With the fine help on the forums I have successfully brought back an older 235 engine back to life. I am now getting ready to work on another engine and need some Identification help . It was sold as an original 1956 engine from a 3100 pick up.
ID casting numbers Con 3 L65

009076 IF56 X (stamped on machined plate left of distributor)
My guess is Flint Michigan 1956 3100

Other casting # below distributor 3837004 (the third # looks a little suspect but that`s how these old eyes see it.)

16 bolt head. #3836848
Was just wondering how they differentiated 235`s from 261`s as they both appeared to be made during this time period. Interested at this point to see if it was possibly a 261 I purchased or if its the 235. Also wondering if this would be solid lifters as the stock set up. I can always pull the side cover and disassemble a rocker and pull the pushrod to see for sure. Any help appreciated.
