| − | Building a straight | + | Building a straight 6 250 is not any harder to do than any other inline 6, be it a Ford or Chevy, GMC, etc. Parts aren't as common for the inline 250 as they are for a SBC, but there is info and quite a few suppliers for parts, as well as places that cater to almost nothing but the Chevy inline 6 engines. |
The inline 6 Chevy 250 should not be compared to a SBC engine. Besides the obvious differences, they share practically no parts w/the V8 engines. Because of this fact expect it to cost more per horsepower than a Chevy V8. The reward is this is not a "belly button" engine; instead it is considered "old school" and has cred because of what it ''isn't'' as much as for what it '''is'''. | The inline 6 Chevy 250 should not be compared to a SBC engine.

On the block there will be foundry ID codes, for instance "CON3". This is no help in ID'ing the engine. | On the block there will be foundry ID codes, for instance "CON3". This is no help in ID'ing the engine. | ||
| − | There may be a date code | + | There may be a date code cast into the block. Example- "A 30 2": Jan 30 of a year ending in 2. If the engine is a 250, that would be 1972. |
The suffix code (also called the "application" code) will be at the end of a string of letters and numbers (that's why it's called a suffix). The suffix string is usually a letter followed by a date code, followed by 1, 2 or 3 letter code. This is found in the area near the distributor, above the fuel pump. The suffix string of letters/numbers are always stamped in, not cast into the block like the date code or foundry ID code. | The suffix code (also called the "application" code) will be at the end of a string of letters and numbers (that's why it's called a suffix).
