I picked up this 62 nova for the kid n me to build, i was told the motor was a 235. the guy said it was a screamer till 1 hydraulic lifter went bad. then while it was sitting in his yard someone stole the offy 2x1 intake n carbs. so i pulled motor, tore it down, first thing that caught my eye were the pistons.(i listed question "261 pistons" last week.)pistons say "jahns" inside. after some research i found it to be a 261. cast #3733813. cam says 272 on end. block very clean, other than the lifter motor seams sound. ive read the bore should be 3 3/4. is that correct. my pistons are 3.865 havent mic. the bore yet. just had a buddy mic. piston while i had it with me. also read some 261's were punched .125 any help/knowledge would be apprec.
