1967 327/350 would have one of the following block suffix codes: HD, HP, HT, KH, ZI, ZG, ZJ. In 1967, 327's were availible in the following HP's: 275, 300, 350, and 325. PM me with more info on your block and I can probably tell you what it came out of if was passenger car. The 327 was probably the best SBC that Chevy ever made, including the 350. They're high winders and were able to develope more HP per cubic inch than any other small block from the factory. Others may tend to argue this fact...but they're extremely reliable.
