Engine choice

I think I will just go with the 318, it was running good last summer, actually for the last 5 years in my old truck.
I just pulled it to put a 360 in its place, I know what it is, simple ring and bearing, maybe a .010" cut on the crank, put some valve seals and lap the valves and run it. Also I have two more 318's if I need any unforeseen part.

Trans not 100% sure yet, but the 4-speed is tempting since I would use it also at a later date, if my engine block I have on order ever comes in.
