Sanity check re engine swap options/planning

Everything you are reading is pretty good info but the one thing not mentioned is the steering.
I installed a street semi in my 67 Barracuda S. Those cars had no power assist equipment which meant no power steering. The big blocks are substantially heavier than the "6". So what ever you do, retain the power steering system. My car is really tough to steer unless you are moving. Parking it is awful. I installed the Hemi in the late 90's and so it is now out of the car getting new rings, bearings, a head and valve job, gaskets, and seals etc. I keep looking at the empty engine compartment and the manual steering box wishing there was room to install a power steering system but there isn't. So I recommend you keep the steering system in mind when adding 300 pounds to the front of your car.
