I would still say that Hp/$ the 385 series stroked is hard to beat. In fact a good set of heads, cam, and intake on standard 460 will make all the Hp and Torque the average guy can handle, for a very reasonable cost. The only problem is it takes a big shoe horn to slide one in.

Windsor stroker costs more, but fits a lot easier.

I have no idea if this new engine can be stuffed in, but the price tag is attractive enough to give it some thought.

If I was going to go for maximum performance in terms of weight and handling, I would go aftermarket 5.0 Windsor block with twin turbo set up. However I don't think any of these belongs in 427 Cobra, but they would all run well, and that's up to the owner to decide what they want.
