Al,

Welcome to the forum. It looks like you have done some homework and narrowed your decision down to two great options--CSX 4000 and Kirkham.

I would suggest you give Keith Craft and Roush a call and talk with them about what you have in mind. Then you can make a determination on how well each might be able to meet your specific needs.

I suspect Keith Craft is going to have more flexibility in terms of the type of FE engine he will build (e.g., heads, compression, cam). I believe Roush only offers a few different FE configurations/options at this time (all based on the Shelby block). My understanding is that Keith Craft has built some more mild FEs for customers.

I have a CSX car with the 3.54 rear end and TKO-600 (w/.82 overdrive), and it is very good on the street. Incidentally, with the CSX car (and probably for the Kirkham, for that matter) it will be key to get the suspension and alignment "dialed in" by somebody who knows what they are doing (this will make a world of difference in how the car rides and handles). A lot of people have had good luck with Tom's Motorsports in Vegas for this.

Good luck.
