L98 was TPI, not TBI. So it would be an L05. Being a 4 bolt it was most probably originally from a 3/4 ton or larger truck or chassis. Most L98's were 2 bolt with the possible exception of the Vette L98 which had TPI and aluminium heads so it's not one of those.

You're going to have to look in the lifter valley and see if it has provisions for the roller cam spider. 86-88 can go either way.

This is what an L98 will look like in the lifter valley.
