Re: Z28 Camaro a good Drifter?
A completely stock 240 with a nice LSD (clutch type) will have no problems sliding. It is best to learn with less power anyway. I first started out with a KA-Turbo car making like 220whp. My current car was completely stock when I got it and I learned a lot more control and technique with the stock KA in it. Now I have a stock SR and I can go faster - other then being able to go faster there really isn't much difference between the SR and KA - not for someone starting out.
A Z28 Camaro will make a great drag car, get something with IRS for drifting. It just so happens 240s are a decent weight, have a nicely designed suspension and are easy to slide. Do yourself a favor and use that.
Buy a LSD, some coilovers, rear camber and toe arms, and tension rods - get an alignment, and buy an extra set of wheels and you'll be set for starting to drift in a 240. (That is ideally as well, you don't NEED the coilovers or suspension arms, it just lets you set the suspension up right.)
Also - do yourself another favor and attend some Auto-Xs, they'll let you get used to the limits of the car.
