I've never cared for the modular engines. Those are very costly to build and dont seem to hold up very well.
i will say the coyote engine is impressive just not enough to make me a mod motor guy ?
you can make the little fords run as good or better for about the same price as a sbc ?
However the ls motors are the way to go at this time as far as bang for buck. Im actually about to build a ls powered fox mustang ?
