fuel injection is the rapid injection of fuel directily in to the engine fuel injection on semi's has GPS in it so it can monitor the amount of fuel that is injected in to the motors while in certion areas, as in more fuel while in the mountains when it reqires more power to go up steep hills or less when in a desert where it is flat and less power is needed. hemi is a dodge motor that has a hemispherical combustion chamber that alows better cerculation of fuel. it got its name from that same reason. GTO stands for Grand turismo otimo. trans am was a race for stock cars off the production line. one of the ways to tell a big block to a small block is the valve covers on a big block are wider than a small blocks. mopar shifters were long and required a long stroke to shift. the 3 cars that remained the same were the camero, the fire bird, and the trans am. the body of a corvette is all fiberglass, the pinto had the gas tank directly in the back of the car, making that if you were rear ended it would most likely explode, this is what ended its production. the first person to drive a hemi dragster to the winter nationals was don garlits. john delorian helped make the GTO and he desingd the delorian. traction bars conect to the leaf springs to prevent it from buckling, when motor is producing power the torke is put to the pavment with the tyers, but the torke must move threw the axel first, making the axel twist, becouse the leaf springs are conected to the axle, they buckle, one end of the spring, moves down and the other moves up, making the tyers bounce,( this is why you see  single lines on roads, its from some one peeling out and the one tyer jumps off of the ground) the leaf spring conect to the axel, not alowing the wheels to bounce when it buckles, becouse it doesent buckle with traciton bars on it. most ta/fc (top alcohal funny car)have about 1500- 2000 horse power depending on track conditions. a sling shot dragster is a dragster that has the enigne in the front of the driver, but has no body, just a aluminum shell around the chassis the smallest production car ever made by the chevy motor company was the 1972 vega. a muscle car is a small car with a big block or a large cid engine small block. rat rod is a reg car with a big block in it. there is no difrence between a small block motor mount and a big block motor mount.  to a point puting air ducting on a car would make a turbo efect but only to the extent of a ram air. ram air is a large quantity of air that has enought psi stored in ducting to charge the motor by forcing air in to the fuel injectoin/carburature but not enought to result as a super charger. a 3 point roll cage has a bar that comes from the roof bar to the passnger side, with the shoulder bar going only to a point of the roof bar that leads to the passenger a 4 point has a roof bar that extends from bolth sides of the car, with a shoulder bar all the wasy across, and reinforcements on bolth sides that lead to the back off the car.  the term horse power came from a man working as a coal miner, he found that a heathy horse on average could pull 500 pounds of coal on its back for about 300 meters. alcoahal motors have lower compersion that a nitro becouse nitro is a oxegyn containg fuel. police dectors only recognse the radar that they use olnly when in use. almost every car in america has fuel injeciton. the drive shaft would shake on a impala from the position of the motor and the wheels. a 4 speed mucie is smaller than a aoutomatic transmission, there was a swiss buik, not becouse it was actually swiss but its name was swiss cheese for the fact that there had been 1 inch holes drilled in the frame to reduce wait. modern chassis on funny cars and dragsters are made of chromemolly. the alcohal funny cars need wheely bars more than nitro funny car even though they have less power, becosue the produce more rpm and lounch a blower on a alchalhal motor or nitro must have  13 thousanths clerance for it not to weld itself together from the plate and the bearings, cid is the term for mesuring how big a motor is, it means c- cubic i- inches d- displacment, 5.8 liters is a v-8 while a 2. 4 is a 4 silender(kind of obviuse) the old 4 cylinders  worked on a 4 stroke aprerating system, the first stroke   the intake opens the and the fuel is sucked in to the clynder the second stroke is the compression stroke were the valve closes and the piston moves up and the fuel is compressed, on the third stroike, the power stroke were the spark plug makes a electric spark and it pushes the piston back down, on the last stroke, the exoust stroke the exoust valve opens and the gasses are push out of the cylender, this process repeats itsself over and over, the downforce on a indy cara t 150 mph  theroreticly is enough to drive upside down   on a bridge / whatever and still out perform a sports car. down force is air pushing on body panels/ wings ect on a full frame car