It does have a gas engine swap and I can't tell if it had hydra booster originally? There is a vacuum booster in there currently but I don't see any marks?

GMC 1/2 ton Suburban, '87 model year, built in Flint.
Most of the Suburbans built in that time frame were pretty highly optioned.
Note that for GMC that year the VIN sequence started at 500001. Chevrolet started at 100001.

I appreciate it, thanks. Just trying to figure this thing out lol. I'm not new to squares either lol. Glad it has 3.73 ratio and apparently a gov bomb but we shall see.

Since it was a diesel,I expected hydra booster but definitely not there anymore. Weird thing is I see no witness marks either. And a 7300 gvw seems odd but ok . This thing has a 159000 on it according to a log book I just read, so who knows what has been changed? Other than the engine lol

There are a bunch of RPO codes. I found this recently while searching my $100 beater 97 Lesabre.
