Building 69 383 for my 69 dart.

For me the car was an original 383 so that is what I want to build.....just looking for a stock look with reasonable cost and hidden performance. This is not a race car and original exhaust manifolds will be used I will go to an aluminum intake dual plane and aluminum water pump (painting all original engine color) loosing some weight. so no sense in considering huge cams etc, just a good performer to cruise
