Correct carburetor for the `71 429 SCJ Mustang.

Note that this carb has a dashpot which was used on a 4-speed carb. A C6 Holley would have a solenoid instead.

This photo shows the correct belt routing, bracketry, and accessory drive (not including smog pump) for the 429 SCJ.

Here is the best horsepower / torque curve of 6 dyno runs made on my engine. The engine is a production rebuild. Stock, except for .030" over, roller rockers, and Petronix Ignitor. Optimum power was achieved at 39 degrees of total advance.

This photo shows the engine during dyno testing at Total Engineering.

This photo shows the completed and tuned engine after returning home from the dyno test. Prior to the test, the distributor and carburetor were installed and the solid valve train was adjusted for the first time. The engine's intial breakin then took place on the dyno, after which fine tuning of the timing and carburetor took place over 6 runs. This whole process took 9 hours.

Here I am with the completed engine assembly (with C6 trans attached) ready for installation.

Removal of the 351 Cleveland to make way for the 429 SCJ.

Shot of engine compartment without 351. A lot of cleaning, repair, and repainting is required before the 429 can go in.

Here is the primed engine compartment, finally ready for paint after 3 weeks of work!

Finally, time to install the engine and transmission.

Another shot of the installation. It took about 45 minutes of carefully lowering the engine, changing the angle, and rolling the car body forward to get it in.
