LT2 Corvette Engine
I realize the new LT2 engine was introduced in the new 2020 C8. Is this engine being used in any other GM models? The reason I ask I just watched Jay Leno’s garage review and test drive of the 2023 Z06, he mentioned to the GM engineer that this Z06 was special because the all New LT6 will only be used in the C8 Z06 exclusively like no other Corvette and the engineer did not correct him. The engineer did mention Originally the C6 Z06 came out with the LS7 exclusively until they used it in the CAMARO Z28 and the 427 Corvette in 2013.
I would appreciate your thoughts and knowledge on this subject.

Corvette engines are usually shared with Camaros

Derivatives of them are usually used in trucks.

The LT2 was designed to be mounted low in the vehicle which could be accomplished because of the design of the transaxle with the input shaft on the bottom. I suspect other vehicles will have another LT variant for their applications unless they develop a bottom input shaft transmission for those vehicles.
I'm not saying it can't be done, it just would be sort of a waste to put a LT2 in a vehicle that didn't take advantage of the low mounting.

The shallow oil pan allows for adequate ground clearance when the LT2 is mated with the DCT transaxle.

My LS1 had a flat oil pan that wasn’t in the Firebird/Camaro. It’s not really a new trick to LT2’s and it’s still a modular design that can be applied to any RWD vehicle in GM’s lineup.

Not quite. The LT5 on the 1990-1995 ZR1’s were DOHC.
It was a purpose built engine just for the Corvette, designed by Lotus and built by Mercury Marine. Coincidently it also doubled the price of the Corvette. Purpose built drivetrains are not cheap.

GM said the biggest advantage to the LT2, in terms of extra power, was the ability to have the top exit, free flowing exhaust, a taller intake manifold since the driver didn't have to see over it, and a freer flowing cold air intake that didn't have to route over or around the hot radiator. To put the engine in the front of another car, you'd have to make the intake lower / smaller, route the exhaust around the transmission, and have a more complex cold air intake (like the C7's with 2 right-angle bends). GM also said the camshaft timing on the LT2 was revised to take advantage of the better air flow, so they'd have to change that, too.
By the time they were done, they'd essentially be back to the LT1.

The LT5 had DOHC but was still an OHV engine.

PS: See I responded with LT6 not LT2.
However similar high intake straight air shot intake into combustion chamber as a key to more power! He's pic. Would still stick out of a FE engine hood!

close but not exactly ohv means the valves are in the head not in the block like a flat head motor.

My first car was a 1941 Ford Business coupe; some called Opera Coupes as it had fold-down jumper seats in the rear leaving a lot of room for samples etc! It came with an economical small flathead called the V8 60 for 60 hp. It only had 136 cid. When I bought it over a year before I had my driver's license it had a 255 cid Merc flathead rated at 125 hp. I added the popular three Stromberg '97 cars and what was called "ported and releaved" the block. Doubt I got a lot more power. In any case was no match for the OHV engines in 1959 so built and early Olds engine all from parts I bought in peach baskets and had it bored 1/8 inches for '55 Olds pistons! A lot more power! Yep flatheads came in all sizes.
In fact Zora Arkus-Duntov when he first came to the US manufactured aftermarket OHV hemi heads they sold for the flathead! They were called "Ardun' heads for ARkos DUNtov!
