My first Cobra had an EF crate 302. No problems except with the Edelbrock carb. Not well suited to these cars.

After replacing it with a double pumper and recurving the advance somewhat, the engine really woke up.

Go with the 351 and you will not be disappointed. And it gives you room to grow (408) in case you want even more power after a while.

Check out Smeding, Roush, Keith Craft and FRP. They all give you a longer warranty in case you will have the engine sitting around for a few months before you get around to starting it. My EF engine came with only a three month guaranty, and that was gone before I ever turned the key!
