I have a line on a 235 engine to replace the bad one in my 54 Chevy. I'm not sure of the year of this one. I know that the 235
came in later cars and from what I understand will not fit for some reason into 54 in earlier cars. Can someone give me an idea of the differences and what I would need to make a later engine work? Thanks!

Should fit, however issue may be motor mounts, depending on year of motor. In 52 Chevy went to side motor mounts. Earlier models mounted in the front on the timing cover. I'm not sure mounts on 52 and following years were the same thru the end of the 235 run, that's why I mentioned possible issue. The fix can be simple, by upgrading and or replacing mounts. Davis speed equipment makes a replacement mount that is well engineered.

The bolt pattern on your side mounts is unique to 52-54. Fortunately, aftermarket brackets are now available which will allow any 55-62 engine to be mounted in these cars. Note that all 55-up engines will require a "short" water pump swap in order for the fan to clear the radiator on 54-earlier cars. These pumps are available from the vintage specialty parts vendors. Note also that 55-57 requires different mounting brackets from 58-62. Both types of mounts are shown in the following links.

If you have any trouble telling the difference, feel free to ask for additional info.

My '56 Block is Front Mounted, so the previous owner must have used the original Front Mount Plate, on my '49.

Yes, it is much easier to install a later engine in a 51-earlier car than a 52-54 because you can re-use the stock 51-earlier bellhousing mounts and front end plate mounts. There is no need to buy or fab any custom parts.

$159 for those aftermarket adapters? Damm. Pricey little things. Make your own!

Hi Robert, there are some old posts on this. From memory complete home made, plus the old tops modified to new bases which is fiddly but looks factory.

Kiwi, rrausch made a set of brackets to install a 58-62 engine in a (I think) 53 car and posted pics of them on here. This was before the Davis brackets were available.

Hi Ray, yes I remember Robert's folded plate mounts. Plus there were the HAMB ones that had the old 235 factory 52-4 tops modified with reworked bases. Given the left and right are not mirror patterns it makes them time consuming.
