To be fair the new four cylinders, six cyclinders like the GTR's vr38dett, and overhead cam v8s are loving huge. The lsx is basically 2/3 the size of the VR or a coyote.

It's ridiculous. Long live the pushrod.

Holy crap. The pushrod Chevy looks like a toy compared to whatever it's next to.

I guess I never realized just how much bigger OHC made an engine.

That's an LS3 next to a Coyote. Both equally dressed.

A lot of the truck engines are iron block and therefore much heavier.

I've read that it's only about a 60lb difference. Enough to matter for a balanced track car, but it's not like an old big block with iron block, heads, intake, and so on

A 6.0 destroked to 334ci. Uh, thanks for making me do unit conversions guys.

6.0l = 366 ci
334 ci = 5.47 l

an LQ4 is 364cid

The F22 and F23 use the metric 60 degree V6 bolt pattern, which is also used on the LS4, and the Ecotec 2.0/2.2/2.4. I don't know what other engines that pattern is used on, though (I assume all LSs use it).

Nope, that's one way the LS4 is special. All the rest of them have the classic SBC bolt pattern (missing one bolt and different crank depth though), which is the same as the 90 degree V6 pattern.

I think I have read that the LS4 is a bit shorter than the LM7 on which it is based, but I don't know if that's a difference in the block, or if it's all in the accessories. I'd imagine the mounts are in a different spot, too.

That's all I know about the LS4!

E: Internet says the mounts, crank, block length are different, as well as it not having a starter boss (since the starter is on the transmission, apparently)

Uhhh.. So his entire problem is that you put LSX 454 rocker covers on a 454ci engine that's actually an LS3?

Yeah it looks to me like he thinks OP is trying to pull a fast one by using a more pedestrian block (:rolleyes:) than his valve covers suggest, even though it should make for a better build overall

I mean, he sort of has a point because he's using LSX branding on something that's not an LSX, but it would be slower with an iron block anyway so who even cares. Just don't put those valve covers on a stock 4.8 or something.

The main difference, besides the block material, is the deck height, right? I think I remember reading something about problems associated with running too much stroke in a short-deck block and exposing the skirts, but this doesn't seem to be OP's first rodeo

Do you guys not do the mid-week test-n-tune nights? Seems like that sort of thing would be about perfect.

Where can I get thick posters printed affordably? I want to print a flat pattern and cut it out to test fit on the car before I laser my sample at the metal shop on monday and start forming.

Everywhere I look is limited to 48" and my pattern is like 24x60"

Sign shop, maybe?

...worth not owning as good of a car?

The question is: not as good of a car for what? If you want a drag car to go as fast as possible, the S2000 was never the best choice. Personally, I was the most attracted to the S2000 when it was mostly stock except a loving ridiculous motor, because that's what made it a crazy sorta-sleeper to me. A tube frame drag car with a Camaro body on it or a S2K body on it is kind of a different thing, but it satisfies a different need. Do you want fun/quirky, or do you want as much go-fast as possible?
