Ultimate ALL OUT bolt-ons?? 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…?

Only bolt-ons. Clearly heads/cam etc can push power. I’m looking for options that fall into “stock internal” as I’m working on a purpose built car to go 10s stock internal.
It’s an auto and I’m aware of the stall etc, but I’m making sure I’m not overlooking any power adders that would fall into the “stock internal” category as described above. The engine can’t be opened up, or at least can’t be upgraded in any way.

Not really. It’s a just a “bragging rights” thing. My 6spd is the fastest stock internal 6spd ever at 11.1 and want to push my auto faster as well. “Stock internal” is a class I suppose but only one made up online
Lol no power adders.
this is probably true, but the stock internal guys are a pretty stand up crowd overall and I’ve gone fast myself and know what’s done to the cars so believe most of the cars to be real/not cheating. At this point there’s also nothing to gain. Back in the day certain shops might have benefited from have certain records but no one cares anymore on these cars 😂
back on topic… does anyone have any other thoughts? Experience with e85 on stockish motor? I plan to run a short belt routed so it doesn’t turn the power steering as well.

With stock cam you’re pretty limited. Throw it on a dyno so you know where peak power is and get gears and converter that holds you right in that rpm range the whole pass.
Use the shortest(lightest) tire that will hook. This will tie into your gears and converter calcs.
lightweight everything including oils
I’m surprised there’s any real unopened ls1s left.

plenty of unopened cars although I’m sure quite a few less then 10-15 years ago😂
Everyone forgets how stout the original Ls1 a were imo. All obsessed with turbo 5.3s 🥴

Idk how you add power without modifying the motor....maybe a ssra ram air induction box. Free up HP with 25% under drive pulley, or delete power steering and AC. Thinner felpro head gasket? Electric water pump.

I don’t know much about these. Any experience? I’m open to different fuels. Not going nitro etc but something like this 🤷🏻♂️

To answer yes, of course we are removing weight.

10bolt can hold more then most will let on. They won’t hold long term with sticky tires but can do just fine for a couple times a year track trip and then street driving with normal tires.
My car has a stock rear with 3.42 gear out of a 6speed. I have an extra waiting if it breaks 🤞🏻

For example, no one has answered about e85 or other higher octane fuels yet. Would love any input with someone that has experience/knowledge. Same thing with aftermarket coils/truck coils etc

q16 is an oxygenated fuel. it will make more power than c16. m1 also will make more power but im not sure which will make more. q16 is a gasoline so it wont require the large fuel flow that m1 will.
your own stipulation of untouched heads and stock cam basically limit what you can do. your only options are what intake and exhaust gets bolted on.
if you said 'stock displacement' or 'stock lift camshaft' then you can start getting creative but unopened engine is an unopened engine.
