Well todays drive with some little changes in the computer helped. Made some adjustments to the injector cutoff. Helps the low end a bunch. Still not great but its something. However it did not come without some hiccups.
First I am already fuel starving at 18 miles after putting 5 gallons of gas in. So looks like the next stop is the gas station. Gauge is moving around enough to hit empty in the corners so this should be an easy fix.
However number two could be a problem. On a easy pull at 4000rpm the oil pressure on the gauge started to drop. However when I let off it seemed to jump up. So next plan is to put my mechanical gauge on the engine and run it. Hopefully its just a sensor problem. Hopefully its not an oil pump problem. Bearings looked ok when the engine was out. Everything was torqued back to spec. Oil is still near the full line and no leaks yet.

Well, oil pressure problems have showed up. So looks like the engine has to come back out. Anything over 3000 rpm the oil pressure drops to 20psi. So it's parked again. I'm actually in no mood to pull the engine. So time to take insurance back off any let it continue to rust away.

Don't give up on it yet, you got real lucky with the deeply discounted 383 regardless of issues, you are clearly being tested for your loyalty by the LT1 gods ....there is light at the end of the tunnel! My car was a wrecked pile rotting away under a carport for over 3 years before it rose from the ashes like the proverbial Pheonix and now is busting asses and taking names daily It does take quite a bit of patience, dedication, and downright stubborness to stick with a LT1 build for sure! Once you get that 383 running right, you'll realize all the headaches and trouble was worth it!

That sucks man, I know the feeling of working for hours on a car only to discover more problems I wonder if the oil pressure issues existed before the crash or if a nasty hit like that could have tweaked the oil pump or pickup somehow? I take it you put the mechanical gauge on it to confirm the issue?

As for the oil pickup. Looked fine compared to my other one. I was so close to installing my newish gm oil pump. Should have maybe it would have helped the problem. Who knows, but at this point its 10 hours of work that I don't want to do.
Ill try to keep moral up. But its fading fast. First car love is even gone. I would miss it in 10 years but for now I would let it go an just take some cash.

Well the car is still on the back burner. I am moving in a month, plus my daily driver miata needs some work in both the suspension and the failing 5spd has a bad bearing somewhere. I have had a spare transmission in the garage for the past year and a half. I knew it was getting bad so nothing like a $100 transmission. Miatas are stupid cheap to run and repair. I was really hoping that the Fireturd would be running so I can take a few days with the miata.
Been doing some research and getting nowhere on the issue. So i guess the engine will be coming out. My other oil pump will be going in. I guess new bearings will also be on order. I have friends willing to help but scheduling makes it into September before it will happen. I know I have helped my buddy put everything from his crashed mustang into his new mustang (yeah I know its a mustang). But hopefully moral will go up by then. Still willing to sell it as its the biggest money pit ever. Maybe one day it will be worth it.

Wow...7 engines? If you're in the money pit this deep already, what more do you have to lose pulling the engine an 8th time? Take your time and pay attention to the details. Just remember you have quadruple the HP of the miata just waiting there to be finally unleashed!

Yeah the fun of crappy machine shops and crappy parts. You think everything is right and then get screwed again. The horsepower will be fun but the huge cam is not. Tuning is needed but cam surge is bad under 2000rpm. I think I have grown up. I really don't care for the car. It's been a pain in the butt. Buddy was joking the other day. He has had loads of these cars. Only the Pontiac Firebirds have been a pain. Must me something about them. We are dedicated but still I have a few cars that have caught my eye. Something practical. I think it's time to save for a while and buy a corvette in the future.

Well played with it some. I think we have the problem. Looks like the thrust bearing is shot. Max end play is .008 of an inch. I am seeing somewhere around .036 of an inch. At least that is what I am getting off the balancer. Either way the engine has to come out of the car again. Hello new bearings and a new oil pump. If this does not fix it the car will be parted out. I will not be pulling the engine again. This will be the last time or I am may just burn it to the ground.

How much do you want to sell the engine for?
