I posted in the new members section about by 87 GN “New Member WNC”. All the parts that were mentioned is now irrelevant since finding out the the car is needing to be completely rebuilt. The transmission is trashed as is the motor. So here we go, down the rabbit hole of turbo Buick builds.

The block is currently at a machine shop getting bored .020 over.
I’ve purchased a GN1 long rod stroker kit
ARP fasteners
Calico bearings
Revolution X 212/218 112*roller cam
Holley HP EFI
Hydroboost conversion

I figure if I’m this far in, the old pt70 should probably be replaced too. I’m looking at the HPT 6466. Let me know if you have any other suggestions. This will mostly be a street car. I live in the mountains so suspension and brakes are in the near future and I like the “pro-touring” look.

New parts.
The transmission is also being rebuilt. It was originally built by PMAC so I’m hoping that most of the good parts in there will be reusable.

Wow! I’m sorry to hear the news, but am glad you’re committed to making it right.

Thanks. I’m sure it’ll be worth it in the end.

New turbo!

With the way the face of the ft cam brg bore is chewed up I look at getting it repaired and install a thrust brg.

Thread 'How to repair cam thrust surface on your block.'

Jan 11, 2017

My comp 212/212 roller non billet cam was eating into my block. The way Richard Clark showed me how to repair it was to machine the block on a mill, then install a bronze washer cut out of bronze shim stock.

This is the before pic, notice the thrust surface near the oil galley plugs.

This is the washer. It's .040 thick. Not pictured we drilled a hole for oiling.

Here's the brass shim stock

This is what my cam looks like.

Setting the block up on the mill

Here we are indexing the bit to a surface on the block that's...

Thanks for the advice. I can’t see any of the pictures though. Could you attach a link or possibly send me the pictures directly so I can share with my machine shop.
Thanks.

Thanks.

The link is in my post.
As for the pics.. They're most likely gone when the crash occurred.

I don’t know if this link will work.
I saw the post was from Steve V. I searched “cam bearing block repair” on his facebook.
The link didn’t work.

Well, that didn’t work either.

I appreciate the effort. I’ll try to explain the information I’ve been given or at least mention it to the machine shop, but without fully understanding and seeing what I’m trying to an achieve it’s going to be difficult. Hopefully they know how to address the problem without me trying to explain.

Lol, I also have a Volvo s60r track car. I’m well versed in oil leaks and cash dumps.

The guy that designed the engine hoist also designed the V Sicks Buick..........
Apparently, he wasn't selling enough hoists.
