The Crooks were nice enough to include some suggestions:
automatic transmission version of the engine WITH the fly wheel and COUNTERWEIGHTS. Also get the oil coolers, try to get a starter from a MANUAL transmission car; all fuel system parts EXCEPT fuel pump; you can get the Mazda coils if you want (they are heavier than after market AC delco coils but they will work fine); intake manifold (you can cut it apart and make your own manifold from it). We do not use the Mazda radiators for anything (too large for our use) but if you need them , get them of course. We also do not recommend turbo charging the engine but, again, that is a personal choice.
Would anyone recommend additions or correction for the Cozy IV?
