    Not sure if it counts since it is still a concept, but the XV-16 13.6L Northstar would be the biggest made. Production-wise there is only one size, the 4.6L.

    The XV-16 was in the Sixteen concept. The XV-12 was in the Cien concept.

    The XV16 engine built for the Sixteen concept car is a 13.6 liter pushrod engine. Supposed to make 1,000 HP and 1,000 lbs-ft torque.

    The XV12 built for the Cien concept car is a 7.5 liter, 750 HP, 450 lbs-ft torque DOHC (Northstar?) engine.

    Re: northstar question

    I was wondering if Caddy made a V-16 Northstar 'cause I knew the one in the SIXTEEN was a pushrod engine. The V-12 in the Cien is a Northstar. They had an engine sitting next to the Cien when they had it at a show and it had overhead cams.

    I remember someone at Caddy saying they went with pushrods for the V-16 to keep it compact.
