xb-60 No Glen you asked question and guys have tryed to give the best info they have. I will be unreal to think you can build a motor with the specs you want. The cost on this motor will be large also. I did have an idea about this, Fine a set of gurney westlake heads and intake, this will get you into the ball park. As other have said, running an FI system might have to be also done. Rick L. Ps you can start this trip by looking and buying a "k" block. Nothing more than .030" over bore and the correct main caps to THAT block. Need soda and popcorn,
going to work.
