If you really meant 327/350 hp, then Dave's answer is correct. However, if you actually meant 350/350 hp (i.e. 1969-70 L-46) then the rating for the Rochester Q-Jet used for those applications was about 800 CFM.

Re: Thanks to you both but...........

I was wondering what the cfm spread between my 327/300 and the 350/350 was with the transition from 1968 to 1969 small blocks.

Do you also have the compression ratios at hand? I thinking the 350/350 had 11:1 or 12:1 My 327/300 I don't know.

Thanks for getting back to me,

68-69 Carb CFM was the same from '68 Quadrajet to '69 version, regardless of HP rating. The Advertised CR for the 350hp was 11.0 to one in both years, and the 300hp was 10.25 in '69 and 10.0 in '68.
