GM Performance Parts LSX Bow Tie block.
The 454 LSX Engine Cranks Out Over 640 hp and 610 lb-ft



In its final form, the LSX offers the potential for a massive 4.25-inch max bore that allows for 482ci from a small-block LSX engine using the max stroke. And, with the forthcoming tall-deck version (9.7-inch deck height), you are looking at 510ci small-blocks.

For the icing on the cake, the LS7 heads are a major upgrade from
previous versions.

The ones used on the engine in the photo above where a prototype LS7 head flowing 360 cfm @ .700 but no info on cc.
The cam was only a 236In.& 246Ex. @ .050 with a .630 lift on a 110 seperation.

ugh, it's carbureted though.

Well, I know so little about Fuel Injection I'm affraid to even post a picture of it, I't might cause a ck. engine light to come on.

If you Know Fuel Injection may be you could start a thread on it, I have a lot of questions.

[Daniel Haught]

I'm no fuel injection guru, but it's just sad to see such a well developed FI engine like the LSX series with a cast manifold and carburetor on it.
They can make so much power with the stock type manifold and FI that it's not even funny.

[rookie]

I've just recently started messing with learnig FI. I've got a 6.0 liter gas 2001 Chevy 2500HD figure all I can do is start with basics and go from there.

I did not know carbs untill I started working on them.

[automotivebreath]

That carburetor looks more than a little out of place up there. It seems like
using the fuel pressure to atomize the fuel in a injector would have advantages.
Something like this would look look more at home. In addition it would be nice
to have the ability to tune the runners to a specific point in the power range.
