The time has come to pick a motor and I need help from you experts. I've been out of the hot rod game for 20 years, and I'm at the point in my project to pick a motor. The drive train components already selected are 200R4 trans, 12 bolt with 3.73 posi, all the typical stuff, Hotchiks rear control arms, 2 inch drop spindles and disc brakes up front etc.. I'm not looking for an 11 second quarter mile, but I don't want a slow poke either. I've thought about everything from a ZZ4 small block to the 502 crates. My mind and check book are open , so please help me decide. Edlebrock makes a 410 hp crate based on the ZZ4. I'm confused by all the choices. I don't want something I have to tune every weekend. Help.
