I currently have a 95 SUBURBAN with a 6.5. It's got 3 freeze plugs leaking, and a blown head gasket. I started looking into it further and have found that I have block rot goin on. This started within 2 months of me purchasing the truck. SO I've been crunchin numbers, and a CUMMINS conversion looks alot better than spending the money on a longblock. And if I'm going to do a conversion, I'd like to make it unique. The old saying "WHY BE NORMAL" fit's me to a T. With my current set-up, I'm running almost 2500 RPM's @ 70. SO the stock 12V red-line of 2500 won't give me much top end, and I don't want to ditch my 4.10's for towing. I'm not really up on the performance end of the 12V engines, but had always heard that had a fairly narrow power band.
I worked on them in stock form for DODGE, but never dabbled much with modded engines. I didn't know if a gov spring would be enough to broaden the power band. I figured the cylinder head design would be a limiting factor. And with my zest for being unique, I figure why not a completely custom CUMMINS for my swap. And with all of the VP44's I changed for DODGE, I want no part of one of them. The common rail engines seem nice, but you just can't beat a P7100 for reliability. I know it's alot of work, but I've seen some high milage 12V's lately for under $750 that need freshening. SO I figured pick one up complete, then freshen it up with 24V pistons. Swap in a 24V head and the rest of it to make it work. This would give me the cover, gear's, and other such conversion items straight from the get go.
My other viable option is to patch up my 6.5 good enough to sell it, because I'll never get my money back if I put a new 6.5 in it and sell it. And go out and buy an EXCURSION diesel. I don't have to have the SUV, but the room sure comes in handy. And I rarely need a pick-up anymore.
