Lots of questions!

Don't make the mistake a lot of Cobra builders have made by thinking that the 400 to 500 hp 427s are not streetable. They are quite streetable. No they don't lurch in traffic unless you want them to. I have spoken with many guys who after completing their builds and driving for a few months, with they had went with more hp. With all the low-end torque these motors have they are generally very streetable.

I would suggest you find a few locals or somewhat nearby guys that might take you for a test drive, or at least let you ride in their car to get an idea of what they are actually like before you decide.

Maybe go to one of the larger Cobra shows or track events and drive a dealer demo with a 400 to 500 hp engine. My '66 427 sideoiler is a little under 600 at the flywheel and it is very streetable. Of course, I like the shake and roll from the rough idle at the stop lights. You just have to be more careful when and if you nail it. Be sure there is lots of room to the front and on both sides of you. It is amazing how quickly we humans get used to things that were at first scary and threatening.

Sounds like you are gonna have a great car with either the CSK or Kirkhan. I wish I could afford one or the other...but alas. Take care and good luck. Bob
