Technical ***October 2022 Banger Meet Thread - Happy All Hallows Eve**

Discussion in 'Traditional Hot Rods' started by Jiminy, Oct 1, 2022.

  1. IMHO, it was too much potential HP from a too small crank journal
    Please understand this is not CDO’s broken crank
    This from a jubilant delinquent elder but still pushing close to 200 hp
    I feel the “A” journal is too small and then drilling hole thru it reduces the area of material causing stress risers
    The solution as I see it to put a “C” crank in the “A” block without compromising the crank (not grinding to “A” dimension)

    Aren't the SCAT cranks cast and not forged?
     
  3. Folklore, mainly,
    Those SCAT cranks are forged off shore and finished here.
    Of course you can find custom SCAT billet cranks too, not broken usually.
    There have in the past been cast cranks, Dan Eubanks had a "C" cast crank and Bruce Johnson had cast steel cranks.
    I am sure that more have been made over the years, you eventually find them if you stay playing with this stuff.

    Found a set of wheels plus two heads and an intake at Hershey.
    Didn’t find the Winfield carb I was looking for, but got a couple contacts who might have some stashed away at home.

    He told me he was looking for someone to make them. I already have the Cyclone so I don’t know how much I need to have a Brierley.

  9. Oh you need one, or two more...
    The tooling is at the foundry, it will be awhile.

    I’m sure I won’t pass one up. I hope to build a second engine but I first need to pull the engine in my truck and get going on the first one

    Probably not as good as a cam ground for a flathead.

    What do you recommend?
     
  13. I like my Brierley head. Needs far less advance than the Thomas or Winfield I previously ran. Very torquey and economical too! Tried to get another but Jim said Edelbrocks had returned his patterns as they weren't doing any more sub-contract work so he was trying to find another foundry. Good news if he has. Bad news is the sterling exchange rate is so bad I can't afford it...

    Depending on what mods you have done on your engine, the following 3 cams work very well.
    I am running the 1R in my coupe with stock valves, 6:1 head, single Stromberg 48 carb, and a header.
    I'm running the M-28T in my T RPU with a B engine that has 1.7" intake valves, 7.5:1 head, 2 Stromberg 97 carbs, FSI ignition, lakes type header.
    I have never used the 1A cam.
    I like the M-28T because it breaths better after 2500 rpm. I think in this engine that the 1A would be better.

    DIRECT ACTING (FLATHEAD) CAMS

    No. / duration / lift / int. / exh. (Clearances)
    1R / 266 / .350 / 010 / 012 180* @ .050”4 Winfield grind

    M-28 T / 280 / .355/ 012 / 014 214* @ .050” Fair Idle good street

    1A / 285 / .362 / 010 / 012 190* @ .050” Winfield grind - good

  15. Yes,
    since Edelbrock was sold the sub contractor work stopped.
    I think he visited the foundry making OHV and girdle castings, will get update tomorrow.

    I can relate, you have Sterline exchange rate, we have gas, but I think is comparable to you now.

  16. No tinkering right now, but I did get my new run of finned cam covers back from the foundry! 979951AA-7FF9-4323-82B8-D5C1A3F8F301.png

  17. Checking in, it’s been a while. All these photos of heads reminded me of a decision I have to make on a motor that I need to build. The stock model A pistons extend above the block, does anyone know the logic/engineering reason Henry did this? Was this to try and protect the head gasket from the full force of the ignition of the mixture? On a new build would it be better to have the pistons flush with the block? Would this create problems with swapping heads, because of loss of compression. I know some heads have no relief for the pistons ( Brierley heads ). Thanks in advance for any advice/answers
     
  18. I have a relief cut in all my heads, including the Brierley.

    Just for reference. I believe neither of these have been modified and are both new 42B67116-B71D-4915-A91C-08AD46D35C2E.jpeg 79B87286-F0A5-4A6C-94F3-98EFF751DCA4.jpeg

    Tearing apart my free stuck banger.... .110 over motor, seems ok other than being stuck... pulled the front main, gritty nasty, so just tinkering with it to see if the rest are that bad, It now rocks 1/2" so were down to stuck pistons... The soaking is continuing...

    banger1.jpg
    My 2 bangers, the red one is out of the 30, blown bearings.

    The A coupe, havent driven it much other than a few weeks ago to a AACA social
    seems after swapping carb bases out, I got my slight rich problem gone, Now the exhaust valves are almost white and plugs clean... Cant complain...

    Here is a few mile stretch of a backroad in the burbs, its only pretty like this for these few miles so I take what I can get.....
    COUPE 111.jpg

    Then here is a partial pic of the AACA social... My coupe makes the A club boys kinda pissy.... But I got a good idea of how much faster this thing is than a stocker, and damn... No contest....

    Not having played with different cam shafts to see the different out comes, I have been wondering how 'transferable' these profiles would be to different side-valve engines... ie. Does a hot v8 sidey cam profile work well in a Banger? (Given the carb/exhaust header improvement are also done) this is a rookie question & I hope this makes sense...
    The background to this question is that I am considering using another period flat head 4 in a project, there is very little performance work done on these engines & just thinking about a starting point.
    thanks,
    Glenn

    Out here fall motoring in Maine, putting off tearing the motor apart until the snow flies.

    Best I can tell you, the v8 grinds, made for more upper rpm running and power, like my 3/4 stipe cam, its choppy and you know its there, but the upper end of it really shines, I could only imagine what a burtz block with 5 mains and a great balance job, and OHV conversion it would sing I bet at 4500....

    Does anyone have the directions to FAB the throttle Pivot Arm that is used with aftermarket manifolds. I have the Riley Downdraft aka Equalizer.

    Used to be a PDF floating out there.
    Thanks

    Checking in! thrashed away on the car for most of September in preparation for Trog. Broke rear end testing it a week before so thrashed again finding a new rear end and getting it fitted the evening before I left.

    unfortunately the hurricane arrived before I threw any sand and I broke a key in the new to me rear end pulling out of our hotel parking lot…

    Now I actually have the time I can get it sorted! That’s what happens when you throw an unknown complete rear end in the night before.
