I am looking for my 340 that came out of my 71 Challenger. Vin#jh23h1b209943. I know the engine was worked on in Sarasota Fl. at Sarasota Cylinder Head Service, 4682 Ashton Rd.in Sarasota Fla. by the owner, T. Workman. The engine was totaly rebuilt by the invoice that came with the car. The car then went to Russellville, Ky around 1983 to 85 from the Vehicle tax notice and insurance papers that also came with the car. Do not know if engine was still in the car. If anybody knows of the engine please contact me, the car really misses it. shatar4@comcast.net
