Hey Guys need your help! I have a 454 block that I'm rebuilding for my 68 and need some help figuring out which way to go with it. I'm not sure what the differences are between a 454 and a 427 torque, highend,street manners, ect. I can go either way with it I'm just not sure what would work best for me. I'm not looking for a racer just a good strong street machine thats reliable and fun to drive. M-20 behind it with 3:73 grears. Thanks for the help.
