Mustang Has a Motor!

I took the donor motor to a local engine builder and after a couple of weeks he had it ready.  The big day was scheduled for it to be run on a chassis dyno so that we could see the power output and be assured it was tuned and running well.  Brian came down for the occasion.  Here is the motor mounted in an old race car chassis and hooked up to a Dynojet dynamometer:

 

The builder started it up and ran it for awhile at moderate speeds to warm it up. It sounded great and ran super smooth. Then he started some max power runs:

 

He had it tuned to run with mufflers, which is the way we will have to run it on the street, but just for grins he removed the mufflers and ran it with just the exhaust headers.......we all had to wear hearing protection, but it sounded awesome!  There is nothing like an American push-rod V8 at full song.

Here are the stats of the dyno run taken without the mufflers.  The bottom graph shows it is running a little lean without the mufflers (the dotted red line is the optimum air/fuel ratio), but the rear-wheel horsepower is about the same......slightly over 200.  The builder said the horsepower at the crank, which is the way most engine horsepower is advertised, would be about 262.  Notice the nice flat torque curve also.  The engine is basically a stock blueprinted engine but makes some additional power with the addition on an Edelbrock intake manifold and carburetor, plus higher flow exhaust headers.  It should be able to run on mid-grade gas. 

 



 

We loaded it up in my truck and brought it home:

 

 

Then brought the hoist down, hauled it out of the truck and installed the  motor mounts, clutch and bell housing.  It sure is pretty, isn't it:

 

 

Before we could push the car over to the shed to receive the engine, we had to remove the hood.  I couldn't think of a safe place to store it but then Carolyn suggested we put it in the hallway.  What a wife, eh?

 So while Carolyn steered, Brian and I pushed the car over to the shed, then lowered the engine in and bolted up the motor mounts.  It's quick to write that process, but it took us several hours because all the holes in the motor mounts didn't quite line up:

 

 

 

 

After we got the motor in we pushed the car back to the shop and jacked it up for the transmission install.  This went smoother than I expected and somewhat made up for the difficulty in getting the engine in:

 

 

Still much to do, but these were big jobs, and from now on I should be able to work at my leisure.
