    Thank You all for the kind words on the car as well as to interface2037 for posting the vid. That is me and my car in the video. For those wondering, I do still have the car and have no plans on selling it. I'm currently putting together a new website to showcase and broker other Classic Buicks. I'm expecting to open this site by May 15th 2010. If anyone's interested you can follow me on twitter @BuickHorsepower. I'll let everyone know when the site is live.

    Thanks Again,
    J.K. Chamberlain

    At a Buick Nationals event some time ago Dennis Manner who headed the engineering team that developed this engine said the Stage 1 produced about 375 hp.

    the coolest thig about back then is gm ford chrysler would say the car has 375 hp but it realy had 450 hp!!! just to fool the insurance companies but they caught on so did the stupid emissions laws big drop in hp and torque in 1972 and 1973!!!

    The suspension looks like its original, which is cool the way the car moves and bounces a little, looks like its out of movie.

    This is from 1997. Twelve years ago. Which is wierd cause it's hard to tell when you watch it. The host still looks the same.

    You also have to look at the tires and suspension products they had in 1970, they aren't nearly as good as what they have today. A good set of street slicks and some drag shocks will dramatically improve launch in those old cars, and that was an area of concern for the GS/Chevelle/Cutlass and GTO (and most other muscle cars). I don't know of many cars that are being raced today that use the old style tire and shock packages they used 39 years ago.

    That must've been in the non "switch-pitch" converter cars, because I hear on a regular basis that automatic Stage 1 cars can run in the 12's. Whether they are tuned or not I don't know, but I do know that they retain all their stock components. Also, my Stage 1 had marine style heads on it, don't know if that makes a difference, or if all the stage motors had them, but I do know they were offered from dealers in a drag-pack with marine heads and a stage-1 cam.

    In the 70's Kenne-Bell specialized in Buicks. In Hot Rod Magazine they outlined a hop up procedure using a stock 1970 Stage1. The stock baseline with 11 inch slicks was 14.0 at 100. The mph shows it could do 13.40 but not with a stock converter, suspension and street tires. Car Craft tested a GSX in 1970 and ran 14.28/100.5. They got it down to 13.66/99.8 with slicks and standing on the converter. I have the articles. GSX motor was the exact same as the Stage 1 No Stage1 ever ran 12's stock.

    My GSX ran a 13.54 1/4 @ 108.64 mph in 2002 at Epping N.H. (that was a best E.T.), and I'm not the greatest driver either. That car, with a better driver than myself would easily do 12's. I have some frinds in the GS club who have consistently run in the 12's with stock GSX Stage cars, hell, some of the stock GS350's were running 13's.

    I had an untouched 455 Stage 1, the factory torque Rating was 515 FT/LBS and the stock HP rating was 360 from the factory, dyno tests of stock GSX Stage1 engines routinely put the HP numbers somewhere between 415 and 425.

    No its not Super Stock Hemis and 426s ran 12.5 to 1

    sigure, no it wasn't the 350 Buick had a tiny bore of 3.80 inches vs like a Chevy at 4.00 inches.

    I'm a big Buick fan dont get me wrong. I have a 430. The advertised comp ratio of the 70 Stage 1 went from 10.0 to 10.5. The larger valves took up more room in the chamber. In the real world the compression is like 9.25 as the piston is way down in the bore. The stock Stage 1 cam is 210 degrees on the intake. Thats not a big cam and is close to what was called an RV grind back then. Nearly same as the 440 Magnum and Pontiac 455 H O. An untouched showroom stock Stage 1 would run 14.2/100mph.

  24. 04GT40th says:

    The Stage motors had better compression ratio's and a lumpier cam than your typical "luxury/stationwagon" motor. And a stock GS Stage 1 would run the 1/4 in under 13 seconds, right off the shelf. I owned a '72 Skylark with a stock '70 Stage 1 engine and it ran mid-13's all day long, and that motor had 110,000 miles on it! Don't underestimate the old iron!
