if op is serious about any kind of real record these are the sorts of approaches that will make or break it.
My bug is already ‘sorta’ light so I’ve been playing with cutting ounces here and there. Here’s a couple examples of steel motor mounts I remade in titanium.

Do you have a true ram air setup that forces cool air in the engine? In the tune, make sure you zero out IAT timing correction up to about 150f so it’s not pulling timing too low. You could play with EOIT in the tune also. (End of injection timing). Sometimes there’s a little power to be found there too but I’m not sure if it’ll help with a stock cam. You need the highest stall (that you can tolerate) with a high multiplication factor. Thinner oil. Thinner diff fluid. Lower the car a little if it’s not lowered. Less drag. Battery in the trunk if it’s not there yet. Lighter rotors if you can afford it. Make sure the pads do not drag.
There is only so much you can do to stay within the prescribed "rules". Many things are a waste of time on their own; put together, it might be worth just enough to put you/keep you at #1. Sounds like that's what the OP is aiming for, hence nothing is a waste of time if it adds to the bottom line, even just a little, when the rules are tight. The weight savings alone is worth something in this case. Remember, don't just look for ONE place to lose 100 pounds, look for 100 places to lose 1 pound.
Look into @Darth_V8r @HioSSilver @big_hammer and a few others who've gone down this road. Try searching the dyno section.

Anyone have thoughts on lightweight under drive pulleys like Innovators West? Any pick up over a heavier SLP/Powerbond etc?
everything adds up. Rotating weight makes more difference than static weight.

For sure. Looking for experience of one over the other. One of the above, might have been Hio, can't remember now, said they went to a Innovators west and belt going form crank to alternator and picked up consistent 1.5mph in 1/4. I'm not sure if that's over stock or over a different pulley aka SLP etc. Haven't found much other info

that is a complete waste of time. I deleted my power steering, removed the heaving steering gear box (third gen) and put a tubular K member on the car only to lose 1/10 of a second in the 1/4. Total waste of time, money and effort. Plus I ruined the car because it drove like **** with manual steering. I stopped driving it because of that. Power steering takes maybe 1hp of parasitic drag because you aren’t turning in the drag strip.
How’d the OP run an 11 second 1/4 mile? Is it “stock” like the “pro stocks?”
*Edit*
Dang, 11 second bolt-ons.. Is the recipe leaving at redline and being able to have tires that’ll hold it? There’s a pretty big spread between the slower and faster bolt-on cars (would 13’s to 11’s be fair to say?). At any rate an 11 some odd 1/4 mile is insane fast for a 300 and some odd rear horse car that’s not exactly go-kart sized.

Trying to push my car with bolt ons only…. What is the No limit bolt ons? Stock internal 346 Ls1
What Im currently thinking but open for input:
1 7/8 wrapped longtube headers
True duals/dumps
Mamo ported 102mm fast intake/TB
Chrs1313 pro stock ram air
SLP under drive pulley
Meziere electric water pump
GZ Motorsports vacuum pump
Proper tune
NGK 55
MSD wires
Up for consideration/discussion:
- aftermarket/upgraded coils
- e85
other…?

I've seen a bunch of suggestions here and read some of your other threads about weight reduction but I haven't seen anyone mention aluminum exhaust..you mentioned using true duals dumped at axle..I'd suggest doing an aluminum Y pipe with 4" single and an aluminum muffler dumped before the axle..look up Herfurth aluminum racing mufflers.

Or even replacing points/condenser ignition with a solid state (like Pertronix) ignition module.
So yeah, ignition components don't make more power, just regain that power lost with weak ignitions.
BTW, LS OEM ignitions (coils and wires) are proven pretty good. Nothing aftermarket has shown conclusive improvement.

This sounds more sound than the 11 second bolt-on pass.

Stock ignition coils are just fine. People have ran them to 1400+ whp... I would say your best bet is to just find as much weight to take out as you can. K member, replace the carpet and padding with ozite. Gut the hvac out of it. Ditch the airbags and factory wheel... Lightweight steering column. Lighter wheels obviously. Aerospace or tbm brakes. Lighter door cards made out of abs or something. Lexan hatch window, lexan door windows..

FYI I kept stock wires and went TR6 plugs as my tuner preferred them bc they gave him more room to safely play apparently.
I also bit the unnecessary bullet and put a heat shield under my intake.
Things I’m still kicking around:
-E85
-Crank scraper
-Changing under drive pulley for a lighter version like Innnovators West
-Some kind of crossover for exhaust, right now it’s just dumped after headers
