i just bought a car from my friend he says it is a 71 elcamino and it has a V8. he says that it is like the motor they use nascar. I want to make it a little faster so we took of the filter and muffler. yesterday i showed my friends how fast it is so i steped all the way on the gas and drove around the field. it realy sounds like the rase car but i can spin the tires better. all around the hole field it will dig up all the dirt. after about one hour hot steam came out of the hood. my friend says it does that because it makes so much power. how long does it take for your rase car to make steem? it makes a clunk noise when it runs but goes away when i push all the way down on the gas then it just shakes like the race cars my friend says the clunk is from the big pistons he put in it and it is ok. i am going to rase my friends today and let you know when i beet them.
