Hi Pat,I finally got some info sent off to you Friday to use in the 73-75 Century GS Regsitry;sorry it took so long.
Thanks, I have been really busy lately doing my "HONEY DO" things and have been running after all the Buicks Dustin seems to find.I did not forget this project,just been on the back burner for a bit.I am always willing to get new stuff.Thanks so much for everyones effort. Pat
1973 455 stage one engine identification Hi, Do you have any engine numbers for a 1973 455 engine that would verify it to be a stage one engine? My engine number is 43H534632. Thanks! Gary
Gary, My suggestion would be to contact Sloan and see if they have a car that has either of the following Vin numbers. 4D37V3H534632(Stage 1) or 4D37U3H534632(NON Stage 1) Century GS It could also be a Riviera motor that was a stage 1 or not.Those numbers would be the only way to tell if this is Century GS.There was also a Stage 1 that came in the 73 Rivs as well, but I dont think this would be a Riv motor since the first 3 digits are 43H. Ususally, the Riv's numbers have a Y in them. Example 43Y534632. To be honest with you, I have documentation from Sloan that the last apparent Stage 1 produced in 1973 Century GS cars was in the 200's in the last 6 digits. I think its like 269600,so I am thinking its not a Stage 1,but I'd contact Sloan and see for sure.
