hello i have just been offered to buy a 91 f350 locally that has had a complete drop in jasper engine just under 40k miles ago and it the reg cab 4x4 with the five speed. He doesnt have much receipts except for the motor some oil changes and various other things. Thats all fine and dandy except that when i asked him about what brand of coolant additive he has been using he didnt know what i was talking about. So if this whole time hes been using just like prestone 50/50 how much damage has he done to the engine from not using the DCA. Also should i buy it? im afraid that the thing is going to messed from not using the DCA even though he says it runs and starts perfect. One last question if he is pulling 2100 rpms at 60-65 mph does it have the 4.10 gears in the axle?
