Assuming you mean 400 fwhp, then full exhaust and bolts ons should do it

A nice proven setup is

Peak speed ported fast 92
Ls6 MAF descreened
90 mm lid
1-7/8 headers
Speed engineering x pipe duals
Tune

This will get you into the 365-370 rwhp range through an M6

You can get over 400 rwhp with bolt ons but it takes more work

Whats the list?

Your list above is great but to get 30-40 more.. out of bolt ons..? (I feel like i'm missing something obvious). I know it would be something accessory drive related like underdrive/electric water pump/no belt at all lol. But what else am I missing here.

EWP is one. Manual Steering. If you have a manual transmission a lighter clutch and smaller diameter clutch, going to fast102 vs fast92. From air filter to throttle, make that whole tract 4†and smooth. UDP.

This one can be contentious. In the small block days we used to consider higher ratio rockers bolt on. Now people see it as a poor-man cam, although the rockers cost more than the cam. Go figure. Even roller tip vs stock is helpful, because stock rocker ratio varies. You gain low lift duration with rollers.

That is probably not everything, but that will get you a good bit more. Most people will not do that list though, because a cam is cheaper than a EWP or a manual steering rack, etc.

Carbon Fiber Driveshaft, Pricey but effective.
Lighter Ring & Pinion & Diff, if available, lighter wheels &
Tires. (Soon to find out if micro-polish trans &
Ring & Pinion is worth anything)

I got 430+ rwhp out of a bolt on ls1. It's an expensive way to get the power but then when you do go to a cam and heads you're making lots of power

Forgot that one. Knew there was something. Vacuum pump too.

But when you add all that up, most will say just go heads/cam. There is something nice about a motor that has not been opened up though. Never quite seem as tight as from the factory

I'd consider heads to be bolt on.

Definition of bolt on can be a gray area for sure.

Superchargers bolt on right?

Like Darth mentioned in the small block Chevy days rockers would usually be viewed as a bolt on. That's the way I think of bolt on 's.

Occasionally, someone would argue if engine oil touched and lubricated the part it's not really a bolt on its an internal engine Mod. In that view rockers aren't really bolt on.

If it involves more than removing the valve covers and oil touches then it's well beyond what I think of as a bolt on. Heads or supercharger are definitely not a bolt on to my way of thinking.

Do the older LS1's with the bigger factory cam tend to be better for bolt on hp than the latter 01-02 cars?

Lol. Nitrous kits bolt right on too!!

I tend to include rockers as bolt on. Intake, exhaust, accessories, etc.

As a guy with an older ls1 with full bolt ons and 243s I wonder this all the time.

400 wheel is doable but not easy.

To be bolt-ons only the vehicle must be stock internals and NA. 98-00 cars do have a bigger stock cam but the 01-02 cars offset it with better 241 heads. Some 00 cars have both the bigger cam and 241s.

Rockers are the grey area. Personally, I don't care either way but it needs to be general consensus. That's the only reason I haven't done them. I'm sure some the the guys on the fast list have them but they don't allow them anymore which is a disadvantage.

400 wheel is doable in an LS2 or LS3.

LS1, i can't see it unless it's a generous dyno.

The earlier cam. Which is worth 5-8 rwhp over the later LQ4 cam

LT1 and old 5.0 guys considered rockers bolt ons. Some guys don't. Not really a big deal. They're easy to install and so help a little
