Re: tbi in a L98
What year intake & what year engine? You'd basically be building a L98 version of the truck engine, which was a TBI 350.

Re: tbi in a L98
Do the valve covers have 4 center bolts or the perimeter style 4 on the edge?
If they are the 4 center bolts, then yes, it is a 87+ & they'll bolt together just fine.
