Champion Radiator w/ LS info needed

[Root2812]

Hey guys. So my cab if not on the frame and I want to position the motor in the frame on my 1950 chevy. I decided to position it close to the radiator to make sure I have clearance to the firewall rather than place it off the firewall to have clearance up front. I think it will work out the same either way and I got adjustable mounts from dirty dingo incase I need to fine tune it later. I am going to avoid modifying the firewall.

I know champion radiators are spoken highly of on the forum so I am going to get one. For those of you running one with a 5.3 did you go with the 3 or 4 row radiator?

Anyone running a champion, What is the total depth front to back with the electric fan attached? What fan? I think champion sells one with the radiator so I may go that way.

Lastly, If any of you are running a 5.3 (truck accessories) with the champion set up please share some details and some measurements of the front of the accessories to the back of the fan.

With your guys' help I think I should be able to get my motor in using just the radiator support I have laying around and making a cardboard mock up radiator and fan with your dimensions. I have some replacement floor pans with the toe board to lay on the frame too but no firewall.

Thanks in advance for the posts.
