I just bought 3 quadrajet carbs and a 9799068 dated e110 manifold for my 1970 pontiac. One Rochester carburetor is from a 1970 455 Buick (7040240) rebuilt and working. Does anyone know if that will work on a 1970 pontiac 400 xh block with #13 heads and a 068 cam? The motor is going in my 70 Catalina convertible to go cruising. The others are... 7029262 Carter and it's missing some parts and a 17057202 Rochester with an electric choke complete. Thanks for the help.

Thanks for all the suggestions. I got the #13s today and they are ready to build. I'm looking at the 068 cam with the #13s for my 70 YD block. I'm putting a 1969 4bbl iron intake with a 1969 or 70 Rochester on it. That should be around 350hp? My 70 xh motor with the stock #13s already on it should be about the same too?

Thanks for the info. I just picked up a 1970 xh code motor with 13 heads I'm going to go over. I'm also picking up another set of #13s this weekend.

I have a 1970 400 YD code motor with #11 heads and want to change it to a 4bbl rochester with #13 heads. Is this a simple bolt on or is there possible valve and cam issues? Thanks

Hi I'm Kelly and I just joined foreverpontiac. I'm putting a motor together for my 1970 Catalina Convertible.
