John Lane at Pacific Rim thought they would, so we'll have to wait and see how he accomplishes that. I do know he said he would be using the even fire cams and alloy rockers in the DMC heads. I'll keep everyone posted. >> 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. Marty
