I voted diesel. I think our 60's were meant to be diesel for long journeys (more range) and the unique factor is more suited for a 60.

I have driven the LS3 in a chev and it is smooth and nice. And would still be a so much better than a 2F or 3FE. Maybe a 1000x better.
 
Plan around 10 for connect and cruise, but then budget another couple for accessories, starter, ATF cooler lines, bolts, etc. The list goes on. The total parts cost down to every bolt, AC, crimp, drivelines, will be around 26k
 
Can the Cummins 2.8 run on straight bio diesel? I know our diesel work trucks have a B20 max and even that can cause issues. The Cummins 12V runs great on it... but it could run on just about anything.
 
Check out Chev’s Hi preformancy connect and Cruise site. Many crate engine configurations with trans.
 
LS3 if it's between those two, IMHO (Yes, I'm one of these types) a 2.8l 4 pot isn't enough engine for anything other than a 40 series, and even then... Power figures on paper are one thing, but in real life, there is not all that much that replaces displacement.

Comparison: Holden Colorado and Ford Ranger: (I don't know if you get these in the states) Colorado has a 2.8 4 cylinder TD, ranger has a 3.2 5 cylinder. Both make 147 kw and the ranger makes 470 nm, the Colorado 500. Empty, Colorado is slightly faster stock, but throw a trailer behind them with a bit of weight and the little 4 cylinder kinda falls a bit flat, same with most of the small displacement utes like Amarok, Navara etc. They're good on paper and as a driver, but make them work and the lack of low-end torque kills them.

Is something like a 12HT, 1HD-### a possibility?
 
Given that the 2F drives like a diesel already I'd say go diesel. But I also know that the install cost of the diesel is quite a bit higher....theoretically you could do he SBC swap for less than the purchase price of the new 2.8 engine.

Actually with the price of the way SBCs are now days and LS variants, you are basically paying close to the same for both. So if you are doing that then step up to the LS variant. Yes there is more computers and whatnot that need (or may need to be) connected but the trade-off from talking with guys that do this on a regular basis is night and day unless you are going for something very specific with the SBC. That or you already have one on hand that would thus save you the cost of having to purchase an engine.

If you are buying a new crate motor then I agree. But at least with a SBC you have the option of buying a used engine or a vehicle with the engine you desire. At this point I don't think there is a vehicle on the road with the cummins 2.8...unless thats the engine in the liberty diesel?

either way...coinage must be outlayed for both ;)

Same goes for the LS... can easily purchase a wrecked one with engine and everything.

Don't the new Canyons come with the 2.8 in them? That is the only one that I can think of offhand, think the Liberty came with the old 3.3BT.
 
If I were you I would do a Mosley Motors Hot Rod 2F or 2FE ( I am not sure the specifics)

Really it all comes down to what the final outcome plan for the vehicle is? I know a few guys that still rock their 2Fs in their 40s, crawling, armored, etc. and are just fine.

I think that the 2.8L diesel shows that the old thought process of "there's no replacement for displacement" is really not completely accurate. In an apples to apples comparison thing may be closer than you would anticipate. I think Tor (@torfab) has shown that with his 2.8 powered 62 and then you have guys like CATuned with their OM606 powered 62 that have no real issues. When you get into towing heavy stuff, then you may start seeing the need for the extra power.

I have always lived by....
HP = I wanna go FAST
Torque = I need to be able to move something heavy (this doesn't necessarily mean FAST though)

I believe that the Cummins 2.8 is made in China and has been used in many of the Asian markets. I have heard that quality has been an issue. Don't know if Cummins has sorted that out or not.

HP = (Torque x RPM)/5252
