B from 113 to 135 ci

Morris Krodle · May 27, 2012

I"m going to try to convert my 113 to 135, was told that this could be done. Does anyone know the dimensions that have to be bored for the 135 sleeves to fit? Also, will the rods from the 113 work on the 135 pistons? Any other info would be appreciated.

If the engine is original it can be converted to 123 inches by using thinner sleeves. To be 135 cu in it has to be bored, the later Super A and Super C could be converted to 135 without boring. To do that without boring your block number must be 354894, if original it will not be that number. Simpler to go to 123, every thing else fits, you won't get that much more power with 135, you can increase the HP with step head pistons. Engine kits to do that are available from this site and Bates Corp, etc. In the last couple of years my 113 Super A and C were converted to 135 and 123 cu in, respectively.

That block # should be 354898 or is there another one I don't know about?

Thanks, sounds like the 123ci is the best wasy to go with the stepped head pistons. I"ll give this a try.
