timing problem or crossed plug wire or even possibly a burnt valve.
The 1966 GTO only came with the 389 cid motor. You could, however, get it with the standard 4 bbl quadrajet Rochester carb or the optional tripower (3x2 carbs).
quadrajet carb but not sure what size it was. ANSWER: The DISTRIBUTOR was the same single point type used on all 1969 Pontiac V8s, except for the extremely rare optional "magnetic pulse" electronic distributors made. The timing curve and initial timing setting was varied for each engine application. The CARBURETOR was a 750cfm Quadrajet.

There are a lot of places in order for one to find out images of a 1970 Pontiac GTO. However, it is strongly suggested that one should check out from the website Hemmings.
The only GTO that came with a shaker hood was the model year 1974.
take the carb out give it a clean if not then the air filter lol
Zero. Pontiac never installed the 428 in the GTO. GM had a corporate ban on engines larger than 400 CID until 1970. In 1970, the 455 replaced the 428. ALL GTO's built from 1964-1966 came with 389's. ALL GTO's built from 1967-1969 came with 400's.
There are many places one can go to to purchase a Pontiac 1970 GTO. The best place would be your local Pontiac dealership to help locate you one. You can also try AutoTrader.
