Replace, Upgrade or Aftermarket

Here's my leaky proportioning valve. If you know , this can be bad for ones health. Plan on replacing brake lines but also the valve itself. Is the 4th gen valve an upgrade since I came from drums to 4 disc? Should I just get a stock replacement for a 92 rs or z28? Or should I just go aftermarket?

Happy forth.

Memories from the past. Unfortunately they’re all gone and I own a 5th gen now.

Low oil pressure after running dry. Bad aftermarket sensor or engine damage?

Hey guys, need some advice on my 1993 z28. On a recent drive, my oil pressure switch ruptured and dumped all the oil out. The engine died on a railroad crossing—it would crank but wouldn't start. When it finally did start, it started knocking. Checked the dipstick and it was bone dry.
Towed it home, added 4.2 quarts of oil (total capacity is 4.5 quarts), and the knocking stopped. I replaced the sensor, and it’s no longer leaking, but now my oil pressure sits dangerously low at idle (almost 0). It goes up when I rev it, but not as high as it used to.
I’m looking at two possibilities here:
The aftermarket sensor is poorly calibrated, everything is fine, and I got lucky.

The sensor is accurate, meaning the bearings/lifters are shot and the clearances opened up, so it can't build pressure anymore.

What do you think? What should my next steps be?

1998 Trans Am part out

I have a 1998 firebird im parting out, somebody did an LT1 swap (LT1 is from a 1995 Trans Am/ Formula/ Camaro Z28) has aluminum heads, was told it has a stall in it so it shifts at higher than normal RPMs, it has been sitting for a year but it fires right up, rear end is nice and quiet, we have neighborhood driven the car and runs like a champ, again this is a FULL PART OUT - Location - LINDEN TENNESSEE (Can ship most parts but anything big like the front bumper or hood is pick up only)

98 to 02 front clip in grey primer, with an aftermarket WS6 hood which fits surprisingly well, headlight assemblies are present but have no covers to them, includes impact bar with foam, fog lights and marker lights, this is perfect if youre doing a 93 to 97 front end swap

Honeycomb tailights (Also have a Trans Am filler panel for extra)

Trans Am hatch with spoiler

Trans am rear bumper cover

Power doors with new window motors

Hard top headliner with a small cut in the back by the hatch, would probably never notice it (Sun visor not included)

Grey 98 to 02 center console

Have quite a bit of ebony and grey interior plastics

Anything else you might need, just let me know and I'll check if I have it, I do NOT however have any ground effects except for a W68 package that came on base firebirds

Overheating after New Optispark Install

Hi all, could use some advice here. 1995 Firebird LT1 V8 had optispark replaced, along with new water pump. Shop has told me it solved the bucking and jerking motions it was having, but engine is overheating at idle. The tech said he thinks it’s an air bubble that builds at idle then when on pedal it circulates/dissipates.

Tech said only thing he can think of is head gasket repair or new motor swap.

Any thoughts/advice on what I should suggest they look into deeper before these actions?

How much would you sell for?

I’m looking to have kids soon and need something that is more practical..

I have a 95 firebird trans am, lt1 and 4l60e with about 91k miles. Paint is rough in some spots, no overt rust. 4th picture is from the hood, 5th is rear hatch. I bought it around 80k miles 6 years ago.

Upgraded umi rear lca, torque arm, and subframe connectors. Rims were powdercoated black and have tires with less than 2k miles on em. Also corbeau front seats. Also stock center console was changed for a 98-02 one.

Other than that pretty stock. No engine work. Over the last 6 years i’ve gotten new brake pads and rotors all around, new power steering rack. No t top leaks.

Thanks for everyones help.

Wiring Harness

PFA: Recently re-wired my 74 with an American Autowire kit and wasn’t thrilled with the kit being it was $1k. Now I need to re-wire this 5.3 swapped (Holley Terminator setup) 1980 I just bought and I’m debating on what harness to get. A “plug and play” harness for this car is even worse at $1400. So at this point I’m leaning universal since I’m modifying the harness anyways, and deleting things like heat and ac. So, should I just get a cheap Amazon one and call it a day, or spend the money for a Painless or American autowire kit?

Serpentine Belt Replacement Recommendations for Stock LS1?

I recently bought a 2000 Trans Am WS6, fully stock, from the original owner with 18.5k miles. It's currently at just over 19k. I'm looking to replace both belts (accessory drive and A/C) since the rubber is original and 26 years old at this point.

I've looked around and see different opinions on Duralast, Gates, Gator, Dayco, etc. Does anyone have experience with the best option for a fully stock LS1 setup? I've seen some say the Gates can make a bit more noise as it's slightly longer.

Also, would anyone recommend doing the tensioner and idle pulley while I'm doing it?

Part numbers or links would be appreciated. Thanks!
