Hi, just installed a 4bbl Rochester on my 70 455 engine, took off a Holley 650, I do not know what ports on the carb need to be plugged and what ones got to which vacuum line can anyone help? I tried the chassis book but it does not show a 455, Thanks Phil from Milwaukee

 

If you show a 350 4bbl then it's the same.

 

Hi, it does not show which ports are capped off and what line comes from the aluminum intake or where the O.A.I line tee's in with? Any Ideas, The book is very vague. Phil
