Yes, they are carb motors.

Actually, Ford motorsports used to sell a box and coil swap for the DuraSpark. I used these in all my race cars. They were simple bolt/ plug ins being dimensionally the same to the Duraspark box.


They were made by MSD!

Now that they are no longer made, I will have to go with the regular MSD boxes, which will probably need to go inside the passenger foot well.

Why MSD?

They are readily available and do work. Do not think, however, that the DuraSpark is that inferior.

Cheers.
