umm.....on your '88 it probably won't make that much of a difference....it barely made one for my '91

(mine's a higher output motor, and I heard that it's even less for the older ones)...probably not worth getting unless you've got lots more planned for the truck...in my opinion, anyways....
I still haven't seen you or your truck...you should come out one day...or give me a call....881-CHEV
and umm...I don't know maybe this is too sensitive....but were you the truck there when Bjorn crashed?
