Re: Mileage help please- 87 Chevy 350TBI
What I meant was there might be a taller lid out there somewhere (junkyard?) for the TBI trucks. I know the carb'd ones have taller lids for the 5"-6" high filters. If they're the same diameter perhaps one would work for you. Then I'd find an amsoil, K&N, aFe, or somebody's washable air filter element for it.
Hmmmm, tires for 16" wheels. Are they stock steel, or are they aftermarket? I've got 235/85s on my '83 K2500 w/4.10s. Next go round I'd like to test fit some 255/85 tires and check clearance. You mentioned this is a weekend driver, will it be going up in the mountains or doing any off roading?
