Anyone know?

No it won't swap over without a lot of work. And I believe that is a 8.5" rear, unlike the 7.625" in yours, so the gears will not swap over.

F-body rears are unique from 82 and later. They do not interchange with anything.

So is the caprice rear stronger?

Compared to what other rear?? A clue would be what kind of HP & TQ did that Caprice have to handle, very little in my opinion.

camarolover20

The caprice is a 350 and the camaro had a 305 tbi

87DJP2001

Check your facts. 90/91 Caprice engines 170 Hp TBI 305 & 140 Hp TBI 307

HAHAHAHAHA Thats the best one I have seen all day 87DPJ.See reread the 1st post i stated the car is a 9C1 makin it a old cop car and there for having a 5.7L and that being a 350

Compared to what rear? Are you serious?

And what it needs to stand up to doesn't really hint at the rears strength. The 8.5" is significantly stronger than the F-body 7.625", but since it won't fit, who really cares?

Try another big laugh, Who cares if it was a old Cop car and a 350, what was its output?? Not much more , then the other ones I quoted. Just anther GM rear that will not work in a 3rd Gen car. And the big laugh is on you for asking the Dumb question will it fit. .

Marc 85Z28

I believe the 90 was rated at 195HP and 295TQ. And much like the 3rd gen, the 9C1 cars are a nice platform for a performance car, even if the early models were a bit underpowered. I'm actually looking for one now in addition to my car, but I want a later car with the LT1

camarolover20

Yeah LT1's are badass I have one in my 97camaro ran 13.7's with muffler cut off.And the TQ will not be close on the 305 vs 350 with cam and other things

camarolover20

I dont think you have seen a caprice.It is kinda close
