I am in the process of swapping out my three on tree for C6,I have a radiator our of a 77 F-250 that had a 400m and C6,will this radiator bolt right in and does it have the cooling capibility to keep my 385 series cool with a 19" flex fan thanks guys Chad
Chad, It should work, but I recommend that you take it to a radiator shop and have it checked for leaks, and if it is sound have them boil it out, or better yet spend about $180.00 or so bucks on a new one.
Chad, what fan are you using? When I did this swap, I used an '86 460, and everything bolted up fine into the truck, but I had to do some mixing and matching.
The '80s fan was too large in diameter, it wouldn't go under the upper radiator hose.
I am using my '66 (designed; a brand new one) 4 core radiator, a 7-blade fan from a '77 F-150 that had a 400 motor, and the '80s fan clutch.
The '86 water pump has a larger shaft.
The '86 fan clutch fits the larger shaft, but the '70s fan clutch will not. The '70s 460 water pump has a smaller shaft.
The 70's fan blade fits the 80's fan clutch.
With a 190 thermostat, I don't get above the middle of Normal at 70 MPH running empty.
It doesn't get out of normal at idle, either.

Griffin makes an aluminum radiator. very expensive and made to order.
The boat anchor radiator you have may not have the inlets and outlets correctly placed. Best bet is to order a four core modine for the 385 series and be safe.
