$14,200 is the price or best offer. Orange 70 GS 455 automatic with black interior; no air conditioning, manual brakes and steering, Shifter on the tilt column; bench seat with fold down armrest. The entire drive train has been rebuilt and this GS runs, please pardon the phrase, like a raped ape! The engine was decked so I cannot tell if it is the original engine but I was told by the previous owner that it was the original. G & G performance engines built the engine. The engine has 10 to 1 forged pistons and is 30 over; honed with a Buick torque plate; balanced and blueprinted. The cam specs are unknown but it idles with a crisp rumble and raps nasty and quickly. It has a custom oil pan, Mickey Thompson headers and 3 inch exhaust with an x all of the way out the back. The tranny and torque converter were built by Circle D here in Houston and it is a true 3000 stall converter. The rear end is a 12 bolt with 4.11 gears and hardened axles. The rear control arms are boxed and the rear sway bar is present. The 70 heads were cut for Stage 1 valves and a competition valve job was performed. The entire set up may have 100 miles on it as once it was built, the owner was sent to Angola so it sat in storage for years before I bought it 3 or 4 years ago. The custom wheels and tires have very few miles on them too. The stereo is a very good Alpine unit and there are multiple speakers attached to it. This is as much of the good stuff as I can recall for the car except I will add that I heard a tapping noise so I switched rocker shafts to no avail so I changed the lifters thinking that had to be the source of the problem, but it was not. So, next I checked the push rods and found one of them to be bent slightly but enough to cause the noise. I replaced that push rod and voila the noise went away. Of course, I could have saved myself the step of removing the intake manifold had I checked the push rods first, but oh well. The next test ride did not impress me with the power I thought the GS should make so back to the drawing board again. I had an 800 cfm Buick carb sitting on the shelf so I took off the spread bore Holley and hooked up the Quadrajet. Holy Christmas! Now she honky tonks! Now for the rest of the story. The paint is a good 20 footer. The interior is good except the bottom of the door panels are not perfect. The sail panels are wrinkled because of the speakers mounted there. The non AC dash is cracked on the driver's side. All of the seats are in good shape and the carpet is fine. The body has pinholes above both rear wheel wells but behind the rear window the slight rust that was there has been professionally repaired. The trunk lid and the trunk lips are perfect. I have not had the GS up on my lift but while crawling around underneath it the trunk pan looks good and the floor pan does too. I think the GS may have been undercoated when it was new. Thanks for looking.
The GS and I are in Houston. The body plate shows: ST70 TR Z123 14 14 PNT 09B I'm sure someone who knows codes can translate these but I think the car was originally silver. Let me know if you have any more questions.
Probably 128 on the interior code and yet another with a "Z" (supposed to indicate a non-recommended color combo) for no apparent reason.
There were a lot of random 442’s and W30’s that had the “Z” in their code as well,but not all of them.
You guys know a lot more than I do. The 70 GS does have a black bench seat with fold down arm rest now as well as a tilt wheel oddly enough.
Correct - My '70 350 4-sp. is a 128 (with a "Z"). There was no 123 interior code so I'd figured 128 and that it had been changed to a 178. Regardless 123 isn't correct unless that was mis-stamped. Maybe Dave could past a pic of the tag. (Sorry Dave - This is a your for sale post so will be happy to delete and extraneous comment).
I took a closer look at the interior code andn the data plate could well be 128 as opposed to 123 due to inadequate scraping with the sandpaper
I am reducing the price on the orange crush GS from $14,200 to $12, 200. She runs great but needs to be taken care of with fixing the rust above the wheel wells and general detailing.
