Re: Love my new engine/trans;hate the MPG!
The 383 can be a low rpm torque motor. Look up that GM HT383. It makes 345 or so HP and 440ish TQ. Peaks at lower RPM. That's what you buy for efficiency. The motor you have is better for acceleration.

Re: Love my new engine/trans;hate the MPG!
Trying clear things up here. There are nonelectricaly operated lockup convertor setups for some 700r4's. Please see the link below. From what the OP has said he has one of these. No vacuum switch required.

Re: Love my new engine/trans;hate the MPG!
Thank you HO455! This is very helpful as this is the early style 700r4 that I have which does fully lockup but without any electrical switching required.
