Possible 360 build...and other questions

Finally got a set of later model 318 heads that were not cracked. Hope to have the motor back together by the first of the year. Then the car will go back to the bodyshop for final paint!!!! Hopefully it will be done and on the road by March. That would give me the summer to enjoy it, AND plan my next project buildup. Either the above mentioned 360 build for my 70 Duster or a similar built 440!!
