    Finally got the linkage working on the 32/36 Weber on my engine. Had to mill 3/8" off the ports and a 1/2" on the carb base to be able to get the hood on. Off to SoCal for three weeks. Will finish it in November.

    Like the can says, "chock full o' nuts" we are.
  9. Every year something comes up that keeps me from going. Will at least get there for Thursday this year. Expect it to be a monsoon to keep me from going.

    I thought in ca. , it was fruits & nutz
  11. What are the identifying marks/features between an A camshaft and a B unit?
  12. I'm back at the drawing board!!!! Just when I had her tuned and ready for a hill climb Race!:mad:[​IMG] [​IMG]
  13. Any word on a warranty?
    Did you go to spectate?

    Brett, easiest way to tell is to look for the fuel pump concentric. B cam has it, A does not.
  15. I chose to stay and pull the crankshaft instead. (That's Hot Rodding!?) I needed to get it out to send back to Scat. If covered it'll take 8 weeks! I'm trying to get the next one to be a stock stroke with B journals!
    I'm thinking they will cover it. I sure hope they do! It cost over 1,900. It was a custom made stroker.
    Thinking on upgrading to a billet 5 main,?
    Now I don't get to work on my 34 coupe cause the Roadster is in the middle of my shop!
    I don't like cutting and grinding while building an engine!
    So I'll sit and wait, while drowning in a pool of boredom!!!!

    bummer on the crank .
  17. Yeah V4F, It sure is a BUMMER!
    I wasn't thinking it could be the weakest link in my drive train, being that I'm running an original Model A ring, pinion and axles with woodruff keys!
    I wish it would've lasted long enough to race the hill climb last weekend. Sure would've made for a better story!

    Don't forget, if you go back to 4.25 stroke, the CH of pistons may not be right.

    BTW, this is not the first to go.

    Ok so after lots and lots of stalking on the net I have come to the conclusion that this chassis was built by @Justin B. I've sent him a PM regarding details with no reply. Does anyone know him, I'm sure he's a busy guy, but learning a few details would be great.
    Here it is when he had it
    as I bought it


    and how it sits now awaiting stuff to sell to fund the project
    The guy I bought it from knew less than nothing about it. It's a pretty powerful motor and will spin the tires too!! I'm looking for details, motor, rear end, etc...
    Please help

  21. Thanks John,
    I did hear about them breaking on no. 4 journal after the purchase. :(
    I also already have a new set of custom made Crower rods and Ross pistons for a stock C/B crank that was made for this block's bore and deck height.
    But If I go 5 main, Then I'll be looking for a good B block.
    I don't want to use this good block that already has a perfect align bore with billet main caps.

  22. Wow Tiny,
    I forgot how awesome that project of yours is!
    After I get my car back together, I'll come up and finally get to meet you in person.
    Remember, my crankshaft broke while I was on my way to meet with you and friends to go on a Model A reliability run?!
    Hopefully I'll have her back on the road in less than two weeks!
    Iv'e decided to run one of my already drilled C cranks!:D
    I'll be balancing my new rods and pistons first thing in the morning.
    I have no idea why they come in all different weights brand new?!

    Joe that is where I have broken a few in the past No 4
    How hard have you been revving it and what hp are you putting through it
    I ask because also run a scat crank that see s lots of rpm has lots of 1/4 mile passes as well plenty of highway miles
    On a side note I have not broken a crank since I started fitting balancers to the front of the cranks

    Brett, for what it's worth, this is a "B" cam with a winfield grind.

  26. Can I take the whole starter drive off an A and use it on a B starter? When I first got my B we tried to use parts off an A and it didn't work but I think that was the Armature.
  27. Hi, I'm not sure of HP. It seems to pull hard! I didn't drive to hard or rev it out YET!. Iv'e only cruised it on freeway at 70 mph about 2,700 rpm..
    Maybe I do need a harmonic balancer!?

  28. I think it was just a bad crankshaft to start with!
  29. Hey Colin, do you have a picture of the balancer? I'm not sure if I have room for one.
    I can't even get my belt between my undersized pulley without either lifting the front engine mount or removing the u bolts that hold my axle spring on the front cross member.

    Harmonic balancer install sounds like a great Tech Week item (yeah, perhaps done to death but maybe a new angle?)
