Last time I posted I had questions on an edelbrock intake. I basicaly had an intake that was supposed to be for a 351C and it seems like it is something else. Although the intake fit over the engine, the bolts don't mate flat to the surface of the intake. Since I decided to get a new intake and not deal with the one I currently have, the question is, Will the Wiand work better or the Edelbrock? I currently have an RV cam, a holley 600, headman headers, and a conversion kit for electronic ignition. I don't know if the weiand will work since it is for 2500 rpm I believe and I don't know if the cam can match up to that. The last time I got coments that people liked the weiand better but did not mention their setup. Will this be an issue for a daily driver? I just want to be able to step on it when needed but be tamed enough for city cruising and gas of course. I plan on mating it to an AOD for fuel purposes. It will go in a 74 F100 LWB 2wd. Don't know what else I can add. I had to put this off for a while since I went on vacation for a month and ran out of cash. Now it urges me to finish it up and enjoy it. I get pretty excited just watching the truck and thinking what it will do when its all complete. Thanks for your help.................

 

if your block has been decked and/or your heads shaved, the geometry of
where the heads mate to the intake will have changed, causing bad fit.

if this is the case, any new intake will have the same problem and also require machining.

 

When heads are milled they usually take something off the manifold mating surface of the head to keep the geometry correct. If a block is decked, that same process of removing material from the manifold mating surface of the head should also be followed.

By removing material from the head, it prevents having to modify every manifold that is mated to the motor.

 

The block was milled 30 over but that was it. No work was done to the mating surfaces. I was wandering why the surfaces looked the way they did comparing them to pictures I had seen on magazines where the block and heads looked freshly cut and the ones on block did not. Is that recomended to do on this particular block and if so what is an estimated cost for this and what else do I have to look ut for?

Getting back to the original question: The only difference I see on the intake is that the bolt heads and the mating surface on the intake have about a 30 degree angle between them. Actualy they had it since I decided to even it out with a file. I will try to post the pics of the bolts mating to the intake tomorrow. Is there another block that has the same geometry as the 351C with the exception of the angle at which the bolts hold it in place?

 

Do you mean it was bored 30 over? Boring will not affect the fit of the intake manifold.

Are you sure you have a 351C Motor and a 351C intake? You might have a 351W block and a 351C intake, or a 351C block and a 351W intake.

 

Yeah, it was bored not ground down on the block or heads.

I know for a fact it is a cleveland and not a 351w. It came off a 73 mustang MACH1.

 

I had this same problem when I put my 351C together with 400 heads and an Edelbrock manifold. It comes down to this. Do you trust parts that have been floating around for at least 30 years or Edelbrock? In my case, someone had angle milled those heads at some point and caused me lots of grief trying to figure out what was going on during my first motor assembly experience. Fortunately I also had some 351M heads I knew were original to play with along with the wisdom of this forum. I know it's frustrating, but I'd have those heads and/or block remeasured or if you have other heads, try test-torquing them onto your C and re-fitting the manifold.
30 degrees is a lot, does your manifold fit into the motor assembly and the bolt misalignment is the only snag? They did put Windsors in '73 Mustangs, right?

Pictures would help,

Coming out of a Mach 1 doesn't mean anything. My Dad's 72 Mach 1 came with a 351 W.........Both engines were available.....

 

Have got the numbers off the block to see what engine it is ?

 

Don't have the #s of the engine....... Havent looked them up. The valve cover sticker said it was a 351c........

Also, the machine shop that did the work took it as a cleveland and ordered all the internals for a cleveland.

The engine seemed to be all original when I opened it up. Can't remember the mileage on the car but there was no trace of ever being opened up so I'm assuming all parts have to be original. As far as the fit of the intake to the engine, everything seems to fit right in place even the bolt alignment. The only problem is that the bolts have that angle I mentioned. I finaly got the picks. You can see them on my gallery. The only problem is that you wont be able to see the angle since I took it off with a file but you can see where the bolts went sliding to one side and broke the manifold wall where the bolt goes in.

I also looked up the vin on the car and that's what it came up with.

 

Just looked up the specs at ( http://classicponycars.com/ )for the 73 mustang and it seems like the only 351 available that year was the cleveland as a 2v and 4v. Mine is a 2v. I thought I'd seen this specs before just could not remember.

 

Anyway, anyone have any input as to the performance of these two intakes (weiand and edlbrock) on a cleveland 2v? I also recal someone mentioning here that they had used both before and liked the weiand better but did not mention the specs on the engines.

 

Is your manifold for a 2V Cleveland or a 4V Cleveland?
Since you have 2V heads, you need a 4 barrel manifold for 2V heads, not 4V heads.

Although I have never used one, in most cases a Weiand manifold is better than an Edelbrock.

 

Whacky. You've got 2V heads and a Performer 2V manifold (the block sure looks like a C as well), the pics confirm it. This is exactly what I had, except for the M-block heads. I still suspect someone shaved your heads or block mating surface an an angle...that was my case with the 400 heads that gave me fits. Do you have the original iron intake to test fit? 2 or 4 valve heads will both line up the bolt holes on a Cleveland, the ports just don't match.

I had a buddy's C block, 4V heads, a 4V Edelbrock intake, a 4V iron intake, my Edelbrock 2V intake, my 400 heads and my 351M heads to try different combos and I almost lost my mind chasing the misalignment but did manage. Don't do any more filing or grinding on those intakes, there has to be a better solution for that misalignment. Be patient yet determined, I've been there.
