I'm restoring/modifying a 64 Convertible SS. I'm trying to select a crate motor and I've been thinking ZZ4 SB, but a lot of you tout Big Blocks. My question is can a convertible 64 body and chassis handle the torque of a BB or will it twist into a pretzel? And the second question is which BB crate motor? I'm not looking for an all out drag car, just enough power that I can terrorize the neighbors, and every car that pulls up next to me at an intersection. Other drivetrain components already purchased are: 12 bolt w/3.73 posi, and a 200R4 w/2500 stall.
