OK, so this is my first question to you guys who know a lot more about these old fords than I do. I have a non branded 2x2 49-53 intake with a nice set of 94 holleys on it I intended to fit to my 8BA. I have just noticed that the OEM single carb intake has 9 mounting bolts a side (and one non-utilised hole, I ***ume, a side) but the 2x2 intake only has 8 mounting holes a side. Also, the oem has two pipes at the front driver side, LHD . One oil filler tube and a breather tube while the aftermarket has only the filler tube (drivers side) and a PCV on the p***enget side. Also the genny strap bracket which came with the aftermarket Powermaster PowerGen Part #82021 looks as though it may take a little grinding of the manifold gen mounting lugs to fit. I cant use the OEM generator mount as the upgraded gen is of greater diameter. Will it fit? Is the # of mounting holes an issue? Hope this makes sense. Thanks in advance.
The pipe other then the filler tube is the draft tube. A pcv can be placed in the hole. You can find aftermarket alternator brackets to fit your aftermarket intake. you can also get a shorty alternator instead of grinding off a chunk of your intake. Aftermarket stuff is made to fit many applications. This is a picture of my 8BA w/oem intake and pcv next to the filler/breather tube and part of my PowerGen w/bracket.

Yeah mate, I have a "PowerGen" that is shorter but is larger dia than the oem genny. The "PowerGen" brand genny came with a mount but it wont fit the 2x2 manifold. To wide by about 1/16" but I can work with it. Im more concerned about the # of mounting holes in the manifold. The holes that are there align with the engine, there are just fewer of them. Thanks for the reply
My Edmunds Racing manifold has seven mounting holes on each side Same with one of my other twin carb manifolds.
Does this affect the fitting or are the extra mounting holes in the block just made redundent buy the manifold ? Cheers.
Could it be that one of those manifolds is made to fit a pre 1949 Ford V-8? Hence the hole differences.
Ford reduced the number of bolts needed to hold the manifold to the block when they introduced the 8BA (cost cutting). I've never had one leak, so I guess it wasn't a bad move. I would imagine that the aftermarket manifold makers modified the tooling for the early manifolds to use for their 8BA manifolds and the extra holes came along for the ride. BTW, that Edmunds manifold is kind of special. Although it is set up for three bolt carbs in the picture, it can be modified to use 4 bolt carbs, by drilling and taping the rear two holes on each carburetor pad. I believe it can be used as is for the Mercury 4 bolt Holley carburetors, Small base Rochester 2G's (bigger and better) will also bolt on, but the throttle bore should be increased to 1 7/16". The resulting setup will flow about as much as 4 97's with half the trouble. Also, do not try to use a "Super" type manifold (widely spaced carbs) with progressive linkage. Dual carb manifolds are a little more complicated than one would initially think. There are actually three different types defined by carburetor spacing. There are "Supers" with the wide spaced carbs, "Regulars" with the carbs closer together, and "Rear Biased" manifolds with the the carburetors moved to the rear of the manifold.
Someone is paying attention . Years ago i put two of those big Towering Inferno carbs on just for fun. Looked impressive for about 10 minutes, then it all went back on the shelf.
