That's why I could wipe any Grand Prick off the map...the Rotos were garbage. During the disastrous Roto HydraMatic years of 1961-63, Pontiac wisely reserved the "real" HydraMatic for their top of the line Bonnevilles, while saddling the lesser cars (including the Grand Prick) with those cheapie "Slim Jim" disasters. Oldsmobile wasn't quite so smart. My '62 Olds Starfire had a Roto. What a waste. Good road fuel economy, though. |

A friend had a ' 62 Cataliina I did some work on and drove it. base 389-2bbl keep in mind these engines were originally designed and built when gas was a dime a gallon in the 1950's- any old timer will tell you- who cared about gas mileage- gas was cheap |

The paragraph clearly states that all Pontiac V-8 engines would receive threaded rocker arm studs beginning with engine #709986 which was assembled on or about May 7, 1973 and would carry throughout the remainder of 1973 engine production and on to 1974. What has been proven as an attempt to save material costs and a step in the machining process as well as to eliminate the need to stock a specific yet redundant part, Pontiac engineering streamlined production by discontinuing the pressed-in stud installation process and machined all heads for threaded studs. snip Reason: PRESSED STUDS FAIL. not on a Pontiac they don't- try removing one sometime almost all the small block Chevys had pressed studs as well |

They were quite common. ANY run of the mill Pontiac from 1975 to 1979 had screw in studs as well. snip Well, shazam. By 1975, I'd never touch a Potty-tank again, and all my experience was with the "good" Pontiacs prior to '65. I had a 421, and it had pressed studs, although they never pulled out. I don't mind educating you on this at all- snip You couldn't educate a mealybug on anything. Your driving a Honda because of gas mileage alone. In all other respects, your Honda is inferior. snip Let's see...it's lasted almost 30 years now. How many 1970s GM cars have lasted that long? Answer: VERY FEW. And if you had an old Poncho, you'd have a ball with it.snip Obsolete fodder for the crusher, if anything after 1964, AFIAC. I'm starting to get the impression that when you went to UCLA, those liberal professors friggin' brainwashed you- into thinking anything made in USA or anything patriotic is bad. snip What a moron! Typical "proud to be stupid" right wing justification for their own stupidity. I see where "****us In The Family"'s Hitleristic learder, James Dobson, is going to try to steal the election this time out. Ain't gonn work...all the church nutters are already registered, and, as has been proven in '04, they've already hit the polls at their maximal strength, and are losing clout. Dobson will suffer the same fate as Raphie Reed, you watch. All those delusional church 'tards do, eventually. stick to the subject- in this case, I can run rings around you easily. Vintage cars have been an occupation and hobby of mine for 25 years now. The most powerful Pontiacs were made from 1962 to 1970. Compression and engine size peaked in 1970. The highest factory released HP rated engine was the 1963 SD421 at 410 HP. Next highest was the 1969 428-4barrel- made 390 HP rated. I frequented many Pontiac race meets, and have built about 60 of the engines, for myself and others. They can easily make 650 HP with basic bolts ons. Nunzi Romano of NYC made 746 HP on the dyno with his 455. There is a complete Pontiac aftermarket that has sprung up- they now make new replacement blocks, heads, crankshafts. So you're wrong there. Take a look for yourself, mr. know it all... http://www.nunzi-pontiac-expert.com/ http://www.krepower.com/ http://www.jbp-pontiac.com/ http://www.spottsperformance.com/ |

By 1970, GM was "decompressing" V8s in anticipation of the 8.5 limit in 1971. The highest factory released HP rated engine was the 1963 SD421 at 410 HP. snip '63 was a good year for Pontiac, so was '62 and '64. Anything past '65 was garbage, as was most anything from GM. "Decontenting" had begun in earnest. I frequented many Pontiac race meets, and have built about 60 of the engines, for myself and others.snip Uh huh. Nunzi Romano of NYC made 746 HP on the dyno with his 455. snip 'Eh, compare Nunzi! Che c'è di nuovo? È che questo asino Nudo dell'asino è un bocciagalupe? |

Once into third gear, they acted like a "real" HydraMatic, but off the line, you'd just sit there and wind out until the first shift point. keep in mind these engines were originally designed and built when gas was a dime a gallon in the 1950's- any old timer will tell you- who cared about gas mileage- gas was cheap snip I did, even back then! That's why I liked my '55 Starfire...25 MPG on the road, even back then. |
