2.8 \"tricks\"

hi all, new to the chevy board. I 've got an 87 ext. cab S-10 flatbed that I use in hotshot business. Is there any tricks to increase fuel mileage and maybe the power? It's got the 2.8 and auto tranny. Completely stock with 150 k miles.
BTW, does anyone know what a factory shortbed( truck bed) in very good condition is worth?

I have an 87 S-10 long box 2.8TBI. SOme things that you could do are flip the air cleaner lid upsidown to allow more airflow. CLEAN YOUR FUEL INJECTION. that all i know of.

You might look into a set of headers from edlebrock as well as their cat-back exhaust system.

Re: 2.8 \"tricks\"

Do the air cleaner flip as suggested. A K&N air filter will help. Jack up the timing to 14 degrees BTDC (consult the manual if you don't know how to short out the diagnostic plug).

If you're handy with a hole saw, bore out the intake manifold and bolt on a Holley Big Bore TBI, or get a used GM 4.3 TBI from the wrecking yard (same size bores as the Holley). Use a base gasket for the GM 4.3 TBI as a template to lay out the holes.

The cat will help; a 2-1/2" exhaust will uncork it nicely. Magnum Roller Rockers (under $150 from Comp Cams) in the 1.6:1 ratio give more lift without changing the cam. Your valve covers are probably leaking anyway, it's a good excuse to change the gaskets while you're in there. And look at the distributor, usually it leaks oil; when it's all torn apart the distributor is real easy to get out to replace the $1 O-ring.

Hope this helps.......................ed
