My requirements... what to build?

360 magnum
find trans core mentioned or an a999 transgo reprogramming kit u will need a b&m flex plate
ur in MI so winter driving?
you can drill your axles for small bolt pattern if 8 1/4 - right forum?
if the magnum heads are not cracked run them
figure compression b 4 thinking cam
heads you want almost 0 deck with .028 gasket like-7 gives .035 quench
or 0 deck with .040 gasket
cc your heads ( magnum) and compute cr before buying pistons and vice versa
vice versa is you pick your pistons and heads (and gasket) as a team
pick the combo that gives you he most dynamic comprssion for your fuel
figure your cruz rpm , the rev range you want and aj can run the numbers for you
figure your exhaust
stock efi ( not 95and earlier) cam would work you will need timing chain set
if you want more up top how much do you want to give up starting from a stop sign at part throttle
a lot of take out engines sold with compression check can be run otb
if you are going to do pistons and rebuild rods you might as well stroke it
cheapest torque / $$$
