Hello from East Texas!

hi everyone! I have a 58 Apache, small window, step side. It will be getting a new chassis from No Limit Engineering soon. I’ve been trying to decide what engine, transmission, gear ratio to put in it. Been think small block with automatic and 3.73 gear. But what about 4.11 gears? Maybe a big block with 5 speed transmission. I just want a fun hot rod for the street with some neck snapping power. Thanks for your advise and opinions
