No its not a turbo and I have yet to get a reply back from the gentleman. Hope I didnt sound sarcastic I simply welcome the challenge of the roadranger. Realy excited about moveing forward on this build. Found a 6v-53 and a web page that gives the dimensions of the engines and there weight.
4-53:39" long 27" wide 37" height 1110lbs
4-53T: 40" long 32" wide 37" hieght 1300lbs
6v-53T: 39" long 37" wide 41" height 1695lbs
6v-53: 39' long 40" wide 37" height 1485lbs
Think if I box the frame were the engine mouns I can support the extra 395 for the 4-53T?
