I would not waste the money on the intake. Edelbrock sales one but studies show not much is gained.

The HSR will be interesting when they get it done.
I think it's exactly what an LT needs, tunnel ram with longer runners.

There are lots of single-plane conversions out there,
not a whole lot of hard numbers proving their effectiveness though.
Certainly not worth it unless you're going to spin beyond the factory PCM's ability.

The Edelbrock aftermarket manifold is worthless.
The plenum is too small and the design actually produces LESS horsepower.

Your best bet (IMHO) is to use a stock plenum and have it ported by the same people who do your heads.
Bigger TB holes will allow you to use a 58MM TB, you can raise the roof a little behind the injectors,
runners can be made slightly larger (to match the portwork on the heads) and the area behind the TB can be
tapered to improve flow towards the runners (lots of material to remove here).

According to the GM High-Tech Performance magazine test, the Edelbrock does not lose power compared to the stocker, on a stock engine. But it does not show enough power gains to make it worth the price. It will be interesting to see what affect the reduced plenum volume has on larger, highly modified engines.

I just read that article! The edelbrock is not worth the money on a stock engine. Did anyone notice that the a/f ratio was taken to 13.7.

that is a very nice tall intake and yes it is a very good reason to get a cowl hood.

it fits w/o a cowl they say, tightly though.

This would give the lt1 more low end, for starters, that it is lacking, which many complain about. But I still think the lt1 has impressive low end on it's own, even compared to newer mustangs and mach 1's. My GF's mach 1 doesn't have the low end grunt the camaro had stock and certainly not now. But yes, it can still be improved upon further.

That intake looks bad ***. But I would put the extra money into the heads and have the stock intake ported by AI. On advanced inductions site there is a ta that ran a 9.55 NA 1/4 with out a tunnel ram intake. It would be interesting if AI could git ahold of this intake and put it on that car after being ported and see what it does; I don't think you will see much of a gain, but I could be wrong.

Sexy ... Any idea how well it worked VS the stocker (or even a ported stocker)?
