I remember looking at used Kirkham with a 460 a long time ago. The owner had to significantly clearance the frame to fit the 460. So, I wouldn't ever want to do that to my Kirkham.

The 460 could be lighter, cheaper and make more HP, but it's clearly undesirable to the greater Cobra market and has been since the start of the Cobra replica in the 1980's.

The FE is superior in value and appearance. There's nothing like seeing an FE with a turkey pan in a Cobra. The Cobra is not the latest gotta-have-it iPhone. People purchase Cobras replicas to replicate the Cobra experience and FE's are the clear winner in terms of value to every Cobra owner who installs one. But not every Cobra owner values the FE and that's OK. That's why there are various Cobra manufacturers who install various drivetrains for various types of customers.

Personally, if cost/HP/weight/parts availability were more important to me, then the various LS alternatives from Chevy would be more appealing than a 460.
