right now my 1995 chevy k1500 has the 305 in her, i dont mind but i just want more juice and better fuel economy than a big block, so i was thinking a cummins 12 valve swap. i know a little from what i read but what i really want to know is how the fuel works, like how do i convert my gas tank to diesel and are there going to be any other problems i would run into. i know the oil pan would have to be modified to fit on top the ifs, and an adapter for the tranny and all that i was just wondering if anyone knows a step by step plan for me to follow. any info would be awesome.

if your asking for 'directions' dont even do it, it's too complicated if you dont even know where to start. :dunno:

i know what im doing it just that i dont want to be out of a truck for a month. if i can avoid and problems before i start it would save me time and money.

if you cant have it down for a month id recommend not to even start it. takes most people several months with all the problems youll run into and a 6bt in a half ton = bad idea

If you but the 6bt in your obs you better be ready to change your transmission, transfercase, and both axles. That is a lot more torque than the ol 305.

Agreed. The first time you put the pedal down your gonna end up with a bent frame, a blown 10 bolt and your trans is gonna take a crap. Do a 4bt
