Easiest way to document a 72 is to look at the 5th digit in the vin. It should be a V for a factory stage 1 car. Anyone could have swapped valve covers
The motor has been built to Stage ones spec's It is in a 1972 GTX clone. The motor came out of a 1970 GTX.THE 1970 CASTING 1231718 455 ENGINE FROM A REAL GSX IS FULLY BUILT TOBUICK STAGE 1 SPECIFICATION BUICK HP HEADS AND INCLUDES A ROLLER VALVE TRAIN PRODUCING OVER 420 HP AND FAR OVER 500 LBS. Is what I am being told BS?
I would be very skeptical. Any 455 can be built to stage 1 specs. There is a 99.9% chance it didn’t come out of a “GTX(GSX?)” since 678 were built from the factory, a handful being stage 1 cars. You would also not be able to authenticate that, nor should it matter because the car it currently is in is not the same GSX. Any mild build 455 should produce 420hp, 500+ tq if done right. Do you have a link to the car/motor? If someone wrote GTX in an ad multiple times, they probably don’t know Buick’s and I would be skeptical taking any of their info at face value.
Well said Louie !! Now about the rent on that engine cradle of mine you have ............ lol Are you going to the GS nationals ??
I am the one that typed GTX. My mistake. My Dad had a GTX when I was younger. I keep typing GTX in stead of GSX. Still going to be a nice car when I am finished. Picking it up Thursday to start. Adding replica wheels with redlines, front spoiler, GSX striping.
This is the description I got. THIS CAR STARTED LIFE AS A SUPER NICE RUST FREE LOADED UP 1972 REAL BUICK GRAND SPORT THIS GS WAS THE SUBJECT OF A GSX RESTORATION CREATING A VERY DESIRABLE CAR THE 1970 CASTING 1231718 455 ENGINE FROM A REAL GSX IS FULLY BUILT TOBUICK STAGE 1 SPECIFICATION BUICK HP HEADS AND INCLUDES A ROLLER VALVE TRAIN PRODUCING OVER 420 HP AND FAR OVER 500 LBS WITH EXCELLENT INSTANT THROTTLE RESPONSE.

SIMPLY BEAUTIFUL BUICK WITH ITS ARROW APOLLO WHITE STRAIGHT BODY WITH PPG BASE CLEAR WET SANDED AND BUFFED PAINT DON’T MISS THIS BEAUTIFUL RESTORED REAL GS.
Now that description sounds like a good car- the only inaccuracy I see is Buick designated their through exhaust bumpers as code N-25, not N66. It was an option available on any 71-72 Gran Sport. Sounds like a fun car that is most of the way there. Stick around here you will get plenty of help!
Not sure on the nats yet, Lou. Will hopefully know by the end of the month. The cradle is waiting for you shoot me a line when you want to meet up!
