    The dash and header both look great!!
    If you don't mind sharing, what steps did you go through to weld/grind/finish the header tubes so nicely?

    align the two tubes using whatever means you have
    fitment of course has to be near perfect

    tack with mig
    weld with tig
    carefully grind down weld to very near parent metal
    hand file to flush
    medium grit paper disc on 4" grinder to clean the file marks
    DA with medium grit, I think I used 180?
    and finally hand sand to take those marks out

    it actually goes faster than it sounds
    again biggest part is getting the pieces to fit nice to begin with

    I'll try to take more pictures on the second set

    thanks, looks like you have pretty cool car yourself

    I very nearly went with a 4-71 blown small block in mine too
    but when the parts came together to put an Olds in it I had no choice

    on to the second side,

    clamped a short length of small channel in the vice
    layed two pieces to be joined in it and tacked them together in three places

    welded each tube up

    [​IMG]

    grind and file

    hit them with the little disc sander

    'going to make some block off plates and outlet drops to run the exhaust under the car, through mufflers out the back... I think :)

    Paul, Your "A" is going to be one mean "A" Coupe ! I have a '31 "A" Coupe with a '57 Ford Marine Y-Block. It is adapted to a '46 Ford truck trans and the rear is a '41 Ford car. Car is mostly figured out but needs finishing. Will be building a stand alone water pump for cooling. Hope my "A" is 1/2 as cool as yours.

    sounds pretty cool to me,
    makes me think of the pink? one Marshall built a little while ago
    I really like the way the Y blocks look
    somebody once said they go pretty good too;)
     
  16. Paul,,,Beautiful work and attention to detail! HRP

    welded the primaries to the starter tubes,

    pinched the tubes together where they meet inside the collector
    welded them together and about an inch or so up the tubes

    [​IMG]


    tacked the collector in place to check alignment

    [​IMG]


    back to the bench to weld the collector on solid
    then bolt back on one last time

    [​IMG]

    that's as far as I'll take this side for now,
    stopped to take the turkey out of the oven
    start the cranberry sauce
    then it's back out to the shop to put the other collector on

    Paul, I am also building a '41 Fordor with a Y-Block. Hope to have it all dolled out with T-Bird valve covers and 3 carb intake. Hope to be able to make it a Kustom. Chopped 2 inches, sectioned 2 inches and channelled 2 inches. Just got to do some wheeling and dealing.

    Merry Christmas to you and your family.

    Dave:eek:

    I've only heard it on the test stand through mufflers
    and that was way too long ago

    I'm sure it will sound a bit different now

    The picture you posted of your pickup in one of the header picture threads, meaty beaty big and bouncy, was an inspiration


    Count on it.

    picked up the radiator from the shop yesterday
    I had them build it without brackets so I could not only save a few bucks but I wanted to make sure to get them so they fit the way I want them to.

    started on that today,
    bent up a strap to go under the bottom tank
    tacked the upper shell brackets in place
    and got a plan for the lower brackets.

    but I may need to modify the cross member to get the whole thing a bit lower..

    took the week between Christmas and New Years off,
    between chores I did manage to spend some time on the Coupe

    in an earlier mock-up I had tunneled a small block Chevy into the firewall,
    now that needed to be fixed.

    I found a crusty but solid donor firewall somewhere in the past

    [​IMG]

    figured it would be just as easy to patch the original as replace the whole thing
    so I did a rough layout of the patch needed

    [​IMG]


    and cut it with the trusty little grinder with cut off wheels

    [​IMG]

    clamped it behind the original and marked it for trimming

    [​IMG]

    and welded the lower half in,
    I intended to cut the center out for magneto clearance
    but left it in one piece to help with initial patch alignment

    [​IMG]

    when the sides were welded in solid enough I cut the center section out

    [​IMG]

    bent up a recess out of similar gauge steel

    [​IMG]

    tacked it in and trimmed it a bit

    [​IMG]

    pounded out a bit of a dome to fill the top of the recess

    [​IMG]

    and welded that in

    [​IMG]

    fit the remaining patches using new steel

    [​IMG]

    worked it into shape with hammer and dolly
    and stripped the paint and rust

    [​IMG]

    while the tank was off I cut the top free

    [​IMG]

    and set the body back on the chassis

    the engine just clears the remaining firewall,
    plenty of room for the plug wires
    and just enough room to pull the magneto

    [​IMG]

    [​IMG]

    slowly coming together

    [​IMG]

    that's all for now folks!
