Concept LT5 + Concept Northstar in Concept Banshee = W...T...F...?! Was perusing Google Images for stuff, and came across a picture of an engine that I figured had to be a concept of the LT5, until I actually went to the page to find out that it's not. It's a 4.0L DOHC like the LT5, looks to have the same intake as the LT5 (but with standard TB), yet it's a singular block with no actual heads o_0 How it's DOHC system works, I'd love to know, as I can't even begin to imagine. Such as, how the valves are put in, other than maybe with the engine completely apart and you have to weasel them in through the cylinders heh I wonder if the "engine program that was abandoned" was the one GM worked on for a DHOC motor based on the SBC, before they found out it just wouldn't work and commissioned Lotus to design one (which became the LT5). There is no basis for me using "Concept Northstar", it was just the really small 4.0L that made me think of a NS motor heh
SUCH an odd duck!

the 4th gen resemblance is close, and I really like the idea of an integral block/head design, eliminating heads is a great idea for reliability, and deffinetely for performance!!!
I would liek to see this style of engine completed in anything!

Lets port the heads! Oh, wait, cant cuz they are part of the block. Plus, performance was horrible - all the extra complications for only 230hp?

The 91-92 were also based off of that, but just the front bumper and spoiler. It was a bit of a sneak peak into the 4th gen body style for the Firebirds.
