Big Block 516 Heads On A 68 383 GTS Dart? - 11/01/09 03:48 AM
I have a 68 383 Dart GTS convertible. The assembly date on the original engine is 9/20. The engine has 516 heads on it, not 906 heads as I would expect. I know the 67 383 engines in Darts used the 516 heads. The engine has been rebuilt at some time in it's life. Is it possible that these heads are original to this engine, and were left over parts that were put on from the factory? Anyone seen this before? Also the numbers matching block is not stamped HP, nor is the block in my 67 GTS Dart (assumed to be original - cast and build dates are just prior to vehicle assembly date). Anyone seen this before?
