I have a comment on all of this from my own perspective. Have been rebuilding an RF 2000, good car, the right parts, all the potential. During this process I have considered the MC deal and the ZETEC. To make this comment limited I will say that the MC deal, in my opinion, is for the pioneers and home builders at this point. Don't get me wrong it will be big someday and I am all for the progress. My problem with the ZETEC is what approaches $20,000 (I am not here to argue cost, once again my opinion) for the conversion of a good, late model VD done professionally. Even with significant reduced maintenance it will take years to recover the 20. I personally do not want to invest another 20K +/- in a FC where rules are presently generally undefined and the present performance level difference is very limited to undefined and then only by the best drivers and teams. SO, the Pinto, even though a more expensive engine to maintain (that is no brainer), is where I want to be at this time and let evolution go on at whatever pace it tends to go. My point mainly being that others that will race and support this class (reg./natl.) are made up basically of Pinto guys that may not have an additional 20K to keep up and/or want to spend it on an engine update. If the Pinto, at this point in time is not kept generally competitive by the powers that be, those same powers will systematically eliminate the very core of this class, not due to maintenance cost, but due to those presently involved not having or wanting to spend the $ for the other engine and the conversion BS involved.
