And this will prob be moved, but I found this infinitely interesting!

So there is a LS based 7.0 liter DOHC motor that is being produced by none only, Mercury Marine.. 750hp with a 8k redline.

Wondering how long it will be until they make one out of an LT based short block

Ah...when hell freezes over is my guess. They offer the LS of various flavors, using the GM short block and bolt on DOHC heads NOW. What would the incentive be to retro to the old LT block that is no longer in production??

Just my 2cents

I'd rather have the 9.0l. Having been around a few race boats, the 9.0l is one crazy sounding s.o.b.

That is cool I have heard of that engine before. Always wondered why GM ditched the overhead cam engines in the Corvette, but still used them in the cadillacs (northstar). That is one awesome engine!

The video was a disappointment. It is great to show engineers torquing and guys loading the engine in a wooden crate but was what missing was showing the engine in action. The burn out by the charger was cool but way too short.

I agree the 2nd coming of the lt1 would be a waste since it is an old design and similar to the first gen small block. I was curious about the most recent generation of the lt engines in the c7 corvettes. It is an interesting thought making one dohc.

Nelson Racing Engines does a 500ci LT5 out of billet head to toe. Aint cheap-
not sure if they still make them, cant imagine too many buyers for them with the pockets for it?

Bet that MM runs pretty well. GM cut the LT5 due to cost and they couldnt do one themselves that held together.

If I were a betting man, merc did a lot of work to that ls7 to bring it up to their standards... there was a reason why they built the lt5s in the first place. Then gm built some northstar heap and that got them real far.
