How much money do you have? I hope you have more than you can use. First off a 302 Chevy engine is very rare and expensive. Second is you could do at least as well(power and money wise) with a Mopar engine. You would need to change motor mounts, transmission, and have a custom drive shaft made. And that's just the start. While your car may be collectible, a Chevy 302 is worth more to me and many others than your car.
