    Anybody running one of these? If so, what are your impressions. If you have a better suggestion, Im all ears too.
    I also might need someone to take me by the hand and go through how to install it. Getting it on and off looks pretty easy but I read a post about sealing issues (gaskets, where to put RTV). Which bolts need a little RTV/Teflon to keep coolant from comming out. I found out about that when I had to loosen one to do a valve cover job. Thanks for the help.

    Oh, by the way '82 Silverado, crate 350, th700r4, a/c, cruise (well sorta, some of the parts are there), no emissions stuff or EGR, just vapor canister stuff, and a Q-jet w/ electric choke.

    I installed one on my 79. It does feel it takes off a bit faster, but not that much. Maybe because I took a long time to fine tune the new q-jet I installed at the same time.

    Installation was easy, it's as simple as removing the carb, manifold bolts, manifold, clean contact area well, and reinstall everything in the reverse order using new gaskets. The manifold included a sheet with directions and the right part numbers for the gaskets.

    The only problem I found was that the holes in the manifold did not align perfectly with the head ones. I had to enlarge them 1/32" each so I could bolt it properly. This could have happened because I ordered my manifold from ebay (the q-jet too and it had debris inside which gave me a real hard time tuning it) or because I removed the old one when the engine was still warm.

    I say go ahead with it. This was my first "mechanic" job and made me feel proud of myself when I was finished. Visit <A target="_blank" HREF=http://www.edelbrock.com>http://www.edelbrock.com</A> for the right application. I think the non-egr one is the #2101.

    Good luck. If you encounter any difficulties, please contact me.

  4. I think they work well in conjuction with a cam and headers. on their own i don't think they do much for performance. I've had rigs with stock manifolds and a cam and headers that performed great. its the whole package that will really show you results. if that's the direction you are going then great- buy each component as you can afford it. and yes, get a performer or wieland stealth dual plain for good flow at low end. you can get either one with a spread bore pattern so you can keep your q-jet.

    Thats what I what Im beginning to think too. I might wanna cool it for a while and get a cam too as long as I have it apart. I may just leave it, I've heard the cams in the crate motor have a little more guts than the regular one because they didnt go emission crazy. Maybe a set of Heddmans and get my 3.73s in place (have 3.08s now) and I'll be flying. Thanks for the input!

    I run the Performer intake, with the Performer cam/lifter kit, Hedmans and 3.73's, and it seems to be a very good combination.

    One of the reasons that you might have had to elongate the holes is because of material being removed from the block or heads and moving them from their stock location.

    One of the mistakes people make is to put on a high performance manifold and not modify the exaust system. Most all Performance manifolds work best with headers and low back pressure mufflers.
    Its a waste of money to put on a new Hi perf. manifold on a stock exaust.
    So if you haven't improved your exaust I would recomend spending the money on headers and some good muffs. And adding the manifold later.
