Choosing between intake manifolds

My car had the Edelbrock Performer 289 intake on it but a have a vintage cobra intake, which should I put on? I noticed there is no water temp sensor location on the cobra but I can get a thermostat housing with one. Also is there a way to clean the intake to make it look new again?

There probably isn't a single horsepower difference in the two. "Back in the day" , the Cobra intake was only 20-25 better than the stock iron four barrel intake. The Performer is about the same. now the Performer RPM or Air Gap is a bit better than the old Cobra. The Cobra has the WOW factor though. The modern Blue Thunder Cobra repop is very good too. I've run almost every 289-302 intake out there in my 50+ years of racing them. Power is limited by cylinder heads more than any other part.

Yeah I was thinking it would just look cooler. If performance is the same then the cobra is the way to go. My only concern is itís a little taller and may have a clearance issue on the stock hood

Randy covered it.

I've had the best success with steel shot blasting intakes (Steelabrator). It peens the pores of the aluminum closed and keeps it looking good for years. Many engine shops use them. Second best is bead blasting, but it doesn't last as long unless you clear coat the intake.

Nothing worthwhile is ever quick, cheap or easy, those that can't do, complain

I bead blasted my S2MS then polished the COBRA letters.

I have HiPo heads to go with it. Was thinking of getting a set of new aluminum but like you said I think the wow factor is greater with the HiPos

I have used a wire wheel with good results before...though not on a carbed v intake...but it works well enough with cast aluminum EFI intakes...just use a softer wire wheel...not a braided wire wheel...but media blasting will do the best job...I always end up being unhappy that I cant get in some nook and cranny and end up painting the thing with cast-aluminum color paint...then it does look new.

Now that I see a picture of the manifold you have , I see it has a Shelby engine department modification ( the side to side "step") machined into it. This was reserved for "race manifolds" only back then and is also with the water temp fitting hole isn't drilled. Because of this "revelation" LOL you would be better off using the Cobra intake. You could drill and tap for the water temp sender too . I see the boss is there in your picture. I believe that should also have ported runners since it was a race piece. Still fine for street use. RE your hi po heads , IF they are also ported they will be fine. If not , aftermarket aluminum heads will make more power. A ported hi po head will flow about 210-220 cfm at BEST and nearly every aluminum head flows more that that "out of the box". If we had something like that 50 years ago , we would have left the Chevys in the dust and been waaaay further ahead now. We didn't get a true performance head until the late 80's. Now there are 30+ different Ford small block aluminum heads to choose from.

I'm going against the grain here. Put on that Edelbrock, clean up the Cobra and then ship it to me.

I was thinking I would use a thermostat housing that has one built in.

If you use the S2MS intake be sure to locate the torque sequence chart. It is very specific...and delicate. I have a hard copy, but donít recall where from.
