My truck is a 96 model extended cab 2wd stepside. 4.3 automatic. It's all stock even down to the air filter except for the shift kit which doesnt really help anything anyways. The truck I'm racing will be my bothers 93 model 1st gen standard cab 2wd 4.3. They both have 90k miles on the engine and both have 3.42 gearing, He has a Flowmaster muffler which I don't see helping really. So who do you think will win this race? We're planning on racing from about 15-90 mph. Btw his 93 model runs a little stronger than any of the other 1st gen S10s I've ridden in. So do you guys have any predictions on the outcome?
