Darryl,
John is correct, the DMC heads WILL bolt to the Eagle block, as long as 
you use Eagle head gaskets. By using the D heads, John will also be able to 
use the entire K-Jet intake system from the D, which should make the hook up 
of the fuel system pretty straight forward. And since the K-Jet is a constant 
injection system, it should work equally well with either the even fire or 
odd fire setup. You are also correct that if he stays with the even fire 
crankshaft in the Eagle block, he needs to use the even fire cams and valve 
train also, which again will fit in the D heads. This will also require that 
he run the Eagle even fire ignition distributor off the front of the motor 
and plug the hole in the back of the D head for the D distributor, which 
should not be a problem. Matter of fact, having the distributor mounted on 
the front of the right head will make it much easier to work with, and it 
sounds like John's already got the fix for using the E ignition system with 
the Delorean electric's from some of his prior projects.
I don't know what he's going to do about the compression ratio of his new 
motor. The D heads have smaller chambers then the E heads. My calculations 
show a stock D head on a stock E block will produce a compression ratio of 
about 9.9 to 1, which isn't too bad. This increase in compression should bump 
the engine output about another 10 HP. Testing has shown the stock Delorean 
K-Jet fuel system has sufficient volume to handle up to about 200 HP, so all 
in all, I'd say John is working on one of the most "user friendly" PRV 
swaps/upgrades that can be done. I'm not trying to imply this is an "easy" 
project to do, but it is a combination that makes a lot of sense to me.
I think John has maybe come up with a very workable combination, and I 
congratulate him on it. Darryl, please keep us up to date as things progress.
