Well okay, hold onto your hats...here's a big one!
I've read a ba-zillion posts here on what the most powerful engine is, what is the biggest engine you can shoehorn into the frontend, so on and so on. But this question is a little more thought provoking (I think).
Of all the engine/transmission combination choices available, what in your opinion would be THE ULTIMATE/BE ALL-END ALL for: Compactness, weight, power/torque and fuel mileage? Think about all these parameters and some of you great thinkers share your logic and reasoning.
I'm actually thinking of...drumroll please....creating Frankenstein II! But this time I want to think outside the box just a little. Maybe fuel injection, maybe turbo diesel, definitely something getting better gas milage than 8.8mpg! Right now I'm running a SBC, 4bbl Holley 650,SM465,Np205 and stock axles.
Maybe a BIG 6 W/fuel injection...whatever....
