I have a Pontiac SD4 engine, race prepared Getrag, Weber carbs, MSD ignition and SD half shafts that I won't likely use. I decided to go in a different direction. Unfortunately, I don't have a lot of tech data on this engine as of now. I had details in a file, but haven't been able to find the file. So I will do my best to find any answers I can. But for now...
The engine, I was told, is the same series as the SD engine that was in the official Pace Car. Here are some pictures...
Race Getrag - SOLD
Super Duty half shafts. Box has John Callies name on it.
If anyone is interested, we can discuss it here. Thanks.

What is "Race prepared" ? Is it usable on the street? Or has it straight-cut gears, etc?
As I understand it, certain parts are “cryo-treated”, supposed to make them stronger. And yes, the gears are straight-cut. Supposedly not easy to drive on the street.
If anyone is looking for something that runs on regular gas and to go to the local Home Depot in they obviously clicked on the wrong thread. The title should have been a hint.
Am interested. Sent private message and received no response.
Sorry, yesterday was super bowl, I had a big party.
As I said in my reply email, it is difficult to get to an asking price for this SD stuff because it it very specialized stuff and it isn’t easy to find comparable sales. I know what I paid for it, but I likely overpaid. I’ll see if I can come up with some asking prices, possibly today. But anything I come up with must have some supporting data and be well thought out. Fair enough?
I rolled the pallet with the SD stuff out into the sun, so I could get better pictures. I'll break this up into separate posts for each component. I'll start with the long block.
I was told this is the same series engine as the official Pace Car, which is a big reason why I was interested. I planned to build a Pace Car with the Super Duty block as a real Pace Car replica, so to speak. I figured it would be a show car and track car, since it wouldn't be streetable. Because of the specialty nature of the engine and parts, repairing it would be a pain in the ass...and expensive. So I abandoned the project. I hope to build a Pace Car replica on an 88 chassis with a Cadillac 4.9 instead, something I could drive on the street.
Putting an asking price on this is difficult. It's not easy to find Pontiac SD prices on exactly the long block I have. So I put together what I'd seen as asking prices on other Forum threads, including one that has been active recently.
KRP racing block 1500, SD block (unknown series) 800-1000 Crank 500-1000 Cam 100 Head 850 (2014), 1000 (2018) Valve cover 200 (found only one example FS in archive search, 2014)
So for the long block, with valve cover, head, block, cam, and crank, it looks like $3,000?
Block
Valve cover

Weber carbs. I couldn't find any comparables for same currently or in the past. I seem to remember the purchase price was 1100-1300. Let's call it $1,000
Race prepared Getrag. I'm hazy on the details, and hopefully the guy who sold this stuff to me will have info I've forgotten. What I recall is that some of the internals are cryo-treated for strength, and the gears are straight-cut. In the pictures below, note the safety wire on some of the bolts. One negative is that I don't remember the gear ratios. It was for a race car, but I don't remember what specific application (type of race). Road course, maybe?
In a search, I see used Getrags going for the $300 range, although most of the dates on the threads were 2015 or earlier. This is a race transmission, basically. Not sure how to price it, so make offers?
Almost forgot the half shafts. As I understand it, these were from the Pontiac Racing division. The box has John Callies name on it, along with some other GM identifications. I want to first find out if these would work with my planned 4.9 swap.
I believe this is a Limited Slip Differential

KRP is Kauffman Racing Products now known as Kauffman Racing Equipment, a long time premier top Pontiac engine builder. Hardcore Pontiac people know the name well. Novices hear the name Butler, Kauffman is what Butler strives to be someday.
If the price is right, I would be interested in the axles or at least all the packaging from them.

What are the blue plugs on the side of the transmission
Those are bolts with blue paint on them. They go into what I assume is a custom boss on the outside of the transmission, probably part of the strengthening of the transmission for race purposes.
