3.1 vin D shortblock

[GDSfl]

Does anybody know if everything on my 1985 fiero 2.8 vin 9 will bolt up to a 1994 3.1 vin D shortblock, THX

[robertisaar]

is that the TBI 3.1 from the U-vans?

[GDSfl]

Yes for minvans chevy,pontiac ands olds. I understand this motor uses cast iron heads like my 1985 2.8

[robertisaar]

it should actually be the same block, except it would be clearanced for the 3.1 crank...

so it should all bolt up. why you would want to keep the iron head stuff, i have NO idea...
