I found what I think is the factory build sheet for my 72 H/O. So I searched the threads hoping to see a description of what the Y60 is which is located in box 13 of the COPO F & SO and couldn't find anything. Anybody ever seen one of these? I'm not sure where or how the previous owner got it but it was with the 3 owners manuals and original bill of sale from Romano Oldsmobile in Syracuse,NY. I'm curious about this car's history because the seller told me this was one of 6 H/O's that were sent to dealerships to be drag raced in order to promote sales. My car is a hard top and no rally steering wheel, no tilt column, no AC, crank windows, non-electric seats, an electric fuel pump near the gas tank painted the same blue color as the engine block, and a GM 12 bolt 3:73 positraction rear end that looked like it had come originally with the car. When I was young (1977) my buddy had a W30 72 H/O that I wrenched on and I remember that car and the non-posi rearend quite well. Mine is a W45 car.

 

Just found out this is called broadcast card by searching U80 thread which is apparently for rear speakers??? Might have to call bs on the seller. Why would a drag car have rear speakers? Mine showed no trace of rear speakers but did have a dash speaker when I disassembled.

 

Not a build sheet. That's called a broadcast card. There are guys that can help you with the codes, stay tuned.

 

Not directly addressing your question, but I do remember Romano Olds here in Syracuse. My dad bought a Cutlass there. I don't recall them being performance orientated where they would campaign a drag car.

 

Y60 is Convenience Group. That doesn't sound like something that would be specified on a drag car either.

 

Just to explain the "convenience group". It consists of trunk and under hood lamps, ashtray, courtesy and map lamps, instrument panel-control lighting, glove box lamp, roof rear quarter lamps, rear door entry lamp switches for 4-door cars, a visor vanity mirror and a rear view mirror with an integrated lamp.

If the 'BODY NUMBER' (middle of the top row) on this Broadcast Card matches the sequence number on the 'Body By Fisher' cowl tag then this broadcast card belongs to the '72 H.O. you now own. If this number isn't a match then you have a broadcast card from another car....

 

FYI, these are Regular Production Option (RPO) codes, not "COPO" codes. Here are all the regular production options available on a 1972 Supreme (which is what the 72 H/O was based on). All of the items you mention that are not on the car were extra cost. It is entirely possible that the car was ordered with minimal options. Whether this was done for racing or not is unknown. Depending on the specific class being entered, there was a weight break that was optimum. Frequently savvy racers would option cars a certain way to optimize the weight break for the class they were entered in.

 

Thanks for the info guys. I think a rumor has been put to rest. Hopefully I do run this down the local drag strip here in Cincinnati called Edgewater this spring of 2020. Hopefully a mid 12 second pass? That is if I can figure out how to drive the Gear Vendors splitter I installed. Hard to get the hang of that thing in manual mode. Might be user limited if you know the feeling.

 

Unless you are using the GV as an underdrive, there is no reason to even engage it at the track. Splitting gears not only is unnecessary, the shifting slows you down in the quarter.

 

Joe by under drive does that mean 1st,2nd,2nd over, then third? I was on gear vendors website and this is what they were recommending for the three speed auto TH400 for drag racing. I can do that. Trying to split each gear on my test drive on the local straight stretch of highway was crazy time.

 

Underdrive means turning the OD unit around so it acts like a steeper rear gear set for better acceleration.

In any case, gear splitting on a TH400 is a complete waste of time. Do you really think you need another gear ration between first and second, or between second and third? At the drag strip you simply leave the GV off (so you have 1:1) and drive the car like a normal TH400. Turn the GV back on when you drive home.

 

I’m with Joe on this.
I have a GV behind a 496ci with about 630hp & 3.90 gears.
It hustles through 1st gear in a heartbeat, so I thought I could split 1st to keep it in range a bit longer.
Nada. No gains to be found.
I played with splitting different gears on each run.
I may have gained .01 +/- buy splitting 3rd because I sometimes hit the rev limiter through the traps but it’s not worth it.

They’re great for the highway but they’re not a performance enhancer.

Good to know this info. Thanks guys, my previous experience has been limited to f-bodies with manual 4 speeds. I have never run an automatic down a timed quarter mile.

 

By the way that video is buttkickin!.
