    I have the following frame mounts in my 1970 Camaro, but the SBC will not bolt in. I bought this car without an engine, and these were in the car. Left Side 3964890, Right Side 3980930. Could anyone tell me what these mounts are for, and if I can use them to install a SBC? Thanks for your assistance.

    demolitionman13,

    You have the correct frame mounts for a small block V8 in a 1970 chassis, the only other mounts offered in 1970 were for the Z/28 and L78 cars which were about 3/8" lower. Your small block should drop right in with the proper engine mounts on the block.

    Thanks for the reply. The engine side mounts I have are just alike, and 1 has Part Number 2267 on it. I am installing a 400 and I bought 1 new engine side mount for a 350 car and it is just like one I already had. Does the 400 make a difference? The engine falls right into place on the passenger side, but it is about 1 inch away from the hole on the driver side and I can't get it to line up.

    Your enging being a 400 should not matter, externally it is the same as a 307, 350 etc. I can give you the original part # for the engine mount you need, maybe your local parts store can cross reference the number.

    1970 Chevrolet parts book lists the mount as

    Nova, Camaro (307,350) (exc. Sp. H/per.) ....3964895

    Hope this helps....Alex Martindale

    I am not sure how far off your mounts are but the Second Gen Front Frames
    Sections have a tendency to sag. I have had to spread more then one to
    to get the engine bolts to line up. You can tie the side rails down and lift the
    Center of the frame or just put a Porta Power Ram between the Control Arm
    mounts

    Is there any way I can measure to see if the frame is sagged? I tried it again today, and I am about 1/2 to 3/4 of an inch away from getting the engine to bolt up, and it seems like the engine is sitting really high. When it is "almost" bolted in.

    One way to tell is if you have any alignment shims in the upper control arms. If only a few or none it needs to be spread. When I spread them I go over a little because it will settle about 1/2-1 degree on camber and also enough to put some shims back into it for camber adjustment and to bring the caster to at least 2 positive. This should also line the mounts back up where they need to be...

    There's also 2 different engine mounts which bolt to the side of the block, a short style and a tall style. This may be what you're trying to fight as well. I believe the tall mounts go on the short brackets, so you'd need the short engine mounts.
