i have another post i am trying to figure out what motor is really in this 1991 caprice. have ran the vin number and it comes back a 5.7 tbi i was wondering how this compares to the LT1 in horse power gas milage the owener says this car has a 12 bolt posi rear end does anyone else have a posi.......standard or installed

clason69

the owner alson claims it has and LT1 in it and over sized brakes 12 bolt posi ect.

It might have posi-traction. Look for G80 on the SPID.

It does NOT have a 12 bolt, or rather would not from the factory. Crawl under the car and count the number of bolts on the differential cover.

I agree, it does NOT have a 12-bolt. At best, it is an 8.5 10-bolt...

GOOD to see you again CD! I was on Hiatis for awhile... It's good to see this list pick up where GMForums apparently left off!

BTW--how can one enlist on the B-body e-mail list? Thanks!

CD Smalley

Sure anyone can. I started making an approved list after several spammers showed up.

Come on over!
