Information on your GSX can be obtain from: GSX Historic Society Wayne Roberts 5721 Livemois Rd Troy MI 49098 810-879-2113 I believe the cost is $75.00 and $150 for a rush order. Mark
Thanks for all of your help everyone. Here are a few photo's, I'll get some better ones when its home safe and sound. I'm guessing the "455" badging was placed there by the dealership when they were racing it. As far as I know they never did that from the factory.
Hmm, they raced an AC car? The only other difference I can think of in the lower end besides the cam Jim mentioned is the bigger oil pickup tube and gallery used in a 70 Stage-1. Sometime in 71 all 455's used the bigger oil tube and gallery.
The car is a 4-speed. We're getting the car on Saturday so I'll have some better photos and get the production date this weekend. Here are a couple of photos of what we wish we had back. Unfortunately I can't find the photos of my WE4.
The weather didn't work with us on Saturday so we were unable to get the car. We did however go down and take some more pictures and verify all of the numbers. The car has been sitting since 1983 but we got it running! How do you like the exhaust patch? :beer Jim, the production date is week 1 of April 1970. Does that help with the "455" badge question? Duane, It does appear that there is a "B" in front of the "OE" on the engine stamp. Anyone know why there isn't anything between cylinders 5 and 7?
No I suspect someone wanted to see the numbers 455 on the sheet metal and was disappointed to not find any on a factory GSX paint scheme. I do think that date works well with the seldom seen Bud label exhaust pipe extention.
The letters normally found there like SR, SF, and SS designated models for which the 455 was intended from the factory. Service replacement engines to the best of my belief did not have those stamps. As I recall those that I have do not either. Even the stage 1 replacement engines had the GM part number for the stage 1 on the wooden crate but not on the engine short block.
Here is a link to the GSX reunion thread-http://www.v8buick.com/showthread.php?t=162108 Did you get the "X" home yet? Best Regards, Eric
Going back to the replacement block question. I have a 70 gs350 and I swear the number is B9E66449. I know the second number SHOULD be a zero but it REALLY looks like a 9 cause it matches the 9 of the ID number. There is some dirt and scratches which makes it kind hard to read. Does the 9 mean a 69 block? If so, are there differences in the block? I know the motors have different compressions, but I want to make sure my car is the 315 hp 410 tq not the less powerful 69 350 version. Any help is great appreciated.. Bob
The number "B9E66449" would designate this as a 69 replacement block. Can't tell you about the performance specs the factory engine books I have only list the parts used at the beginning of each model year. I have no "up-dated" books so I cannot say how (or if) Buick changed internal parts during the production years. Duane
Thanks Duane - I think the heads may be different and I think the 1970 heads are on my car, but you never kow until you tear into it and I really have no intention to do that anytome soon. I guess it's possible that the block may have cracked during a cold Iowa winter (where the car was delivered) and the engine was rebuild but with a left over 1969 block and 1970 parts otherwise. At least I hope that is the scenario. Thanks again. BH
