From what I have heard thru the grapevine,the stock LT1 intake is
pretty good. There are many other areas in the LT1 package that
are better suited to changing than the intake. For example there is an
LT1 corvette in NHRA stock eliminnator, out in Washington state, that per rules must use a non ported intake manifold with a non modified throttle body and it has run 8.90'S on a good day and thats in the 1/4 mile! ed

But that car does have some serious cash poured into in many other ways..a aftermarket throtte body would still work on a stock lt1 intake right?

From what I've read on here the stock throttle body is okay until u start doing more serious engine modifications.

Port and polish the LT1 intake and install a 58mm tb.

Yes you can add an aftermarket throttle body to the stock LT1 intake,
before you see much of any gain from it, you should probably
have ported heads,possibly a cam and headers.ed

Unless you have something exotic in mind, there are really no intake upgrades out there (the Edelbrock certainly isn't an upgrade). Doubtful you need a TB either, but we don't know anything about your setup, goals or what you are doing.

Unless you have a modified engine and have run out of things to buy, do not bother with either a new intake or throttle body. They are just not worth the headaches.

But, once you do convert to a single plane, you can run all sorts of cool LS1 throttle bodies

I agree with ShoeBox and ShowNoMercy. However, you have to start somewhere right? Generally a intake or any upgrade has to be complimented with a supporting upgrade as stated. Come up with a plan and think about your intentions and purpose for the car. Let us know so we can be of assistance.

The stock LT1 is a great manifold, which is why there are no aftermarket manifolds.

As for the bigger throttle body, unless you are really sucking air, its not needed.

If your gonna upgrade your intake soon then to what? We're all waiting to hear your engine/car specs and performance needs. It becomes a waste of time to share information with someone that doesn't even have a chevy.

Until you have major head changes, you really don't anything on the intake side. MHO.

Try a CAI first - i like the MOROSO "honker" <$200. Nothing out there gonna help u more right now for less than price of a good cam and vlv springs.
But wait. How do use a "Y" pipe with "true duals"? This sounds more like bogus post and until u start talking the truth your on my ignore list mister.
