Even a titanium slant six wouldn't fit in that engine compartment! It needs an engine with the pistons moving vertically. Perpendicular to the earth.

Plus the long stroke makes a very thrashy sounding engine. The AMC motor has it beat every way, including having enough main bearings, as in seven, rather than four.

The Ford 300 is even better, but it's the bigblock of sixes. The Chevy 4.2 DOHC inline 6 could be a very nice piece but it seems to have slowly died. Same displacement and layout as the classic Jaguar 6, I had high hopes for the motor.

The Slant6 lasted so long because it couldn't make enough power to hurt itself. Sorry, but true.