that has a roll bar is only alowed 1 removable bar that is located across the door on the diriver side. the shoulder bar on a roll cage must be at shoulder level or 4 inches down for it to be legal. how a motor works- ok i dont know all of this but i know most of it- ok the starter is activated by the key, and sparks the spark plug,  and fuel is injetid in to the motor,and the piston moves down,wich moves the crankshaft rod wich  moves a chain that is connected to the cam shaft, when the cam shaft turns it pushis against the lifters, wich push aganst the push rods, the push rods push against the rocher amrms, the rocker arms are ona  spring that pushis it back down in the spring there is a rod, or the vavle  that pushes down, and it lets fuel in to the motor, then the piston moves up and the fuel compressed then it  is lit, then it pushes the piston back down, then exoust vavle is opened with the same process, this contiues over and over, the connection rod turns the transmission, and the transmission turn the driveshaft with gears. technickly a car can run without vavle covers, the only thing that would happen is oil spilling all over the place. in the 60-80 people made vavle covers that were clear so that you could see the rockers move up and down. cam shafts have 16 lobes on them for a v8, they half of them are shaped difrently, 8 for exoust,8 for fuel. there are 2 difrent types of push rods, rollers a smooth, rollers have a small ball on the end of it alowing for less friction but are less durable, smooth tips are a solid rod, more friction but more durible. performace rocker arms have no  better qalitys than a stock chevy motor rocker arms. if you ever go to a drag race, and look at the pro mods, at the begging of a race you can see a stream of white stuff coming out from just below the windshield, this is the purging vavle for nitrus, contary to though this is not nitrous oxide, it is air that is pushed out of the nitrous lines.a supercharger is the same as a blower, the supercharger is just a name for a blower that is belt drivin. a good difrence to tell a biger cubic inch for a smaller hemi, is the smaller cu in  has sparkplug wires traveling from left to right and the biger cubic inched moters go from right to left. nitro powered funnycars/dragsters get more power from there engenes if they hook up, or otherwise get more tracktion, becouse the engine reacts to pressure  in such a way as to at idol the car may produce 8000, while if it where pulling against somthing and not moveing it would be producing about 8500, this is due to the fact that nitro methane has such qualities in that if you threw a match in a puddle of it, it wouldnt explode, but if you put a drop on the ground, and hit it with the hammer it will explode, therefor while inside the cylinder of the engine as there is more pressure applied to the piston to move the more pressure put on the fuel, making it explode with more force than when jsut ingnited with a spark plug. the average modern nitro funny car or dragster produces about 8000 horsepower at the back wheels, its kind of like this, emagine a production honda sedan, then amagine the power that tat pruduces times 80 or in other words emagine it with 80 engines and still weigh about the same that it did before, harley earl was the chief of desine at gm's automotive desine area, harley earl desined classics like many of the caddilacs, but he also made many concept cars as well, he rode in the first lesabre, it was his daily driver and it was a hit but was never produced in mass, he also made the firebird 1, firebird 2, and firebird 3, they where all futuristic cars powerd by a gas turbine engine, the lesbre that harley earl desined had 2 gas tanks, one stored regular gas and the other alcohal, when the car was at idol it just used regular gas but when you went at high speeds the alcohal kicked in and gave in a extra boost of power, john delorian was chief of staff and desine for the GTO project, later he was cought in a 24 million dallar drug skandle sting and was sentinced to jail, the only years of the chevy vega that was produced as a cosworth was 1974-1977, there is 2 types of lifters, rollers and regular, rollers have a axle on the end of them that has a metal wheel on it, as is rools along the cam shaft it moves up and down, a regular lifter or a solid lifter, is just a lifter that dosend have a rolling  ball on the end, one way to tell if the motor is a solid lifter or rolling lifter without looking at the lifters is to  look at the camshaft, if the lobes on it have very steep inclines on them its a solid lifter, if the lobes are more rounded then it is a roller. on most alcohal funnycars and dragsters if where the push rod conects to the rocker arm lacks luberication for just a moment during a run the end of the push rod turns blue from the heat, and if it gets to hot, it could break. i have alot more but i think this is enough for now
