I don't know why you people insist on bad mouthing the 301. I worked for Pontiac when they came out and we had zero problems with them. Granted they don't make a lot of power but they were not meant to. They were designed for better gas mileage and compared to the 400 got much better. One of the other mechanics bought a new 1977 GP w/o AC and got 26mpg on a long highway trip. I installed one from a wrecked TA in my 1961 Chevy PU and towed a 24 foot camper with no trouble. They did exactly what they were designed to do.

Yup, it worked for me when I did it right. Not too good with some of this stuff at times, Carmine.

In any case, a 65 or 66 tripower manifold will not fit on an engine that has a regular sized HEI distributor (without trimming the manifold). The thermostat housing on a 65-66 tripower manifold will not clear the timing cover on some later engines (The "dimple" on the cover is too small.) The location of the valley pan pcv fitting on later (68 and up??) is toward the front of the pan and will not clear a tripower manifold. An earlier pan has the fitting on the rear of it. The center carb on a 65 is a Size 2 and the center on a 66 is a Size 3 carb. End carbs on both are Size 3. (The "Size" refers to the spacing of the base flange mounting holes.) The recent post by "b-man" has excellent pictures of different year tripower manifolds. |

No, I don't have an engine yet and I don't even have a car. I'm looking ahead to the future. Depending on the day of the week, I would like very much to own a '65 or '66 GTO. Preferably a '66. If it doesn't come with a tripower, I would like to have one ready for it. I see there are many out there and I just wanted to make sure whatever I buy, will fit. Besides, I like to tinker with things myself so I would probably rebuild it. I have no car purchase lined up at the moment, but I can be a spontaneous SOB at times. Just trying to gather up all the info I can for time being, Carmine.

Using a 66 carb on a 65 intake would require an adapter. That would screw up the linkage. If you get a center carb, make sure it is correct and not a Chevy. They look very similar but the correct one is internally bigger and better.

Tom V. ps A Holley #4412 2-BBL carb for comparison has the same Throttle Blades as the Pontiac End Tri-Power carbs but the Venturi is 1-3/8" in size, a full 1/8" larger vs the Rochester Carbs. 350 actual cfm per carb (rated like a 4 BBL) so a 1050 cfm set-up vs a 750 cfm Rochester factory set-up.
