Here are a couple that I dug out of the dungeon to mockup for the Hemi project (the long 10 year one!). I originally was going with the polished 6-71 and dual blower carbs - but now I'm converting a MFI hat injector over to EFI (using the Holley Dominator ECU). I've got a few options - will need to determine whether I run the 6-71 or put the 8-71 magnesium Bowers on it. I will be running the Crower Goliath 8-port injector - as the smaller butterflies are ideal for EFI and I'll probably only run one side of them. The car is a mid-60's style 34 Ford - fuel comp coupe type of build. That damn magnesium Bowers keeps calling to me though . . . so who knows . . .
Dammit dale you shouldn't be showing such magnificent works of art for me to drool over I know if it were me it would be a mag bowers and a crower eight port no questions Sent from my iPhone using The H.A.M.B. mobile app
Yeah Randy - I keep thinking I'd like to go with the mag blower - that would be probably about the best blower for the last of the fuel coupes. Also, the Crower is mag - so that kind of has me thinking. I wish I could find a set of Donovan 417 valve covers in mag . . . but I was damn lucky to get the aluminum ones and have never seen a set of mag ones. I do love the look of a Enderle Bug Catcher - but everybody has one of those and they are hard to run on the street (too much air when you barely crack the throttle plates) - hard for off stop-light transitions. This Enderle is our "spare" Alky one from the FlatCad project - have never used it (was just sitting in a box in my basement).
Started collecting parts to put together another blown Olds. Looking for a vintage Weiand drive setup to go with the Weiand manifold, top and bearing plate..
Can I ask a favor? Could you post some more pics of the howard chain parts? As many as you please. Some flat on pics I can measure from? I build models sometimes, and i'm in love with howard chain covers. Awesome looking pieces of equipment!
2017 Hey M, Here are some photos and film on the latest version of the Howard cam "Twin Bear" race car that was associated with Jack Chrisman. I was able to film it back in 1959-60 at Lions Dragstrip and it was a crowd favorite every time it made a run. It was very Loud and Fast... Jnaki Jump up 58 years later and it was sitting in the empty building getting prepped for the grand opening display of the Price Transfer Lions Dragstrip Museum. I was fortunate to be able to take some photos in those preliminary days and the actual event in June of 2017. from another post: Hello, Nothing says chain drive than the original Howard Cam Twin 671 SBC FED from the 59-60 era of drag racing. The Jack Chrisman driven FED won a lot of races at Lions and other local So Cal race tracks. The “Twin Bear” as it was called, tried many versions of streamlining, starting with the well formed aluminum sheet and the famous custom “plywood” panel. Then eventually, a well molded metal panel covered up the front for the Nationals. My brother was a Howard Cam fanatic. Starting with the full race Howard Cam and kit, flywheel, trans adapter, and if the fancy Isky Gilmer Belt Drive set up for the SBC did not just come out for our motor (with our special deal), the chain drive was our first choice. Jnaki The chain is a crude but functioning way to attach all of the drive pulleys. It is also dangerous as it may break and fly outward, so, the need for a fully enclosed cover. The chain is as strong as the weakest link…We all remember our bicycle chains breaking a link and flying off. The downfall of the enclosed chain drives (or any chain drive kit) was the introduction of the wide industrial Gilmer Belt kits on aluminum pulleys. That introduction was not for a few more months later in 1960. But, sometime in April-March of 1960, Reath Automotive started marketing a chain drive for competition use only. The difference being a comparison to narrow belts that did break…think fan belts stretched to the max. They still had belt driven superchargers for the street in kit form, but this new chain drive was for competition only. mudersbach vs howard cam twin lions 60917 set up days taken at the Lions Dragstrip Museum The little "L" brackets on the finned cover are mounting points for the custom plywood sloped nose shield. chrisman corner 62417 A great find of one of the earliest photos of the "Twin Bear." from 296ardun: Thanks, Dave... "VERY early Howard Cam Special, still running carburetors ... if I remember correctly, Glenn Ward was one of the first drivers of this car....before Jack Chrisman took the helm."
I keep hearing about the butterflies on an Enderle Bug Catcher are too large to work with electronic setups. I haven't looked in a while but BDS had a ready to buy electronic bug catcher a few years ago. I need to check with them to see if its still available. I am in hopes that myself or someone else figures out how to make it work. To me the finned bug catcher is the only way to go. I have one waiting and it looks so good to me even if it just sits there in the shop.
What's the round snout on the Potvin piece? Pop-off valve? Never seen a Potvin on a Hemi, got more pics? Do you have more pics of the Howard chain drive? thx!
Boy, on that second one you have a LOT of load on that crankshaft snout . . . given how far the blower pulley is away from the block. That would worry the Hell out of me. Is the crank cast or forged?
That helps, but you might consider making a "snout support" like we do on competition engines - even when we have big billet cranks in things like BBCs and Hemis. But you may not have the belt very tight, and the blower is probably not stripped . . . so maybe the load is very low. Just thinking out loud here! Not trying to be an alarmist.
