Hi All,

Currently, my truck has the original good running 305 v6 with about 93k miles on it. The transmission is the 3-speed on the floor. I'm wanting to swap out the old motor and transmission but having a tough time figuring out what swap to go with. I have around $10K as a budget. this will be my daily driver during the spring to fall. looking for about 300-400hp and converting it to automatic. what is a good reliable option to go with for my budget?
