I am restoring my 65 GTO. Although the engine is a 400ci, from a 67. I will be staying with the original heads, and it does have a tri-pwr setup, with a 4-speed. I would like to get as much out of this setup as possible for maximum street performance. I will not be racing it. Can anyone recommend a good performance cam, with a nice lope without being too radical? Also, would there be any real benefit to changing the fuel line from the stock 5/16" to 3/8"?
Thanks, Rob T |

Stock fuel line should be ok [img]/infopop/emoticons/icon_smile.gif[/img] get an electric pump or a Good high perfromance manual unit.
Cam, well that depends on what ya wana do and what gears you are going to run and what converter you have. the 068 cam may be just what yer looking for..there is a post about the 068 cam in either the race or street forums check it out for Cam stats. it would give ya decent idle but maintain that bad boy sound [img]/infopop/emoticons/icon_smile.gif[/img] Mike |

Stock fuel line into the distribution block is 3/8, with 5/16 going from the distribution block to the center and rear carbs.

Rob,
As I understand, you are using the '65 heads on a 400 block. Just remember that the valve reliefs in the pistons are not in the same location as on a 400 block. You'll be ok as long as you don't use a cam with too much duration, or too much lift. But that manifold will fit the later 400 heads, so why not use a good set of later heads, with the bigger valves, and you could go with a bigger cam for that lumpy idle and better performance! Bill

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
