build sheet question
Hi all,
In the production instructions box on my build sheet does anyone know what the 'SR' stands for? My car has an 'SR' block, it has the correct casting number 9773155, is there any connection?

Ron, I believe the SR stands for Special Ratio. I have several examples of Pontiac-plant built 1964 GTO with 3.90 gears, and they all have the same SR PN 174 175 in the Production Instructions box, and AXLE 39 10 APP in the bottom box.

I have a 1965 GTO and a SR casting # of 9773155 also. I thought SR stands for SERVICE REPLACEMENT?

It's my understanding that they are the last 3 digits of the front and rear Heavy Duty or Handling Shocks as in 3178174 and 3178175. The other choices would be Standard or Trailering 3186908 and 3186909 or Superlift RH 3178552 and LH 3178551.

I believe John V. would be able to offer more insight into this. I'm not certain, but I don't believe SR would stand for Service Replacement block. I can't imagine why corporate would specify a service replacement block for a car coming down the assembly line. I was comparing different Pontiac plant 1964 GTO build sheets I have, and the ones with the AXLE 39 10 note always have the same message in the Production Instructions.

I agree with riggsjr. He makes too much sense. Back in the day when we blew up the original engines, we went back to our local Pontiac dealer, gave him a song and dance about a bad engine and hopefully he'd order a new one from the factory because he had none sitting around, hence the SR. I'm not saying that the original engine was stamped SR, just the "service replacement" engine. Just my 2 cents worth-

Guys, I'm referring to the "SR" on the build sheet only, the topic of discussion here. If an engine needed replacement, then yes, a service replacement block may be used if the engine could not be repaired.
I can't imagine why Pontiac would code a build sheet for a service replacement block on a car that hasn't yet been built? The AXLE 39 10 APP reference was for 3.90 gears. The only way to get this ratio was with posi and metallic brakes, and those codes are shown in boxes 71P (3.90), 692 (metallic brakes), and 703 (posi). Mike

Replacement Blocks were supposed to be stamped SR by the Dealer changing the Block.
SR on a manifest typically meant a Special Request or Special Ratio in the 3.90 axle case. Tom V.

Also...
I see it has the "9" in the tranny box...also for the 3.90 gear speedo drive. Sounds like an interesting car at the very least!
