That LS7 intake kills HP compared to the carb style intake.
GM says the motor loses like 40+ HP going with the LS7 stuff.

The carb style one comes with bungs for injectors. Thats what I'm going with.

order cary's intake, it is very compareable in price and you can have the dominator flange to run the 4500 series throttle body and fuel rails.. Just ordered one today from Virginia Speed.

I believe the intake port size are the same as the production heads. So the FAST should bolt right up. I'd like to go ITB's but they won't fit under the cowl of a TA .

Guys,

The intake ports on the new LSX 6 bolt heads are similar to LS7 ports. Nothing else will work-definitely not the cathedral port stuff. The LSX-R intake from FAST will work, but if hood clearance is NOT an issue, go with the carb style intake from GMPP or others designed for LS7 ports - they will still make more power than the under hood stuff.

I will be running a SS hood, so I will go with the FAST intake.

Didn't I read somewhere that a 58x reluctor wheel won't work with our f-body cars? Which is what this motor uses...?

You just have to use the Lingenfelter Converter box to switch the signal back to 24X

A pretty good price overall. But if your going to layout that kind of money. Check with LME or another company and see what they can do with that kind of money. Shopping around is a good thing before spending.

Received my LSX454 last weekend. After checking around, I decided to go with one of the dominator flange intakes from Cary at Performance Induction Specialties. Note the 8 bolt crank flange that requires a new flex plate.

That is a beautiful picture of the new LSX 454. What vehicle will that be going into?

I am sure with a simple cam swap it would really wake up. I like this crate motor because it comes with a 2yr warranty.

I plan on ordering mine this week now that the chassis is done.

In reading the info on that warranty, there's so many limitations, it's almost useless ? Like No Alterations...

Usual, like any production piece but at least there's some assurance if someone gets a lemon ?

They outta do this in Aluminum and stuff it in the Camaro ?

Looks damn nice !
