Is there anything that can be done other than weight reduction to improve my street mpg?
My limited knowledge brings me to believe that higher performance = better fuel efficiency, but I could be wrong. Would something that is proven to give hp gains like an Underdrive Pulley help with fuel efficiency?
I can start a different thread if need be.
But what are your thoughts?

A underdrive pulley will help, rebuilding the engine will help.
I think the 6-speed manual trans helps Highway mileage. After rebuilding my 'S' engine I easily get 30 MPG at highway cruising speeds (70-75 mph)

The 6 speed swap was said to be pretty hard. Might have to avoid that
Thanks for confirming the UDP. Sounds like that and weight reduction is the key!

Hey buddy! I’ve been trying to be more active (outdoor activities) and stay off the internet. I don’t check in daily, anymore.
Glad to see you back around here!

I think I miss directed alot of anger(ya think?). Again truly sorry to all! P.S. If I had a white car it would look like pws' very nice

Takes a big man, nicecar.
Glad you're sticking around. I think everyone's input is valuable here, even PW's, even if one's input contradicts another's. It just gives the reader/OP more information to go on and make their own decision.

My new favorite member. (at least for the rest of today, haha)
It takes alot to say "whoa nelly.... I might've (whatever... I won't belabor, you all know what I'm saying here)"
and funny thing; I don't even remember the episode you're referring to here. If I was rude then, my apologies now. I'd love to tell ya I'm just misunderstood, and that it was surely just me trying to be funny / sarcastic. But the truth is; I'm sometimes a dick. (that's why I always try to forgive other people who are sometimes too. hahaha.) If I were never going to say anything wrong or offensive, I'd need to change my name to Trump.

Thanks, Maytag. I know you did that just for me! hahaha!
But you know you shouldn't bring up politics, because someone on here will get mad at you!
