![]() ![]() Before the upgrades, the truck was a dog. ![]() The 3.08's seem decent now with the performance upgrades. Speaking of gears, most of these trucks came with 2.73 or 3.08 gears (mine has these). What else can I do but don't really want to: electric fans, cam, heads, intake manifold, headers, msd ignition, gears. What's left to do? Well, I don't want to mess with cam and heads so I am going to add an adjustable fuel pressure regulator to bump the pressure up a bit, a custom chip and probably a corvette servo and shift kit for firmer shifts from my 700r4. They make great low-end torque but thats bout it in stock form. Still falls flat on top but that is probably due to the horrible flowing heads and cam these TBI engines have. Just added a TBI spacer and injector spacer and those made a huge difference. I have true dual 2.25'' exhaust with high flow cats from manifolds back. Bringing this thread back, I have an 87 as well but with the little wimpy 305 tbi Well after a few upgrades. ![]()
