Thanks, guys. New springs definitely, new rearend, maybe. My 350 has incredible low-end torque. Most of my driving is in OD, and Iwould like the RPMs at 65-70 to be in the 2000-2300 range. I know the acceleration will be un-stellar, but am more concerned with fuel economy. BTW, I'm running a 4GC square bore w/ manual choke.
