This is all too familiar. There is a picture of a 292ci 273 engine with 8 sleeves taken in 2010. It has Indy/RHS-X heads, Jomar girdle, stock crank, Ford rods, roller rockers, push rod oiling, Comp solid roller cam and lifters, wet sump oil pan, HV pump, oil crossover (hidden by the paper towels). I had to drive from Morton, IL to Melling to pick up the sleeves and bring them back to be installed. It had to be re-sleeved because the first set of sleeves were offset and the valves hit the cylinder walls.

The cylinder head had to be repaired because the #7 exhaust port cracked and was leaking water during the dyno runs. I had three of these heads that had the #2 or #7 exhaust port with very thin casting in spots.

See post 109 in this thread.....I believe this may be 273 engine from those dyno sheets.

Is 426ci 360 a small block?
