Projects The Hardscrabble Hop-Up; A 1940's Style 'T' RPU build

Discussion in 'Traditional Hot Rods' started by gwhite, Jul 21, 2013.

  1. Jamie, that's a very good question! I would guess this combination would be good for 65-70 horsepower and 155-165 ft-lb torque give or take. Dual carbs, a modern ignition system, and free-flowing exhaust would likely give another 5 hp/10-12 ft-lb.

    This is probably in line with the average "hot" late-30's to mid-40's 'banger. IMO, valve float is the limiting factor in most of these engines, and the primary reason the OHV conversions and larger displacement V8's could not, for the most part, outperform the 'hopped up' flathead 4's on the lakes. To combat this, I had steel valve spring spacers machined to increase spring pressure, which should reduce float. That said, my A motor will be limited to 3500-4000 RPM, as that's probably the practical limit to stock (styled) con rod fasteners, shimmed valve springs, and splash oiling. This corresponds (roughly) with a 90-95 mph top speed (with stock gearing and 30" diameter tires)....a good speed in the late 1930's - early 40's.

  2. Nice.....about twenty pounds per horsepower then....at least. Yep, that thing is gonna' fly. Thank you sir.
     
  3. It looks like you should be ready for Round Up if you'd quit typing and start working, just kidding. Keep at it!!!

    Looks great Gary. I am hoping you're going to post a video of the test fire!
     
  5. Probably not...still have more asphaltum paint to sniff, uh, err paint first :)

    Actually, I'm on a bit of a hiatus for a little while...broke my tailbone last week, so I'm learning the hard way that the phrase "butthurt" is a real and painful truism.

    Shoot neighbor, I may call you when the time comes to see if you want to accompany me :)

    See Gary, if you wouldn't have invested so heavily to get into the "90 mph" club, your pocketbook may have had the padding required to save you from injury.

  10. Honestly, it's not all it's "cracked" up to be, hahaha. Ouch. @3wLarry says I'm "anal" (no pun intended) about the details - I'm a little fanatic about keeping all my parts organized...to make a long story short, I was dragging a heavy container across the garage and lost my balance - caught a piece of angle iron right in the tail. Literally.

    Sorry about your ass break:rolleyes: I've broken mine several times. Not much you can do about it and it sucks to sit on it!
    I had to sit on mine on the train from RI to Jersey. Man that was a long ride! Hope your bum is feelin better soon:D

    BTW, you still want the panel? I'm not in any rush, just wondering.
     
  15. The result of sitting down on the job.

    And yes, I cringed reading about your fall. Heal quickly. Cracked tailbones are no fun at all. And you can't even get your friends and family to sign the cast.

    I missed your Updates, I came in about where your engine pics was.

    B) :D LOL.

    I've been sitting on that one for three pages, but still not as painfull as it must be for you!
    Get Well soon, and get cracking. :)

    Love this build. If you'd be interested is selling the pump/gauge bezel, I would be interested to use it with my pump and gauge.

    Your first set-up is similar (very very alike) to what I will be doing in a couple weeks.
     
  25. Sorry Brent, just saw this...shoot me a PM.
     
  26. Small update and a setback; motor is ready, got a quick test fire in, but couldn't run her very long...carb is spewing gas all over....need to tear it apart again.

    Will get video if I can get the carb dialed in well enough to actually run it for any length of time.
