There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

HP is about 100-140 depending on who you believe and how you measure it. The head is the high compression 235 head. The '53 Corvette version produced 150 HP and 227 ft-lbs of torque with a more radical cam and triple sidedraft carbs.

The 3836848 head is the highest compression of all the 235 heads with the biggest valves and best flow of all of them. It's only 8:1. See casting numbers for more info. The list is not complete on the block castings. The Blueflame 235 is the car version with a fiber timing gear and hydraulic lifters and the Thriftmaster 235 is the truck version with aluminum timing gear and solid lifters. There is also a rare Corvette 235 with a hotter cam and sidedraft carbs. There is also an earlier splashoil 235 offered before 1953 that looks like a 216 and shares the dipper rods. It is referred to as the hi-torque or jobmaster 235.

It is rated at 140 gross horsepower. 128 net horsepower according the spec. plate in my door frame. However, your casting date, K2255 is different from mine. K2255 translates to the to cast date November 22, 1955 (K=11th month= November, 22 is the day of the month. 55 is the year).
