it's just a small 289, my uncle builds them to what ever the customer wants, he put a roush v8 in one and i believe a chevy 572 in another, he had a hell of a time getting them to stick to the ground

289,302,351,360,390,427,428,429,460
That covers it I think

yes, it's a ford engine

Thanks for the Rep
Sure hope there's a Ford Motor in your Cobra
