    Jalopy racing is something I can do every weekend. Racing is racing no matter how fast you go. The Jolopys are great fun.
    I've raced other people's cars at Bonneville but having my own there is like a dream.
    Thank you!

    Sorry first time back on thread. An ez rubber mount to day is from Circle Track which are sort of wings bolted on the bellhousing bolts and use flathead Ford donuts. Since I see your building a race vehicle solid mounts are fine even with the 6. They have their own vibration problems which I fought for years even when going over 200 at Bonneville in our roadster.

    I went 136 at Loring and will be changing gears for Bonneville where the record is 131. Thanks for getting back to me.

    Thanks Jerry
    It's a 3/4 ton. The frame is a lot heavier than the hald ton.

  9. I've been intrigued by the 2 x 8 wood cylinder head on that old Jimmy six.

    Better combustion
    Or just a better.place to pile tools and bolts. Its a 270 we'll replace with the 302.

  11. Nice work, I didn't remember my frame horns on my Chevy dropping down so far but after further review I guess they do.

    I know a couple guys that've built some serious drag trucks out of these and roll bar fitment is always an issue. Here's one of the guy's and he just stepped this up to a funny car cage style.

    Seems like when you think you have a roll cage that should meet the SCTA rules by ready everything in the rulebook an inspector will find the need for at the need for 30-40 more feet of tubing. A Randy LaJoie seat may not even be enough for some.

    I ran my 311” GMC 6 many years ago at Bonneville in a stock body 40 Chevrolet coupe running boards and all at 141 so your 131 is very doable but the Ford 6 camp has been fighting gremlins/growing pains for a few years and he showed a hell of a lot more HP than I’ve ever had.
    The engine currently holds the XO gas roadster record at 169+ on one 4 barrel. Here’s a photo. Good luck I’ll be watching your progress along with many... 1BFC6651-9821-4D31-9A64-D04CA6AA5EA4.jpeg

    I've sent in pictures of the roll cage and i hope they will let me know if they don't like what they see.
    I've seen your records and admired your efforts. You probably know I've been to Bonneville several times. I ran a 302 GMC in a 57 Chevy at Loring and did 136 in the mile and a half. I'm not saying I'm going out to set a record, I know how fickle the salt can be, but we'll give it our best shot.

    The truck has arrived in PA to join the Flying Seven team. Going to start cleaning up the cab and get some painting done. IMG_20201206_143930774_HDR.jpeg

    Putting a nice thick coat of Rust-oleum on the frame with a brush. Anyone else do this? IMG_20210103_160610657_HDR.jpeg

    Sorry haven’t been following. It a early 600 with vacuun secondaries. Built and modified 30 years ago I’ve just stuck with it... tried others but always come back to it because it fits under the hood. In our 40 Chevrolet we ran a Clifford Research 3-2’s tubing manifold with 3 Holley 280 cfm carbs that were stock on 1960 Mercury’s. Tubes were 10” I’ll take a photo and post it.

    Frank out the bump stops on the front and back. The master cylinder is in the original location. A lot of engineering went into that, rather than hang it on the firewall. IMG_20210109_150740693.jpeg IMG_20210109_162610012_HDR.jpeg

    Got a big order from Jim Carter today. Mostly bed parts. Can't wait to get started. They look like well made parts. IMG_20210114_131259013_HDR.jpeg IMG_20210114_131739797_HDR.jpeg

    Marcia, thanks for posting the picture of your brake M/cyl. I've been wondering how I was going to fit a brake cyl and booster along side a T5 and keep the m/cyl in front of the seat for access to the filler. Duh, turn em around! Sometimes the simplest solution is the most elegant.

    The original floor fits in with little modification.
    Again we're working in the truck daily. As you know, these projects go slowly.
