Re: Big Block Chevy smog ID help??????
Your smog pump assembly is for 1969 307 and 327 engines with standard transmission. The "293" diverter valve is what makes the assembly for 307 and 327 engines - "295" diverter valve was used on 302 and 350 engines with standard transmissions
The date is missing the first number which would be "0" - "1" or "2" so the date could be "069" or "169" or "269" the day of assembly and "9" is the year - 1969 the last number "1" is for the shift - 1st shift and "S" is for Chevrolet classification
