Post up a few pictures of your "race truck" I would think you might be better off learning more about the mechanics and what works and what doesn't before you start drag racing anything ! It's a LOT more than just buying a friends "race truck " and having someone "race tune it " jumping in the drivers seat and stomping on the pedal of a machine you know nothing about . It's a disaster waiting to happen and if your lucky the only thing you'll break will be truck parts and not body parts !
Brakes ?
Suspension ?
Tires ?
safety equipment ?
NEVER RUN RUBBER FUEL LINES . pushing more fuel is usually the cause of an off the line stumble rather than the cure , We all like to have fun , Don't let it kill you !
What year and model truck ?
