Yes I believe so. Hell you can use the regular 3.1 intake plenum as well. Plus if you wanted, there are threads on doing a 3100 top swap with both the intake and heads to gain more mechanical H.P.

What year?  If it's a 90, you can use any 90 and up lower 3.1 manifold.  If it's an 89, you can use any 2.8 manifold.

I think 88 to 93ish 2.8 should work. I might have a spare laying around I can look for it some time this week.

2.8 lower intake is different from a 3.1.  I didn't know they were even made after 89. As far as I know, 90 and up got 3.1's to replace the 2.8.

I don't know about the 2.8s I meant the 3.1s went up to 92

The 2.8 and the 89 LG5 have the pcv port on the lower.  The 90+ 3.1 has the pcv port on the upper.
