There have been a handful of guys who have stuffed 6 cyl Cummins B engines in older 'Vettes. Whether they used dry sumps, I don't know. Bubble hoods are common among modified 'Vettes and are available off-the-shelf. The four may have some minor clearance issues by the problem is not insurmountable. The Cummins 6 cylinder weighs over a half ton and would make the car too nose heavy. The four weighs about asmuch as a 454 and there is no shortage of 454 'Vettes (C4 and older) running around.

Too bad the GM 4.5 liter diesel is as dead as OJ's acting career.

The bigger problem for me is headroom. "Vettes are designed for 6'1" max guys. I probably should start with a convertible and make a aero but taller coupe top.

Performance is something I don't sweat. The 4BT3.9 can be easily and safely turned up to over 250 HP. A more streetable approach is only turn it up to maybe 150 HP but double bottle (propane/nitrous) the engine for short bursts of fearsome acceleration. The 6b5.9 has been hot-roddedto over 900 HP, and 600 HP versions seem to be lasting, so a short burst (15 sec) double bottle 4BT3.9 should be A-OK at the 400 HP level.

Another option might be a M-B 617.952 engine, but those make very inadequate low end torque. The Cummins is a torque monster and not a bit put out about running at 1100 RPM.
