Default Planning out LS1 build - am I missing anything?

Planning ahead an LS1 build based around the MS3 cam, here is my part list, am I missing anything?

Yank SS3600 converter,
Summit 3.73 gears,
SLP airbox kit,
PaceSetter longtube headers,
MS3 cam 113LSA,
LS7 lifters,
TSP Upgraded rockers,
7.4" chromoly rods,
TSP 660 dual springs,
LS2 timing chain,
Melling high volume oil pump,
Bosch Green Giant 42lb injectors,
also assembly lube and new valve cover gaskets.

I am pretty sure I have it all covered but I want to double check before I pull the trigger on it. TIA!

My list I'm starting is all motor related but I also added a new rear cover, and SacCity barbell to what you have.

Planning ahead an LS1 build based around the MS3 cam, here is my part list, am I missing anything?

Yank SS3600 converter, - more converter
Summit 3.73 gears, - more gear
SLP airbox kit,
PaceSetter longtube headers,
MS3 cam 113LSA,
LS7 lifters, - go with johnson drop ins
TSP Upgraded rockers,
7.4" chromoly rods, - you need to measure pushrod length when the cam is installed before you can order
TSP 660 dual springs,
LS2 timing chain, - katech c5r chain
Melling high volume oil pump, - high pressure not high volume
Bosch Green Giant 42lb injectors, - more efficient injectors like ls3/ls7
also assembly lube and new valve cover gaskets.

I am pretty sure I have it all covered but I want to double check before I pull the trigger on it. TIA!

Regarding the converter and gears, would I be fine with a 3800 stall and 4.10s? I'm looking for decent drivability as this will also be my daily driver most likely.

if it were mine id go with a yank ss 4000 and motive 3.90s that would give you the best performance. dont forget a trans cooler

Okay so I have made the following edits so far:
Katech C5-R chain,
LS3 injectors,
Melling high pressure oil pump

I looked into the Johnson lifters and they're a bit more expensive than I am wanting, and the only 3.90 gears I could find on Summit had bad reviews so I'll do some more looking on that.

Is this a good converter ? This one is decent spec and won't screw my wallet. https://www.summitracing.com/parts/ape-49455/overview/

Will 4000 stall with 3.73s drive fine?

Needs compression. Didn't see that in your list

no way you would even notice the differance in 3.73 and 3.90 with a 4000 stall you will be fine

Don't cheap out on lifters, I did the first time and wrecked my cam. They might seem expensive, but it's worth it. "Do it right or do it twice."

The list as-is won't equate to a strong running combo. MS3 is a max effort LS1 cam. Unless you want a max effort LS1 car I would put a smaller more appropriate cam in there. But assuming you want a more max effort combo, you will need more compression and more converter to take advantage of the cam. I would do something like a Yank SS4000 or PT4000 for the converter. While you have the heads off for the lifter swap I'd run a .040" Cometic gasket to get the quench at a more ideal level while also giving a small compression bump. If heads aren't in the budget then I would mill the ones you have to bump the compression further. Since the Johnsons are more than you want to spend, check out the Morel drop in lifters. For the oil pump I'd pick up a stock LS6 pump and port it yourself, videos on youtube show how and it's easy. Don't order pushrods until you appropriately measure. If on a budget, the LS2 chain on stock gears (if in good shape) will work fine, tons of people go that route although there's better options available.

EDIT: Just saw you said this will be your daily driver most likely. If that will be the case, this could be all wrong. An MS3 car with big converter is not daily driver friendly for most. Have you owned a cammed car before? Are you ok with the potential of cam surge and bucking in a daily? Are you ok with running high cruising RPMs until the converter locks in a daily? Are you ok smelling the overlap of that cam in a daily? Are you ok with 10 mpg for a daily? The converter will help tremedously with taming the overlap of that cam from a driveability standpoint but you can still expect surging while cruising. Just things to ask yourself first. I once daily drove one of these cars with gears, a big converter and a cam with a lot of overlap. It was cool at the time when I was 20 years old. Now, 10 years later, I'd rather poke my eye ***** out then deal with that. If your answers are yes then go for it. Just trying to help you make an informed decision.

I would take heed of Stealth Formula's advice re: the ms3.
For some reason a lot of newbies buying their first cam start at about 237/242 @.050 duration and I'm not sure they always know what they are getting themselves in for going that big.
The cam in my ls1 has +16 degrees of overlap and I drive it everyday so when I refer to 'newbies dropping big cams in ls1s' I think I can include myself in that group lol.
If you have been in cars with similar setups then carry on as you were, alternatively I'd consider something more like a 228R - if you want a choppy idle just get it ground with 108-110 degrees of lobe separation.

You can get a 228r on a 112 LSA. If you want a cool choppy idle make your adaptive spark correction super aggressive

my cams pretty close to an ms3, and the car runs and drives great its all in the tuning. I didnt lose any mileage over the stock ls6 cam i had. ive been pulling 18-20 avg mixed driving with the ac on with 4.30 gears and a 6 speed. My friend had a full weight 02 z28 with the same cam, 3.42, 3600 yank and that pulled 18 avg and the tune wasnt 100%
