1958 235 in a 50 Chevy. What about the motor mounts?

    OK ya'll I am encountering some things I hadn't thought about. The block I have overhauled for the Fleetline is a '58. The 216 that came out had the front mount plate. This block is a side mount. The plate on the front of the engine I have has no holes or provisions for motor mounts.

    Should I have installed the 50 plate first? If so it's too late the timing cover is on etc.

    Dang it....I should have caught this.

    Root, Drill holes in the 58 plate to match the 216 plate & you're good to go. I've done this before with no problems. Your 58 plate should have a lip to allow you to do this .

    I also have the truck front mounts that bolt onto the side of the block. Can I use them?

    We side mounted my dad's, it's a pain in the ass!
    It really limited the space for the dual exhaust on the driver's side.

    Root, offhand I don't remember what the '58 truck mounts look like...but it is very crowded on the driver's side with the way the stock steering arm moves through it's arc.. what bellhousing are you using? The only mounts I have on mine are the '49 - '51 style front mounts (just drilled the plate like the 216), and the side mounts on the bellhousing (as detailed in my little paper)...has worked fine for the last 50k or so.

    What I have is the L shaped brackets with the biscuit styled rubbers. Shoot I haven't tried to stab it yet...they may line up?

    I have a 58 bellhousing and a 58 model 235. Anyone have pics they could post?

    I think you will save yourself a lot of trouble by just drilling the plate in front and making it a front-mounted engine, plus it will free up space on the side of the engine.

    Here's how we did the old man's 51, we side mounted his 261.
    Driver's side.

    So is that the side mount on mine? Mine looks farther forward.

    Root,
    I'm running a '58 vintage 235 in my '54.
    I just drilled the front plate for the two bolts and used the front mount. It's the simplest and easiest way to solve the problem. I also built a front mount for the 250-six.

    They are farther back, the 261 has some extra mounting pads cast in the block.

    Hey Root, I checked my 51 Chevy yesterday & yes that's the same front plate I have on my 235, with holes drilled into the horizontal surface to match the stock 51 frame mounts. just mark the center of the frame mounts, set the motor in, mark the plate, drill the holes & you're done. This way frees up space on the side of the block to run your exhaust & it's quick & easy. Don't forget to use the side motor mounts off the bellhousing. OK.

    I'm gonna run into the same problem with my '49, I've got a 57 235 I'm going to put in. Where can I get the front mount plates?

    i just got done doing this in my 50. i put a 60 biscayne motor in... u have to use the 216 timming cover backing plate thing. u have to pull the cam out to do the swap. its real easy. and another problem your going to run into is the waterpump. mine took a few tries to get the right parts to work together. i used a 235 pump. mid 80's 2.5 s-10 water pump flange. then pressed that on untill the cheepy pep boys sbc (short waterpump) pully had just enough room to clear the cast of the pump (about 1/4 inch) this lined up my pullys perfect. i have a brand new pump and xtra flanges if any one would like me to build them one. o yea for a fan i used a late 70's ford fan from who knows what but it looks real close to stock 235 fan.

    You don't need to swap the front mount plates, just drill two holes for the bolts.
    That's it, nothing more, that's all.
    You can use the later water pump but you need to use the 216 fan to clear the harmonic balancer.
    Or you can use the early 235 water pump (same as the 216) and an adapter plate for the later 235 motor. Jim Carter's has the plate.
