Re: What engine should i put in my 82 crew?

the new trucks are so over priced its not funny. but i know that some of the guys on 4btswaps.com are getting 25+ mpg with a cummins and same with the detroits. its all in the gearing. i am finding that alot of the diesel trucks are geared wrong for where we drive them now. they are to low in the rpm band to make good power so they use more fuel or they are geard to low and are to high. meaning that at 75 instead of will say1800 rpm its at 2200 and vis versa for the low side
