Looks like the LS7 will be replaced with this wet sump version that makes more HP & Torque.

I'm under the impression that's what was used in the newer Z28 Camaro.

Honest question here guys...for a street car with an owner that prioritizes torque but may not want the added packaging complication of an LSA, is that thing worth the $4,500 upgrade over the Ls3? I’m struggling with that decision...

I saw that, nice rebate for a T56 after buying the LT5 crate but right now, unless I can get a GM Performance Dealer interested in price matching, I can get T56 more than $250 lower from other vendors. I was going to get the cruise and connect to get the rebate but same thing, I can do better and pick the parts I want from other vendors.

I don't think there's any rebate for just buying the LT5 is there?

I had to go back and look. Appears I was looking at the connect and cruise, missing that detail. Sorry about that. But... I agree on sourcing exactly what you want from other vendors.

It's always a balance. There's a lot you can do to an LS3 to gain a bit more Tq. Talk to and engine builder or tuner and see what their thoughts are. Mike Norris Motorsports is who I'd suggest. They do a lot of upgrades and tuning. Mikes a good guy and has been at this a long time.

That’s a good call. Sorry for the hijack...that was a bad one :)

Connect and cruise never seems like the value play, always the convenience play for dummies like me.

It’s all good. Be watching to see what you end up doing.

:captain:

Just saw this myself.

Now I have to change plans as I see Summit has 6 of them and Jegs has 1.

Is the LT5 worth the few grand over the LT4?
Or should I go with the LT4 and upgraded it down the road?


This is going into a 55 chevy with a T56 in case anyone was wondering

Me personally i'd say it's worth it over a LT4. Blower alone makes that difference to me.
