Chevrolet Performance - New LS7...

Chevrolet Performance is offering a new version of the LS7 - it is the LS7/570. Horsepower jumps from 505 to 570, and the torque jumps from 470 to 540. Scoggin-Dickey has it prices just over $12,000. It would make for a pretty good street engine.

Hopefully, they corrected the valve-dropping issue the LS7's are saddled with and went away from the titanium rods.

Re: Chevrolet Performance - New LS7...

Agree.....so many have troubles with the titanium rods/heads unless they changed that couldnt give me one
Hear the crate LS3s are saddled with issues too hope its just internet myth. Their 525 crate is a lot of engine for the money plus they are so durable makes you think..Rather have a vortecpro big block

Re: Chevrolet Performance - New LS7...

I don't consider my self to be some one who is stuck in doing things old school. I see these new engines and do think they are cool. But are they all that much greater? Durability? I have an 88 K5 Blazer that has 234K miles on the SBC and it still runs good. I have been banging around on the pretty much pieced together solid roller 454 in Old Blue now for 20 years/20k miles. Takes a few pumps to start after sitting but never gets much more than an oil change once a year and puts a big smile on my face every time I lay hard into the throttle. Heck with the girdle I haven't had to adjust valves in 10 years. I guess my point is hey they're cool but my old stuff is just great .

FYI got a new Camaro in the stable. 1970 RS Pro street that has an alleged 600hp t-ram SBC. Haven't seen it yet in person, on deployment for 2 more weeks. Kinda old school

Re: Chevrolet Performance - New LS7...

Yeah eff that LS, Jeff's new RIDE ROCKS IT OUT!!!!!


The new LS config is cool, and +70 ft lbs beats +70 hp! I was of the opinion that the typical swapped 5.3 LS dont generate good grunt unless boosted. I like grunt. Mid range grunt is best. LS7 seems to be there!

They've got to keep it warranty friendly, and mild enough to behave on the street... but MAST Motorsports is putting out 685hp from their crate LS7

I heard GM had issues with the sleeves on these engines but I've heard nothing about the rods.


I always thought the titanium rods were a plus, what problems are with them?

They have some kind of special coating on them, Paul, and it's starting to come off. When that happens, problems occur.
Many LS7's also had incorrectly machined cylinder heads, that causes high valve guide wear and dropped valves.

I see, thanks.

I would assume after all this time, GM knows about these problems and it's been fixed.

This is probably a good deal for somebody looking for a decent engine-with a warranty.

I think I could build a more powerful engine with a few better goodies, including better rockers and all ARP studs.
