5.3 V8 DI 400HP as the BASE V8

[2001Firehawk]

Got to thinking about Scott saying that we're in for some big surprises.

The biggest surprise I believe, will be what the BASE V8 will be.

From the get-go, I believed that the Camaro, was going to be the showcase vehicle, for the next generation of V8 engines.

The design goal will probaby be a BASE V8 with 100HP more, than the BASE V6.

With a 2.0L 260HP I4 , & a 3.6L 304HP V6 already done.
The time for the DI V8 is here now.

With everyone knowing that it won't be the LS2 , & thinking that it will be the LS3, I think that we'll be in for a nice surprise...

Nope.

The LNF 2.0L turbo DI engine was mentioned in passing by Bob Lutz as a possibility if CAFE causes a problem for the Camaro. It's not even remotely close to "already done".

The LS3 will be the "base" V8. The Gen V DI motors aren't quite yet ready to be released.

I don't know much about the 5.3 motor...what would its advantages be? Is it DOD capable? DI would provide better mileage - do you expect mileage figures to be better than with LS3?

Just curious and want to learn more

Unless GM is developing a new RWD 5.3L V8, the only 5.3L V8s in the lineup right now are the Vortec truck engines. They put out between 315-320 HP and 340 lb.ft. of torque.

He could be talking about the LS4, which I have in the Impala, but as far as I know, it's a FWD only engine. Besides, the DI 3.6 makes more power (though mine sounds better ), so why would you want an LS4? A 400hp 5.3 would be fun, but I suspect that's not what it's going to be.

Gen Vs will either debut in a Cadillac truck or the Corvette.

That would be cool.. probably won't happen out of the gate. But I'd have no problem driving a 400hp 5.3l Camaro if it got a few more mpg's...

When he said, "already done", I think he was referring to the motor being already done on other GM cars.

The LS4 is a FWD only engine. If it were put into a RWD application, the throttle body would be facing the firewall.

I know, that's why I said as far as I know, it was a FWD engine only.

It would be possible to put the LS4 into a RWD application if a new intake manifold were made.

However, I don't think there's any point to putting the LS4 into the Camaro.

you have zero credible sources.

The LS4 has the horsepower, but does it have the torque to move a Camaro?

You're looking at ~1000 pounds difference.

Which would be ideal for a functional cowl induction hood

323lb/ft for the LS4, 276lb/ft for the 3.6 DI V6.
