ill be honist most of what happens with truck is really based on makeing it more dependable. Timeing gears are for the fact I hate seting time and cam is just in case I change intake I know its a stock cam and might get demolished by carb. But for now its tuned and auto choke works, fuel filter is taken care of( glass aftermarket) and I can do what I like with it jump in when mood strikes and drive it or if kids car fouls up he can use it. And that's the goal its just a toy to play with so not a dragger but dependable and if I whant to stand in its a** I can.
