PONTIAC - "The Super Duty Story" Part 1 of 3
Pontiac had an SD engine program in the late 50s early 60s, and later/briefly again in 1973/74 with the SD455. This video is regarding the FIRST Super Duty program.---In only a few years time during the late 50s early 60s, Pontiac MORE THAN DOUBLED their V8's horsepower output (described in this video), while using/keeping the same V8 engine block they used thru 1955-81. Even though the same block was kept, from 1955-62 the cubic inch displacement grew much larger than the initial 287 cuber it started as in 1955. It grew to a 317 347 370 389 and finally a 421 cuber in 1962. It eventually maxed out at 455 cubes in 1970. By 1970 ALL the other GM divisions were producing engines at 454 or 455 cubes (500 for Cadillac). PONTIAC WAS THE ONLY DIVISION still using the same block they used in the 1950s on engines that had a much smaller displacement -- 287 cubes. The 1955 287 displacement would remain the smallest displacement ever used in the Pontiac V8 block all the way until 1980/81 when a 265V8 was produced. Since less durability was required for the smaller displacement, the block was decked/butchered/lightened on the 265/301v8s of 1980/81. Prior to 1980 the block had never been decked/butchered/lightened. The 1980/81 265/301v8 blocks were about 200 pounds lighter than the 1955-79 blocks, and only 25 pounds heavier than a Buick 231V6.





Firing up A Brand New Chevy 409 Engine
My dad and I built a Chevy 409ci engine, and we fired it up for the first time today. It has a roller camshaft and valve train setup, so it didn't need the always worrysome break in procedure that a flat tappet engine requires. This video is from the second time we ran it, as we had to shut it down on the first try, due to a coolant leak. All of the smoke is from the anti-freeze on the headers, and the fact that they're brand new headers. Here's a spec list on the engine: 1963 Chevrolet 409 block (stock bore) 1961 409 forged crankshaft Stock connecting rods 1963 high performance forged pistons 11:1 compression ratio Clevite bearings Hastings rings Felpro Gaskets ARP Main Studs, Rod Bolts, Head bolts, and accessory bolts Edelbrock Performer RPM aluminum cylinder heads Comp Cams hydraulic roller 236/242 duration at .050-inch lift, .578/.593 max lift, 110 LSA Comp Cams roller lifters, pushrods, Comp Ultra Pro Magnum 1.7:1 rocker arms Edelbrock Performer RPM dual quad intake with dual 500cfm four-barrel carburetors Edelbrock as-cast finned aluminum valve covers (air cleaner not pictured) Edelbrock aluminum water pump Pertronix billet distributor, coil and plug wires Hooker 1-7/8-inch Super Competition headers Engine break-in and initial tuning is being performed on a home-made engine run in stand, complete with a battery, fuel supply and cooling system. Stay tuned for more videos on this engine, as we tune it, in preparation for some Dyno time.
