Cool deal...I kept this 71 340 since 1977 when I totaled a real 340 RT challenger. I brought the short block into a spare bedroom with a 2 wheel dolly in 1984 when I got my house. I have a basement but the bedroom was easier to use. It sat in this exact spot until 2007 when I needed it and it got put in my 74 car with the edlebrock heads. Still running today. I kept the forged crank and replaced the heavy factory hi compression pistons with KB 243 10.5-1 hyper pistons. Kept my compression up and was able to use a lighter piston on stock rods. I did not re balance, factory balance job and it runs great.
