Hello, I've been viewing this site for quite some time and I have found a lot of useful information here. This is my first post here, so bear with me.

Obviously I have a 95 truck, not a Camaro, but it has the same TBI setup that Camaros do. Its has a 350 and I finally got the exhaust the way I want it, with headers and such. On the intake side, I removed all of the OEM cowling and put an open K&N air filter on it, as well as a TBI spacer. Other then that the thing's stock.

Now, to my question. I've had this 670 cfm Holly throttle body sitting around for a couple years now and I finally acquired the flat connector to install it. I figure that since I'm changing the throttle body I might as well throw on a better intake manifold. I'm running on a budget so the Edelbrock TBI Performer is a little out of my range. On Summit Racing I found a nice Weiand carburated non-egr intake for a good price (I'm going to use a TBI adapter plate). Being that its non-egr, I suspect that my ECM will throw a code. Is there any way to fool the ECM on this point? There is also an EGR Holley Manifold that is a little over $30 more. Its not much, and my budget could probably handle it, but is keeping EGR worth thirty dollars?

I was also wondering if anyone else is running the Holley 670 TBI. Though my research I keep seeing that people are always having issues with. I guess they always either run too rich or too lean.

 

Any thoughts?

 

I would not use a 2" TB on a engine with less then 280fwhp, that's around were the stock TB starts restricting.

Adjusting the idle and some tuning will be required with the 2" TB.

A few treads up the bad holley injectors are described. https://www.thirdgen.org/forums/post...437-post5.html

Passing emission test may become a issue without EGR, depending on cam too.

If you have the stock heads, EGR does improve MPG a little, note it is only active during idle and light trottle cruising.

EGR can be desactivated permanently in the tune, if not required.

 

Emission testing won't be an issue since my state doesn't test 1997 and older vehicles. So, basically I would just have to get a chip burned to deactivate the EGR? I might hold off in that case since I was also looking to get a cam. I might as well get a chip when I have everything I want, done to the engine. I would like to put a new manifold on it soon though. I guess I'll just remove the check engine light for now, in that case.
