1955 Chevy 3600 Replacing 292 with 383

[Jonathans55]

It is time that i replace the current engine in my 1955 Chevy 3600. When i bought her she was a complete Frankenstein pieced together with hundreds of different parts. The 235 was replaced with a 292. The motor mounts have gone to hell. The engine is still strong but if I am going to replace the motor mounts id rather do it because i am putting a meaty engine in her. I decided on either a 350 or 383. When doing the engine swap my biggest concern is new mounts. Do they make kits or will i have to bring out a welder to make them? Also does anyone have a referral for custom radiators? I am going to have to replace the one that is in there due to the motor mounts being so ragged the engine was allowed to push the fan into the radiator. I want a cross flow and something easy to mount an electric fan to. I am an amateur when it comes to restorations and it is my first project. Any advice will help. Thank you
