8.1 vortec into 1979 k30

[AuroraGirl]

I was able use my psc power steering pump with the 2500hd alternator bracket. The 8.1 oem power steering pump uses three bolts on the face and an extra bracket in the back. I swapped the studs and bracket from the oem pump onto the psc no problems. Also got the Sanderson bb-8 headers test fitted with no problems except the driver side knock sensor is real close to the headers.

they are both the same pump, why wouldnt it work lol

But your pump is improved, it appears they put a bearing in the snout? Or is that just a bushing

Hey, what new flywheel did you get? If you bought the one that is supposedly specific to the 8.1, did you by chance compare it to your original 350's flywheel?

I ask because the GM part# for the 8.1 flywheel also shows as working with the neutral balance 396 and 427 engines... which in turn, should be the same application as a 350 with 2-piece rear seal.

350 with 2 piece is the pre 86 or so engines?

Lol, that was hard to read.

I just can't figure out what would be different, because they supposedly are. They only thing I can figure is that they are manufactured to a different tolerance for the crank bolts. But I don't want to buy a $200 flywheel if I already have a couple in stock that will work.
