Back in college I had an XK-150 LeMans Coupe. Very few were made and a very, very few made it to this side of the Pond. They were built for factory sponsored or assisted race teams.
We literally worked on it all week to drive it on the weekends; but then, you don't expect a car that is basically a barely street legal race car to be reliable.
I've had the pleasure of driving both a C Type and a D Type Jaguar, and as you know, these are both pure race cars. Mike Hawthorne won LeMans in a C, or was it in a D?
As for putting a Chevy engine in any Jaguar - pure blasphemy.
Thank you, Jerry, for "seeing the light"

To swap engines in a jaguar and drop a Chevy V8 in one is like defacing a famous painting with McDonald's in the background.
Can anyone imagine Whistler's Mother with an iPOD and earphones?

Jaguars only had one problem (I know, I had one)

They ware fed through SU carburators, which were difficult to tune up properly, and had Lucas electrical system (LUCAS, the Prince of Darkness)
Had they had Weber or Dell'Orto carbs (both Italian, despite the name) and Marelli electrics, they would have been reliable as a farm tractor... start up first time, every time.
