough about having everything that moves inside the motor balanced. I will never build another motor unless I have it done before assembly.

Just back from the machine shop.              Bottom end together.
Lots of motor, no electric.        Ready to go. For the first time.
The forth, fifth or sixth version.
I forget now that I have done it so many times.
