I have a 944 kit from BCM with 11.5:1 pistons. Runs like a top and is a fuelie motor with the same heads and valves as the late carbies, with the exception that I have short manifolds, and herein lies the difference. I also had BCM do some head work and am pleased with the results. If I were to do it all over again I would do it again. The motor is reliable, powerful where I want it to be and was cheap enough to do (I did the labor). Bruce will tell you stories about 944 motors going long, and there is no reason they shouldn't.
