I will be replacing the 383 in my challenger with my new 451, so Im wondering how much money I can recoup from the 383. The engine is a 68 or 69 HP block (out of a roadrunner or bee) and is the same engine that is my avatar. It was rebuilt in 1977 and has only seen around 20k miles since then, it was never abused and runs strong. I put a timing chain and all new gaskets in it about 4 years ago and before I put it up for sell I will probably put all new gaskets in it again to see how everything looks. The engine has a forged crank and 906 heads, for performance it also has a hemigrind purpleshaft, matching springs, and a 383 torker intake. The engine has a bunch of chrome like the timing cover, distributor hold-down, valley pan ends, dipstick, and some accessory bracets. I would also be including almost everything else that goes on the engine including the waterpump, brackets and pulleys (alternator, crank, and waterpump), an alternator, a set of aluminum valve covers, an original 71 383 carb, and some e-body headers. Basically the only thing this engine would need would be an ignition system and a better carb. The engine should be perfect for someone looking to upgrade from a /6 or needs a 383HP for their roadrunner or bee....so the real question is, whats it worth?
