I have a pair of nice 920s in the attic I think the chambers were 58CC but it has been a long time and going strictly by memory on that. Maybe I could find some cheap 1.6 or 1.7 shaft rockers and a long runner MPI intake for LA heads... better yet could I buy a TBI with 8 injectors and just extend the existing wires to pulse them? I really think TBI is the best for an MPG project, the last mass produced engine sold in the USA with TBI got 50+ MPG.
Those heads on a roller/magnum tweener 318 block with the kegger and your 92 obd1 might be an interesting combo. Might help you get another 1pt of compression you mentioned you wanted depending on how much the heads could be cut.
