    I'll second the concern about the sweat copper sleeve. Make one out of steel.

    Very cool! You have any pics? I have yet to determine how the oil level should be indicated on the dip stick. And I'm waiting on the heads so's I can locate the top of the dip stick tube.

    Well shit!!!! Guess I gotta re-do that pickup tube. Thanks guys for your "heads up". Better have egg on my face now than being stranded on the road.;)
     
  4. MrBill, In my estimation, having to change that one small item isn't a mistake, it is just an improvement. I also shivered when I saw the copper, and feel better that you are changing to steel.
    I have always admired hemis, but have never worked on one. I have thoroughly enjoyed watching your build.

    Following and enjoying your thread. Any mention of "Poly" gets my attention with two 318 Polys in my hot rods.
    Any details on the engine/trans combo in your 32 roadster?

    Thanks for that info Bill and being a Mopar fan I'm real happy that you tossed an SBC for a Mopar Poly/Hemi. What cars ran the 315 Poly and 325 Hemi?

    Thanks for that George, my lack of knowledge is because we never got those US models here in Australia. Chrysler Australia concocted a Chrysler Royal with the flat six then in later years added the Canadian 313 Poly.

    Here Dodge had only the 318, Plymouth jumped from 301/303(?) to 318, no 313.

    The '56 500 could be had with the 315 Hemi. The '57 models also came with the 325 Poly as did the '57 DeSoto Firesweep

    Yeop.
    Makes the exhaust pulsations equal, each collector gets 180° pulsations just like a flat plane 4 cylinder.
    The typical American V8 exhaust burble is the sound of inefficiency. Equal pulsations mean more power and the collector doesn't have to be massive along with exhaust piping can be a smaller diameter to save weight as well. Get to keep the well balanced cross-plane crank in your engine and not have to worry about 2nd order vibration shenanigans that require balance shafts on larger displacements.

    Bought the car in 2004, had a SBC and manual trans. Proceeded to make it my own, over 16 years via wheels/tires, lights, paint, extended cockpit, top, cowl steering, Hemi, headers and a 5 spd. Learned how to do it all on this car. I love this car!
    Here it s today with 325 Hemi, S10-T5, 130K miles in U.S. and Canada.

    Thanks for that Bill, you have definitely succeeded in building an excellent hot rod. It has a great profile and I like to see rods using the not-so-common engines in the Rocket, Nailhead, Cadillac plus the Hemi and Poly as it makes the build so much more challenging (and expensive)
    Your roadster is just so right as it's on the road being used and enjoyed as evidenced by your 130k miles in the last 15 years.

    Thought I'd throw this out just for grins. Seen at the Long Beach Swap Meet last weekend.
    Check the throttle linkage.

    And, I have been futzin with small stuff just to make some kinda progress while I wait for the cool components I'd rather be working on. Body work on valve covers and the pan is no fun. Hopefully within the next week or so I'll have heads, a cam and rocker arms to bolt together.

    Have to do some nibbling on four breathers so's they fit in the groove.
