Stupid Edelbrock install question

The fuel can be worked around; both Edelbrock and Spectre offer a banjo fitting fuel line kit to bring the fuel connection to the front, or you could just use the female flare fitting from the Stude carb and bend a new piece of 5/16" hard line between the carb and wherever you cut the hard line from the fuel pump for an inline filter (you did do that, right?) but at least the Spectre line requires a minor tweak to fit on a Stude intake, even with a 1/2" spacer. You can use the threaded power brake connection for the PCV and block off the PCV connection in the front, as the Stude manifold has a fitting for the power brake on the #7 intake runner. The Edelbrock manual discourages this but I don't see a real problem with doing this, the factory Stude AFBs used the same fitting for the PCV. The ported vacuum advance connection is actually in the exact same place as the one on the Stude AFB but it is a hose barb instead of a threaded fitting, so you either have to drill out the hose barb and tap the hole with a small pipe tap to use the factory fitting, or else just run a hose back to the vacuum advance (I did the latter put some heat sleeving over the hose to keep it from burning on the intake since I'm using a Thibeault distributor that has a hose barb on it as well.) Just block off the unported vacuum fitting on the driver's side unless you are using an R1/R2 kicker, in which case you can just use a hose there instead of running the hard line from the ugly tee on the manifold (which you can get rid of now.)

You will either need a 1/2" spacer to clear the throttle linkage from the heat crossover, or else you will need to zing the GM auto trans kickdown bit off the linkage with a cutoff tool.

good luck,

It seems that all of the connections are backwards.

thinking, dummy, of course you have the carb on backwards,

connections for vacuum and fuel? (Feeling Stupid in CT)

Almost forgot to mention, if you have an automatic trans, you will need to use the large hole in the throttle linkage to hook up to the factory Stude linkage; I had to use some well chosen washers to hack together a little bushing-like assembly. There is a hole in there that looks like it will work well, but the trans won't get the full signal from the throttle pressure linkage then because that hole is closer to the throttle shaft than the one used on the factory Stude AFBs. The big hole is pretty close to the correct distance. You can use the smaller hole with a stickshift but you might need to adjust the OD kickdown switch and the throttle will open wider for a given amount of pedal travel.

I tried that smaller hole... had to drill it out to get the bolt through. That was interesting to drive. It's so close to the pivot point that I was either at idle or at about 3/4 throttle, no feathering the throttle. The big hole is the right one. Lowes does sell a nylon bushing in their specialty parts bin that works great for a spacer.

AH- HA! WHS!! (wrong hole syndrome

I agree with Nate. In fact, I called Edelbrock when I was setting up the Edelbrock in my Champ truck, and they agreed that there is no problem in using the rear port for the PCV.
