Magnum block into Duster

No brainer! Just swapped in a rebuilt 5.9 into my Duster, all the accessories from an LA swap over, get either a Magnum intake or drill the heads for LA intake, or new Iron Rams which is what I did from Hughes so I could re-use my Eddy Air Gap. Just make sure you use a neutral balanced convertor and correct weighted flex plate, that's the only tricker part. Even LA valve covers will bolt up. Love the Magnums, roller cams, better heads all good stuff! Mines a stock stroke about 9.2-1 compression with thinner head gasket from scramspeed and a Hughes cam and it rips!

Did you use an old torqueflite or did you use the trans that came with the 5.9? I read somewhere you had to make additional fab changes to fit the trans in a duster.
