i have a 1965 coupe de ville with a 429. the engine is currently making entirely too much noise but the car is too nice to get rid of it is my new little bundle of joy so i bought a 1976 500 engine with the 4oo trans and the driveshaft it is going to be rebuilt but the builder dosnt do swaps. now comes the problem i now really want this engine in this car but dont know if it will fit does anyone know if it should bolt right in or is this a project where i got way in over my head. any info would help because i am stumped.
