Fatboy almost has hisself talked into a flathead for my next project, but I'm new to these motors (sbc fan) and have a few questions. The pic I'm showing was taken directly from the TV. It's Doane's flathead from the Americon Icon Hot Rod series. Is there a benefit to running this style generator mount off to the side? I noticed the carbs line up more in the center of the manifold with this setup. Who makes that generator mount? What brand intake is that? Do I have to run an electric fan with this setup like Bruce Meyers did here? inquirin' minds...
It gives the front carb more room. If a float sticks it doesn't poor gas directly into the brush area of the generator and start a fire. With 3 2's I believe the generator must be moved for clearance.
Well I am interested in the discussion as I'll be putting together a Flatty for my '33 this upcoming fall. One reason for this type of generator mount is that with out the use of a high rise intake such as a PM7, Slingshot, Thickstun, or Weiand the generator would interfere with the carbs. I am interested to see which style intake is earlier. I have a polished Edelbrock Super Dual that has the same type of generator mount as the one above. Then I have another intake that is on my flathead which is also a Edelbrock and it has a provision for the generator to sit front and center with perhaps the fan running off of it? No you do not have to run a electric fan as long as you ***emble the right parts and use a 59a styled engine. But I know nothing so like I said, I am interested in this discussion.
I believe the mounts come with those intakes. If you are interested in a polished Super Dual (polishing was done 40 years ago) with one of those generator mounts I'm going to sell both of my intakes as I am looking for a Weiand High Rise. Here are both styles.... Also I just stumbled on this site and it seems like a wealth of knowledge. Check it out big guy! http://www.ozrodders.com/forum/viewtopic.php?f=24&t=13612&p=162322
The intake in the top of the pic. has the front carb moved back to clear the gen. Saves moving the gen. to the side.
Think your other questions have been answered for the most part... but you can easily run a mechanical fan with that sort of setup.
I've been working on getting a mechanical fan setup in my AV8 and am having fitting issues. How traditional is an electric fan? What year is the electric fan getting used on hotrods?..........early 50's
On mine i was dressing an 8BA as a 59Ab and used an offset generator mount that attaches to the intake. then reworked a 49 merc fan to fit that. that gave me wide belt. Hope this helps John
I think Offenhauser still offers those generator mounts, Speedway probably has them, also see them on e bay regularly.
The Hot Rod Company offers the offset generator mount, they offer a drivers side and p***engers side version. http://www.thehotrodcompany.com/shopnow/show_item.asp?product_id=5601093
Speedway has both the Offy gen bracket and the fan bracket. Electric fans are not really traditional. We didn't see they wide spread use untill the eighties or nineties. I never noticed the one on the Spencer car, sorta' suprised!
that mount is for the intakes that do not have provisions on the front for a gen mount. there has been dicusions about them in the past about how to mount them to 8ba heads as they colide with the water neck. if you use longer bolts and some sections of tubing as spacers roughly .5-.75 inch tall they will clear. here are the 2 "left and right" from speedway mounts http://www.speedwaymotors.com/Offenhauser-1937-48-Flathead-Head-Mount-Generator-Brackets,795.html ive read that H&H sells a navaro mount like the one speedway sells. IF you have the front mount on your intake then you could use one of these http://www.speedwaymotors.com/Offen...erator-Brackets,796.html?parentDisplayId=4242
i dont have anything intelligent to add, but i worked at the Petersen this summer and helped detail the car and engine and set up with the photo/vid shoot...
Apples, oranges, and bowling balls! OK...the fundamental starting point is '32-48 style pumps or '49-53 (which can be swapped with minor work and an early distributor). The picture shows '37-48 pumps that put belt as close to the block as is possible...this setup is often the only good one for an early ch***is because it allows space away from radiator. It requires front distributor, still the easiest route to a good ignition. Performance manifolds like super duals and triples cannot clear the stock generator location. The type of side mount shown came in 2 varieties, one swinging the generator up close beside manifold (best for belt wrap), the other swinging it out to clear the low hoses used '39-41. Almost all manufacturers made these, misleadingly labeled left and right. Manifolds with no gen bracket are made for '39-41 with crank mounted fan...no need for that bracket there. Manifolds for other early years retain the bracket (in a couple of formats) to allow either top mount '33-39 or slightly lower '42-8 extra sheave fans to be bracketed (requiring some tinkering in either case). '49-53 pumps move the belt away from block farther, necessary to clear the slanted distributor. This allows a greater variety of manifolds (but not all) to fit a generator in middle. Most still require offset brackets, generally a sort that bolts to old gen bracket rather than head. Less clearance for early radiators. I think everyone considered the offset gen necessary for best manifold design...the close-set ones were slanted toward the street dress-up market as installation of a super dual had enough h***les that an inexperienced rodder was not going to be driving his car to work after the weekend thrash! Early setup with fan on gen (you mount fan with an extra gen cut down to nothing) can run with a single belt really close to engine. Using the entirely separate fan used '42-8 and '49-53 requires second belt and more space.
