Hi Gang, Last week I dropped off a spare 58-62 Chevy 235 at a machine shop to have it gone through and replace anything needed. Once it returns we plan on replacing the existing 235 in my 52 Styline Deluxe. I'm planning on swapping as many of the upgraded parts off the existing engine onto the rebuilt engine. I understand that the Carter Weber carbs and manifold will fit along with the Fenton split manifold, and the HEI distributor? Question comes with the water pump, I know I will need a short shaft water pump? I've heard that I will also need an adapter plate to center the water pump? Also I read that I will need a front motor mount? Your guys that have made this swap will know. I'm not sure of what I will need. The current engine I will be replacing is a 54-58. Any help you can give me will be greatly appreciated.

Ralph

Hi Ralph, sounds like you have a handle on it. It depends on what was done last time. Does your car have tower mounts? (52 on.) If so the triangular bolt pattern on the later blocks is different.

The three bolt pattern is turned upside down and aligned differently. There are old posts on this including aftermarket brackets and how to rework original mounts to look factory.

If you have front cover mounts this isn't an issue. But you will need to drill the new front cover to match.

What is your existing water pump like?

Cheers Kiwi

Hi, thanks for the reply, for what I've been able to come up with is it will require a front motor mount, unless I'm able to adapt a side mount. I should have paid a little more attention to bolt patters of the side of the motor. With the engine at the machine shop out of town, I'll just have to wait until it returns to know exactly what I need. As for the water pump, I plan on buying a new one, so I will have less to worry about when on the road. Do you have any recommendations on where to buy a new water pump. I ordered one from Patrick's last year that I never got, which will go under lessons learned.

Hi Ralph. Ray and I had a long post on this a year or so ago. Lot's of pictures etc.
Not only 261 but later 235 also.
Aftermarket brackets exist but they have those shite SV Ford biscuit mounts.

I live in paradise so can't advise on US suppliers.

I seem to have misplaced the numbers off the block and the engine is out of town. I know we looked up the numbers and it was to be a 58 to 62. Fortunately I found a paper that was on overhauling a 59, 235 with some pictures. It references the adapter plate and the front motor mount. I'll look for the numbers in the mess I keep in my desk.

I am going to look at a 62 engine. I my car has the side mounts to accommodate th 54 motor. I am reading here that if I install the 62 motor I will still need to get motor mounts for the 62 motor. Is this correct?

Will the 62 motor bolt up to my 54 powerglide?

Thanks, Pete

Thanks for the reply, I will try to find your post and maybe it will clear up some of my questions? I found a couple of places that sell the adapter plate and the short nose water pump. I need to call them to make sure they really have them.
Thanks

Ralph

The motor currently in the car is a 56. 235. I know the motor mounts will have to change.

You will need to make adapters for the motor mounts or buy these from Davis. They are used with the existing 52-54 mounts.

Link to Davis adapters

Thanks for the pictures. My Fenton headers would possibly hit, using the tower mounts. My current mounts are are on the side of the engine. Thanks for the link, I'll add them to list of others I might need.
Thanks

Ralph

Hi Airlifter. The later side-mount 3 bolt block pattern is not the same as the early (Up to 54) tower side mount bolt pattern.

As a triangular pattern, it is both upside down and possibly a different shape. There are aftermarket adapters and also I have posted images in the past of a Hamber who reworked the bottom half of the tower engine bracket to make a super stealth change.

I also recall that either Robert or Butch, as well as others, have made their own, and posted dimensions.

Not sure on late Powerglides as we didn't get many Downunder and they had the removable bell with the GMH bolt pattern to fit Holden engines, not Chevy. I can't recall hearing that the Engines don't bolt up if you have all the 54 pieces.

Cheers Kiwi
