Theirs many types of motors for vehicles. Some examples is v8, v6, 3sounder, v10, and also my favorite diesels. When getting or parching new motors look at the mileages. And look for worsen parts or damage areas on the motor. And if you just buy a new motor to build you can put upgraded parts in it and on it like blowers and intakes and gaskets, and nos hook ups , and last is my m=favorite headers and superchargers and cams. My truck that I race has a procomp cam and a super charger. My super charger builds 15 pounds of boost and that’s really ant much. My friends ranger that he races has a 600 pounds boost charger on it and it’s quick. His truck has beat me at a lot of races but I don’t get mad because, it was his dads truck who passed away on his son’s birthday when he was 8 his son wanted to race it so I helped him fix it up with some money I had. Witch made me miss a race that I wanted to do but I didn’t care I helped him out so that’s nice. I didn’t have to help him but I decided to. His truck is yellow and nice I’d like to have it myself but it was his dads and he never gets read of it. Witch I don’t blame him for not wanting to sell it to anyone. If it was mine I wouldn’t.
