Re: Manifold question

Wobbled out? Do you mean drilled out, or plugged up?

Re: Manifold question

a small block chevy is a small block chevy.....tbi intake will bolt on, tpi intake will bolt on, and carb intakes will bolt on....only main difference is the 87 up head two intake center bolts on each side are at a different angle....their are a few othe exceptions i.e lt1, lt4 and vortech heads....

Because for the past few months Ive been buying parts for a tpi swap, and the intake manifold I have is for an 86 lb9, and Im installing my tpi stuff on a 91 l98, if that manifold doesnt bolt on, thats ok, I decided to go with an edlebrock base anyway.
