    Do you happen to have the Sloan or Wayne Roberts report on the car (if not it would help in selling it)? Does it still have the alum front drums? Can you post a pic of the trim tag?

    Not inline and we're not supposed to comment on "for sale" ads so I'll delete if you (or mods) want, but super neat car - I happen to have a thing for low option (especially factory manual steering) GS's and it's very rare to see an automatic/factory manual steering car. I've owned four (4) 4-sp./factory manual steering GS's & seen many others but this is only the 2nd manual steering/automatic '70-72 I've seen. The other was a '71 455 (also bench seat and not a Stage 1). I'm sure there were others of course and of the batch of early '70's that were destined to be racecars there may have been a few.

    I hope whoever gets it keeps it like this. Someone originally bought this car to go fast & straight. I wish I was in a position to consider it. GLWS!

    That was a bargain IMO.

    Well I piddled around too long and lost the buyer. So the 70 lives and is for sale. My delay was the result of hearing a ticking noise coming from cylinder number 2 both when cold and when warm. So I changed rocker arms twice; to no avail. I took off the valve covers and watched the rocker arms move while watching oil go everywhere; no problem. No backfiring out the exhaust nor the intake. So I thought maybe I had a collapsed lifter. So I yanked off the intake and examined the cam and lifters that all looked good. Nonetheless, I changed all of the lifters installing a new set of Mellings. Then as often happens in my world after the fact, it dawned on me that maybe I should check the push rods. I took all of the push rods and rolled them across a piece of glass. Guess what? Of course, the push rod on exhaust valve on number two cylinder was slightly bent; enough to cause the ticking problem. A smarter man would have checked them before pulling off the intake, but not me - that would have been too easy.
    The good news is that now the 70 is running like a r@ped ape; please pardon the phrase. Mechanically the only thing she needs is a power steering conversion; that manual steering is a b and the wheel turns almost a quarter of a turn before engaging. So, in sum, the 70 is a great driver, a little rough around the edges, with big block Buick monster torque.

    I think your GS is the offspring of my '69, which also was ordered with no power steering, no power brakes, no power windows, and no A/C. As Dano said, the original owener wanted to get rid of any power-robbing options. Good for going straight, but not good for low-speed turns or parallel parking. I wish my wife would let me give yours a home next to mine. They'd get along really well.

    I thought this was a done deal a d the new owner (JohnnyGS?) had possession of it.

    I thought the same thing too, Dano.

    I thought so too but during the time I was tracking down the ticking noise he said he found a Riviera and so she is back for sale.

    You seem to have the same taste in cars that I do, judging by the C2 Vette in the background. I used to own a '67 with a big block and 4-speed. I sold it but I've kept my Buick all these years (since 1978).

    I have two C2 Corvettes
    The blue is a 427 390 horsepower with vintage AC. My project car is a 67 427 435 hp race car that I am converting back to stock. However my 72 Stage 1 I bought in 1983 and have kept it through thick and thin.

    My '67 had factory air. When I bought the car, it had a 1970 454 under the hood, but the correct intake and carbs (and triangle air cleaner) for a 427-400. It moved pretty good when all 3 carbs opened up. But I think a Buick could out-accelerate it.
