Rebuilding a 74 Duster - Kinda...

I voted 360. You cant call your mopar a muscle car with a /6 unless you put a ton of money into it.. a /6 car is a "classic car" lol. A 360 will give you power with fuel economy, then again you don't build muscle cars for fuel economy so I would go with a stroker or even big block. THERE'S NO REPLACEMENT FOR DISPLACEMENT You will spend the same amount building the 360 or a big black as you will building a 318/340... so might as well get your bang for your buck.. as for rear end and tranny.. to each their own.. You could even build a muscle car with a modern twist like a few guys on here. Good Luck with your build and Keep us posted!
