    E9C42648-EC9F-4B39-8573-EFC804C657A8.jpeg Went for a spin yesterday after work. Need to lean it out a little but starts and runs good with the burns/97's combo. One carb had 45's in it, the other 52's(!) A lot quieter with stock exhaust but that's ok. It'll get a straight pipe after I get the timing nailed down.

    Yes it is...I'm kind of thinking that it might become the popular one

    Bit of an update on the A motor I’m rebuilding.
    I’m changing the ports on the F head from side draft to semi downdraft. The reason is that the ports were so flat that the flow was below 50%. The 1-7/8” valve was flowing less than a 1-1/4” valve in a 1960's pre Crossflow engine.
    The head is a two part jobbie so a bit easier to work on. First bit was to weld up the existing ports. For this I filled the void with weld rather than make shaped pieces and weld in. The idea was that when I start the porting I don’t want to be limited, ie not going through the welds and exposing cracks.

    E9F90094-A438-4F56-8CB3-5AA9B7991131.jpeg 104FCDD2-26B0-4044-81F4-8EA87636453E.jpeg 49866218-E3FE-4FA6-ABEC-E54DA2F17757.jpeg C311F2AF-7340-4F0C-9AA9-C54D223D245E.jpeg

    The top part of the head I welded four tube parts at a 40* angle. This will be the new port angle. And like the first part was fully welded. Total Welding time was 20 hours.

    15889677-4C27-4CFE-9A55-D20C96147409.jpeg 97F45BF3-7143-46FA-A5AB-0F4435878CD3.jpeg EB649037-707C-4817-BD78-AB3267009E35.jpeg

    A plate was welded on as a mounting flange for the intake manifold. I also couldn’t stand the hard corner billet look so attacked it with a sander to give it some shape.

    6863179E-9647-47F5-A62F-8FCC9D5065A8.jpeg C8AA933B-3C8E-4AA2-AF80-2965CA843BFF.jpeg

    Using a friends mill the head was set up on the table and a 35mm hole bored through. Ignore the slight scar, the end mill jumped out and skipped along the face because I didn’t bolt the mill head up tight enough. It welded up fine.

    05B936E7-F2DF-4CA4-8328-505B420C5209.jpeg 0F75DC24-8D7A-484E-A2EA-101177E85D0A.jpeg C24F348F-97F7-46C3-8304-B0BF7B29975C.jpeg ED0C989A-DAE3-4542-96F1-B9182A1698A7.jpeg

    Still with only 35mm bore I finished up the ends of the port by hand. Just to see where we were and in the right place. The head will go back in the mill and eventually be opened up to 45mm.

    1B169963-5C7A-417D-8664-48F45F472CFC.jpeg D337C6BB-4CFA-445C-9F16-B9F698BFA7FE.jpeg D0B6ACCB-0E1A-40F0-B1D8-8612DC9FEC26.jpeg

    I’m also working on the bottom end. The front and rear main caps were already fitted to the motor by the original builder as was a similar centre cap. I’ve made a new centre cap wider so it can be bolted to a couple of plates to tie the block together and strengthen the centre bearing.

    WOW !! I like your interpretation of the Riley chambers also.
    Amazing talent. Let's see the 'drawing'..lol

    BTW Pete:
    I have an original alum Cragar intake (single) that would benefit from a guy with your skills/talents. A lot of these old intakes had an 'ear' broken off, as in this case.
    I'd give you this intake, if interested, so that you can perform your creative magic on it ! PM me if this interests you.

    aww hell I have to go on a rant...one of the rem offys had a 727 chrysler automatic behind it..I know a brother took a lot of time, money and effort making that car,and it ran well..but from the cheap seats it ran looked and sounded like a Pinto..

    Yeah, the 727 is the auto used by the old timers, as they fit the bill well for use with a banger.
    Old timers, who I know that use this auto, are not in the best of conditions. Did you happen to notice the age or physical condition of the owner ?
    One day, maybe sooner than later, I will be grateful to have a 727, if I can find someone who can install it.

    How does it run under load?.Run her some,let it break in real good before trying to achieve a good tune.

    The yellow car is Dan Shanahan's out of the wine country, was with him Tuesday, hoping that we will get together Friday for our informal cocktail session at the cam grinders.

    Runs great under load. No hesitation or flat spots. That’s why I’m so hesitant to fudge around with the tune, but that little “burping” is annoying me.

    That's pretty cool.I did a lot of cutting on mine but still ended up around 43lbs.Not sure were it would have been safe to remove more without reducing wall sections.Do these bangers need some weight to offset some balance issues or is that just a myth ?

    @burl I've heard that also. But from what I've gathered is the weight of the flywheel was to help lug the motor if you were stick in mud and was easier to get the motor going when hand cranking it. Are any of them true???

    While working on my '31 Coupe I've been kicking around the idea for another T roadster. One iteration would be a more "modern" approach, and the 2nd is quite traditional. For the traditional approach I'd dig out the Model A driveline that I didn't end up using in my '31 for various reasons that would be pointless to go into.

    In getting a Model A banger in shape I'd be facing either having mains and rods re-babbitted, or going to inserts on mains and possibly rods too. I'm hoping for a 55-60-ish HP banger in the end, so nothing wild at all. In considering the costs involved, it appears that it would be somewhat comparable to go either way, Babbitt or inserts. Most shops I've found that do re-babbitting are 5-6 hours or farther away from where I live in Southeast Missouri. I'm wondering if there's any reason that a local performance engine builder I know couldn't do the line boring necessary to do the insert conversion for the mains? It would save me a bunch of time and/or money in transporting parts to a rebuilder if the line boring is straightforward work and could be done locally.

    If I'm not mistaken Bert's has re-babbitted rods for about $60 each with no core charge, and that seems really reasonable compared to other pricing I've seen for either babbit or insert bearing rods while researching possibilities.

    Input is appreciated.

    Took my engine to Bert’s last fall for a look see. Picked it up a couple of weeks ago and fired it up yesterday. Went from a 3” pulley to the stock 5” and had problems finding a 44” fan belt. Everything is back together and runs great. Heading for Lincoln in June for the Speedster Reunion at Speedway Motors.
