Thanks for the reply, but like I said, it's the old school thing....
Sure the electronic injection has its advantages, but I'm hesitant of converting over with all of the brains and wiring issues. If it really came down to doing the conversion to electronic fuel injection, I may as well just transplant a 32V motor into my 928. (I suspect it would be very expensive and beyond my technical abilities.)
That being said, it would seem to me that 400hp is easily attainable when you're starting out with (comparatively) a small block that already does 229hp (my Euro 4.5 16V), before a short block change.
Heck, a 5.0 Mustang does those kind of numbers without even breathing hard.
As you have pointed out, though, the real meat is in the heads and cams, and the K-JET can be made to handle upwards of 500+ without too much fuss...
Keep after it, and I'll keep watching.
