I have a 1974 f250 trailer special with a 460 and a C6. Im currently rebuilding the motor it i have Edelbrock performer rpm heads (pn 60669), perfomer 460 intake, icon forged .040 over pistons, eagle H beam rods, comp cams adjustable timing set, comp cams die cast aluminum rockers, comp cams hydraulic lifters, comp cams cam, ARP main,rod, and head bolts, ATI harmonic balancer, comp cams push rods, and a couple other things looking at makeing around 550hp. Ill be getting a 2400 stall converter. I cant currently look at my axel to see the serial number to see what gears i have. I would like to see if anyone would know what could be in it stock. I would like 3.73:1 gears in it. Thanks in advance.

 

AXLE code stamped on the 2nd line-far right of the Warranty Plate, located on the left door face below the latch.

F250's came with the Dana 60 rear axle, Trailer Special ratios could be 3.73 or 4.10. 3.54 also available, but not usually seen with Trailer Special's.

 

Ok thanks for the input ill check my serial plate

 

'Could also decode the axle stampings and Bill of Material (BOM) number: Mr.N's Dana Articles to Include 44, 60 informaiton.
