6.2 diesel

[Beefcake]

Got one of these in my 84 burb.

Im new to diesels, so bare with me. I want to do a complete rebuild, I've noticed the the 6.2 seems to have bottom end problems. I bought one with a shattered crank- for parts, only to find that this is common. I wonder if I should go with a steel crank then? Also, how far can I bore this sucker??... Does a larger cam help performance- Like a spark igniter?? And what kind of compression is optimal?? (everyone tells me that the more compression- the better) Then why not have dome pistons???

Also, How compatable are the heads from the 6.5L??? And, if I can just plop on the heads, can I also just grab a turbo 6.5L intake while Im at it???

thanks!!
