    I know asking for opinions around here is like taking my life into my own hands, but I'm looking at options on setting the 350 into my Dubble A as I get back to working on it.

    Basically, I'm looking at 2 different options and am not sure which'd be the best way to go, so I thought I'd ask what you all think.

    Option 1: The tubular type universal crossmember that bolts to the inside of the frame, but you cut it to fit the width the frame itself. Like this one: http://www.speedwaymotors.com/p/327...er-Mounts.html?itemNo=crossmember motor mount

    Option 2: The Hurst style (I think) mount that attaches to the lower front portion of the motor and uses the puck style mounts/cushions where it attaches to the frame.
    Like this one: http://www.speedwaymotors.com/p/672...Motor-Mount.html?itemNo=universal motor mount

    Basically, I'm looking for opinions, as well as pros and cons to both setups.

    Thanks!

  2. I think you would be hard pressed to find a better looking setup than that Hurst mount.

    Buying the mounts may be easier but you could always make them yourself.
    We have used the Hurst with no problems but I'm sure the other one Speedway sells works fine also. You may want to see where each mount attaches to the chassis and see if it works with the rest of your setup.

    Here are some home made ones.

    The hurst style isn't really a full load bearing member of the frame due to the flex at the mounts. Style 1 actually reinforces the frame while mounting the engine.

    Shifty, that is kind of what I was thinking, but I'm open to different experiences and ideas.

    How much will that make a difference being that this thing is going into a Model AA (Dubble A) frame?

    The hurst type mount has the engine being held up by 4 bolts in shear plus you are normally unable to use a standard mechanical fuel pump.

    The cross member type mount allows the use of the furl pump the mounts bolt with 6 fasteners and the cross member adds to frame stiffening.

    YOU CAN'T VOTE FOR ANYTHING BUT THE 2 I POSTED! Sheesh.. like a bunch of my 6th graders!

    Seriously though, I'm more up about the 2 choices I posted rather than the other. Although I'm sure it has its advantages, I'm leaning more towards the crossmember type.

    You really need to determinne where your transmission mount is going to be when making this decision. Typically any motor with the front (Hurst) mount will (Should?) also have mounts at the bellhousing, and the rear of the transmission. If you use a front mount and a rear transmission mount with no "bellhousing" mount, you are putting undue stress on the bellhousing, particularly on an SBC where the bellhousing/motor are basically connected with a half-circle of bolts. The crossmember mount kind of "balances" the engine weight over it, and puts a lot less stress on the bellhousing. I vote for the crossmember mount because 1) Fewer mounting points required. 2) Doesn't block off the original fuel pump location 3) Stiffens the frame 4) is more "hidden"
