I'm thinking about installing the Edelbrock "Performer" intake #37011 on my 75. Main reason I want to do this is because the paint cooks off where the crossover passages are on my stock manifold, and looks terrible. I have a couple questions:
1. Will the installed height of the manifold present any hood clearance issues with the stock air cleaner and air intake hood seal?
2. I'm planning on keeping the original EGR valve. Summit recommends a #1476 adapter, is it required to get the valve to fit?
3. The description says the manifold will work with late model choke setup. Mine uses a tube assembly that loops around in the opening provided, and connects to the carb air horn and carb mounted choke coil. Will it fit the new manifold? I see a different setup has the choke coil mounted into the opening with a linkage rod attaching to the choke.
Thanks for any assistance, I've never done anything like this and want to get it right so I'm not waiting for that one part I needed...
I dont know about the choke as I have an electric choke on my carb,but the height will not be an issue.I have a 74 with the performer and Im useing the stock air cleaner with no fit problem.
Steve, have you thought about blocking the crossover?
Rudy, good idea. That would stop the cooked paint problem.
The other ideas about powder coating and ceramic coating were very good as well, thanks guys!
I am honestly thinking about doing this Performer thing anyway. I really like the looks of that polished aluminum manifold, thinking I might as well get me some L-82 valve covers as well.
I did a little more checking with a phone call to Summit. The EGR adapter is only needed with the Edelbrock EGR valve, the GM one will bolt right up. Guess maybe I'll take my chances with the choke situation and deal with that as required. Looks like I might pick up a little performance with this setup, maybe I'll be able to stay with you a little better on the next cruise Rudy!
You can use the stock choke (though you may have to use a hot air tube from Edelbrock) or you can convert to electric. To convert to electric, there is a kit you can get at NAPA. Basically, it is an electric choke for a late model Q-Jet. Remove the cover (3 screws), pull the innards out, install new innards and new cover. Don't use the old gasket since the new cover has to be grounded to work. Then wire it up to a switched source (I went under my dash to the IGN feed on the fuse box).
