Absolutly this is a personal preference question. I have seen several of Keith Craft's 418 and 427 small blocks run on the chassis dyno and have ridded in a couple and all I can say is they are amazing. I chose to go the big block Genesis route. The hp numbers are very comparable who can tell the difference of 10-30 hp in a 600+ hp Cobra. The torque is where the biggest difference is seen the big block comes on earlier and stronger.

I just took mine for its first test drive yesterday and barely got on the throttle and it is nuts. I may have to change the rear end gears to make first and second more usable. I think for street driving the small block may be more managable as it brings the torque on in a more usable fashion. However being a power nut I am very pleased with the FE. eventually I will get on the chassis dyno at Keith Craft and get some rear wheel numbers but for right now I am targeting 500 for both hp an tq.

Either way these engines are nuts and require a lot of respect. Both are way more than needed on the street.
