HB 1968 327 275 MT B, HDC HA 1969 350 300 MT A, F, X It could be any of the three. You will want to find the casting number to see which block it is, and then see if you can find the casting date. For tips, see http://www.nastyz28.com/sbchevy/sblock.php That site has the best casting codes, suffix info, and other engine stuff out there for our cars. Been using it for over ten years. Nasty Z28 has two HA codes: HA 1965 327 4 spd tran. std 275 4 full size/Camaro HA 1969 350 manual trans 300 4 A F X Check the date for the most accurate estimate of what it was.

I can't find any info on the CFM. The Holley that came on the L79 350HP was 585 so I'm sure it wouldn't be any more than that. I found a discussion thread where a guy flow tested them and said they were 582 but take that for what it is worth.
