Hey guys, I'm new to the forum and hope I am posting this in the right spot. I'm looking at buying a '79 Z-28 over here in Eastern Washington. The body is all right, the interior is decent at best and the T-tops seem to be in decent shape but he said they leak a little. The engine and tranny are the reason I'm interested in the car. The guys says it has a 383 stroker motor, with aftermarket headers, cam, Holly carb & aluminum heads in it that he and a friend built, along with a Turbo 400 tranny, 3.73 gears and posi rear end. I'm really interested in the car and am taking it for a test drive on Saturday. I would like to know what I should check to verify that this car is mechanically sound and also how I can verify that it is bored out to a 383 without pulling the head off to measure. The guy is asking $3000 for it. Any opinions on whether this car is worth what he is asking and what all I should do to verify that this thing will run decent for me?
