Helo Everyone-I am considering installing a 372 ci Perkins into my V2500 4x4 1991 Burb.Can anyone give me the pros/cons of doing this?I would like to keep my 4L80E tranny(do I need a special shifter unit?).The motor in there right now is a 350ci gas pig.The main reasons I want to do this is because the Perkins is sitting on the shop floor doing nothing and the few people I have asked about doing this tell me it is not possible.The adaptor plates I can fab up in the shop.Any comments would be appreciated.Thanks.
