GM's 2.7 Liter I-4 Turbo L3B Engine
That is a massive 4-cylinder engine! Impressive torque though.
I can’t imagine the logistics of tuning it with that valvetrain design. So many variables!
Pretty cool though.

I’ve driven one for about 1k miles and will be driving it again next week. Haven’t towed anything with it but if I had the choice between the 2.7L and 5.3L I’d choose the 2.7L.
