94 Z28 looking for some input Hi all long time reader first time poster, 94 Z28 LT1 been a long term project gone thru the woes of transmission and opti spark putting it back together now, with new pan gasket and MSD opti instead of a cheap one and thanks to everyone that posted on here save me a ton on what to look for and stay away from.
I have some questions and looking for input, this thing is a beast, someone loved this Camaro a lot back in its prime, have been in a few the same year and none of them roar like this dam thing does I am convinced this is a 383 stroker, it has 165k on the speedo doesn't burn a drop of oil, has BBK headers, throttle body and cold air intake,aluminum heads now comes where I need the input.
1) I had the 4l60E upgrade ( got 6 months drive time before opti spark went ) done to the trans 2 years ago yes its been waiting that long for me to finish the opti spark and timing chain, pan gasket debacle so it has the 5 pinion planetary and upgrades, my concern is I go down the freeway at 80 mph and I am running about 1700 rpm dam things gets mileage a prius dreams about, I have seen 35-38 mpg, am I hurting the transmission ? I believe it has the stock rear end and drawing a blank on on the ratio at the moment but at that low an rpm am I pumping enough fluid thru the trans? and should I swap out to a different ratio and if so which one?
2) At 1700 rpm going 80 down the freeway is that motor generating enough oil pressure? Not a lot of load at 1700 rpm but curious if this is normal ?
3) A/C delete curious if it was worth it ?, I know its actually more expensive to get it back up and running but with the motor in this car its not like its going to kill me on fuel economy.

I knew I was going to get some doubters on this which is why I posted the question, I know it sounds like I am full of it but at 55-60 mph I have to kick the dam thing out of overdrive or it starts lugging bad around 1200 rpm and I am scratching my head on this too
Yeah that’s pretty common. My 395.3L LT6 with corvette pistons and fuel rail covers just clocked 42.87 mpg’s last week. I have it geared to a 1:1 where I can do 88mph at 850rpm’s. Welcome to the club!
As far as oil pressure is concerned I have an oil pressure booster that runs directly off the brakes! Bloody expensive, but worth it!
PS- It’s for sail, too. It’s a one-of-a-kind Super Special Camero. Has 130,000 on the clock.
$27,500 frim
no tire kickers
much have cash in hand for test drive!
