I have this 350 stock engine available to me for nothing. The 283 engine I pulled out is going to take a lot of work, complete rebuild. So how many problems am I going to run into changing the truck over to the 350? Seeing as it would still not be a stock setup I may opt to go with a newer automatic behind It. I know the motor and trany mounts would have to be changed. Or should I just wait to see if a 265 pops up somewhere for a reasonable price? This is for my 1955 3200 series 2.
