318 Rebuild Questions???

[74Runneer]

Im in the middle of a semi engine rebuild. Im putting new heads and intake on my 74 318. The heads are #302 casting swirl port heads. I'm putting an edelbrock performer intake instead of my edelbrock street master intake. I pulled heads, intake , and accessories are off today. I cleaned the block a little bit and sprayed mopar blue engine paint where the eye can see and ill pick it up tomorrow.


My question is: On my old intake there was this oddly shaped half inch thick plate that was on the drivers side right under where the linkage would be. My new intake doesnt have the screw holes tapped yet but it does have the spot where it should go. Is this something for the choke? Do i need this anymore? There are no wires or anything going to it.

My Second question: There is this fitting that was attatched to the new performer intake. There wasnt anything like it on my old intake so i am confused?? Its on the drivers side towards the back of the intake. Hmmm?

Final question: Can i get rid of the the header studs that are in the heads? They are off of an 86 dodge 318. They have studs on the first and the last header bolt holes. Due to clearance issues id like to get rid of the studs and get some normal header bolts. Are these studs jutting into the some passage where i need to keep them? Thanks!

The plate sounds like an EGR block off.

Not sure about the fitting on the Performer intake. Could it be for a vacuum accessory?

I'm not sure if the studs hit water on those but even if they do you can put bolts in. Just put some pipe dope on the threads or some kind of sealer in case they do hit water.

Okay I found out I can get rid of the erg plate because my new intake hasn't been tapped yet. I'm not gonna worry about that fitting on the back of the intake yet.But I'm soooo frustrated right now. The heads headers valve covers and intake are on. All is well there except my intake! My friend had the intake bolts and mixed them all up and now I can't bolt the intake down because some of the screws are too short! Are intake bolts all supposed to be the same sizes? Can I just go to napa and buy intake bolts that will fit it? Uhh! I've been messing with the intake for the last 3 hours and I can't get it right.*Also my ac bracket and alternator bracket aren't lining up right anymore. With some force I can get the alternator to work but the spot where the ac bracket bolts to the intake is way off, maybe half ab inch to an inch. Did edelbrock streetmaster and performer intakes have different bolt locations?

You can sort out bolt length by dropping the bolts through the intake holes and seeing how much thread sticks out. Yes, you can get grade 5 bolts from where ever that meet your needs.

Try loosening up the rest of the bracket bolts and get them all started before you tighten anything.

Since no photos accompanied your original post we can only provide you with educated suggestions.

I would be concerned with belt alignment for both the Alternator and A/C compressor. If they do not run true, you will experience problems with each later on.

I'm not getting the A/C bracket bolt holes being off by 1/2 to 1 inch. A/C mounts I have seen, mount to the front (i.e.: water pump bolt holes). Are you indicating there are mounting points on the intake itself that are not the bolt holes going into the head? As Meep-Meep stated, (it's rule #1 in my book) if you haven't already done so, put everything together loosely 1st to ensure fitment.

Posting photos of your dilema does wonders in getting you correct answers. What seems clear to you as a verbal description may not be to those trying to picture it.

Just another car guy trying to help...

The front and rear exhaust bolt holes on the head do go in to the water jacket. I just replaced the studs with header bolts on my dads 318 just made sure to put hi-temp thread sealer on those bolts.

Okay Ill post pictures later today. Ill try loosening everything up and then going from there, that should help. Thanks!
