This intake was used on all 69 BB engines with a hyd lifter design except 427/390, 400HP Corvettes. This intake does not have an oil splash shield. Colvin's does not have the carb # you called out, however, check to see if it could be 7029203. That is as follows: Carb: 4MV Year: 1969 Model/Eng/App. Passenger/Chevelle/Caaro/Chevy II 350/255,300HP, S/T Sam mockingbird812 Jul 29th, 04, 2:36 PM Freshayr, The info above was for a Rochester Carb with Auto Choke Remote. I don't know CFM. Not fluent in Rochesters so better get someone else to cover the "1 y" portion of the code. The 0279 is: 27th day of the year (julian date) and the "9" indicates the year of production or 1969, therefore Jan 27 1969. Sam | ||
