    you could leave what you have and replace the rubber biscuit with a 55 to 57 chevy type which would raise you to where you want to be thats what i did problem solved

    looks low..you might have steering box clearance issues with the side of the block
     
  3. If you do decide to raise it a little, why not just make your own copy of the Hurst mount
    with the added height built in. That way your frame mounts could stay the way they
    are instead of looking like "towers".

    If you want to raise the engine, you better check the bell housing/transmission, and driveshaft, verses the floor issue. Move it up for better fan placement, and you might be putting a big hump in your floor!

    It looks a little low to me, but i like putting motors in high.

    you might run into lower hose/fan clearance issues too.

    Alot of the hurst motor mounts ive had had the U shaped spaces that came with them, so it would raise the motor like an 1" or 1-1/4" which would help a little.

    the other pic is of a friends 31 roadster, that has the u shaped spaces and also "jeep" or trans dapt motor mounts in it, they also made it so the mechanical fuel pumps would clear, we made the frame mounts out of some 2" wide 1/4" thick flatbar and bent them on my press now this roadsters is very low slung so we put the motor in a little higher yet again.

    How are the mounts upside down when I made the mounts to go that way? I purposly made it low to have a flat floor as I said in my post. Very cool truck keep us posted on how you did it.

  12. If I am not mistaken the hurst mount makes it impossible to use a mechanical fuel pump. And Speedway motors makes a "hurst" style mount for $49.95. Hope this helps a little.
     
  13. Because you copied a Chassis Engineering/Tardell style piece that is designed to go the other way:rolleyes: Everyone that knows these will look at yours and wonder why you welded them in upside down?
     
  14. I think it's just about right. Here's mine when I mocked it up and then the finished product. The advantage of sitting lower is it will lower the center of gravity and handle a bit better. Mine goes in and out of corners very nice and I have a flat floor and I think it looks good the way it sits. I ran a mechanical fan with a shroud at first but have switched to 15 inch electric now.

    I haveint read it all but i thake two longer bolts on the crank and use a tube like 1"by1" and put that on the frame straight over to the ather frame rail and the bolts on the crank rest on that, then it will be right in my mind, you can puch the engine forward and back on the frame so you can get the right clerense for the radiator, a to low engine is mot good for the cooling, the fan comes to low for the radiator, there are raisers for the water pump to get it better, but build it haiger and you get the fan rigjt and the lower vater house right for the inlet on the radiator.
    So there are many good thing in a not to low engine.

    Sorry bad english

    ELpolacko, thats some nice work man thanks for the pics. could you tell me where the crank centerline is in relation to the top-center of the front crossmember?
     
  19. The crank center is level with the top of the frame rail.

    the frame rail or the crossmember? crank center looks lower than frame rail in pic. hard to tell.

  21. The crank center is level with the top of the frame rail, just as I said.

    This is a 32, but for instructional purposes it's the same difference. Pictures of the engine mocked up and before I built the mount.

    Nothing wrong with mounting it low. I kept this one as low as possible to minimize the transmission intrusion into the passenger compartment.

    Trad 27 has it right.
    Use the crank center as the Original A had it. Problem solved

    It looks pretty low to me. Sorta like Scrap Metal, I put the engine in the chassis with the pump and fan installed. Install the radiator. I use a stock fan, position it with one blade straight down then raise the engine until the tip of the bottom blade is even with the bottom of the radiator core - so the whole fan is facing the radiator. Make it about 3/4" back from the radiator core then I build mounts in a style to match the period I'm going for (usually late '50s to early '60s). My last SBC/Model A had Tardel style mounts that were 1" above the frame surface and custom engine mounts using early Ford biscuits. The hump in the floor was a whopping 1". You don't have side mounts so you only have one option and that's to make/modify the Hurst style front mount. El Polacko's is super nice.
    I don't remember what trans you are using but remember, if you're using a rear mount and an aluminum bellhousing you should make some kind of mid mount like '55-'57 Chevy's have to reduce stresses on the bellhousing.
