I finally acquired my dream truck project 78 chev 4 door with an intercooled 5.9 getrag 5 speed divorced 205. I have read the basics about turning these suckers up and have done one myself but it got horrible mileage. This truck already has some good power and an hx35 already installed so I'm sure it's already turned up a little. I also have a hybrid 40/35 with a 14cm exhaust from an older project and a denny t stage II pin layin around from an old truck. This truck needs to be a tower that's what I'm aiming for. Any help suggestions. I am basically new to moddin first gens. Gauges will be installed before I really get into this project.
