TVS2300 and a couple of other things

Been a long time, at least a few years but I'd figure why not and make a thread on the 07, which used to be my DD for about 4 years but hasn't been for the last 2, which is nice (bombing around in the 05 tahoe with an LQ9 and 65e from an esky). What isn't nice is what driving the TBSS a couple of times and I really do mean a couple of times in Virginia salt bomb land does to things, really amazing, not a big deal tho, really.

Ya so relocated from VA with no garage to AL with a 2 car garage, FINALLY

Basically I'm still kinda gettin the garage set up, but going from where the TBSS was and still is in terms of mods from NOV 2019 (last time I drove it further than around the block)

79k stock LS2
4L70E RPM Lvl 6, bought it second hand, about 85k on it now (has never missed a beat, a nice surprise)
Yank 3k stall
Volant CAI
various tunes of my work and others
Belltech shocks, not lowered
normal brake stuff
Kooks + catted Y pipe (need to get the uncatted one for an FI setup, evidently)
PCM Brake duct trans cooler
Aeroforce Gauge (great tool)

Going to-
TVS2300, stock pulley
PCM Tempest Cam (didn't want to go too crazy, but the dyno charts look good for a 218 cam imo), plus not going crazy on lift
Melling pump, all the normal stuff like pushrods and all that everyone does on these things
Bigger FI Connection Injectors
Bigger fuel pump
gauges from Speedhut (they have some that are really close to the TBSS cluster style)
FSR rad+efans
PCM trans cooler spal fan kit
PCM of NC 2 Bar SD Tune
PCM Catch can (I'm curious to see how much oil the manifold pukes)
Yella Terra Ultra LW 1.7s
LC32 crossmember
LS2 C6 TB (maybe, not sure yet, have two tho if anyone needs one. They both work fine, just remember to change the scalar in the tune etc)

As far as fluids, Amsoil 10-40 premium, Redline D6 in the trans, prolly won't change, been workin fine so far, (knock on wood)-

Things I'm still contemplating, and would look for input from the knowledge-laden folks here-
I'm concerned about the 6 rib not being sufficient seems like it only really holds for a stock ls2 plus maggie? I'm not sure exactly, probably a factor of how hard you beat on it and how well things are aligned etc etc. THoughts?

That also brings up the alternator, OEM as everyone prolly knows has a clutch- finding a shop that will upgrade the TBSS DR44(G ?) to say 185 and keep the clutch has been unfruitful, but I haven't spent an inordinate amount of time looking, just a few emails etc, nothing solid yet.

If an 8 rib is required, I assume you can just pin the other side of the crank (I believe the IW pulley setups use two dowel pins), that may sound dumb but I'm just makin sure-

Ya, its a stock short block but I read that 5-6 lbs is fine and 8lbs is knockin on deaths door, which is fair.

I'm also considering some trick flow 225 CNC heads, haven't purchased them yet, but I think if I go heads that will require an 8 rib setup. What do you think of this? Besides the 'get a forged short block'', I'm lookin at it, really on the fence, I'm not going to pulley up this hog tbh. But ya that's what people say, right lol
Some pics. Its a work in progress, I'm tryin to build the garage and take advantage of the cool weather, I need to POR 15 all this damn rust (isn't that bad tho), gotta get the headers recoated, install Atomic fab motor mounts, rebuild the entire front end (lower arms, upper arms, everything is gettin replaced).Gotta re-do the wheels, but I think I'm gonna have them professionally refinished to fix the little rash bites on em etc. Also need to buy some SS brake lines from clarksville fasteners. Need new spark plugs and wires still, also-

SO MUCH TO DO but this will be fun. Ya lemme know what you people think about this6/8rib, alternator, heads, etc,etc. Or anything in general, thanks

Yup Gates RPM, that's it.

Do you remember if your converter was shimmed already? Its easy to check the gap using a 1/8" drill bit placed between the flexplate and converter mount lugs. But too far into the trans you risk cracking the pump, too far out and you risk stripping the teeth off the pump gear.

When I was doing my research on the 31.5" spring conversion, I was told to only get the rubber isolators for the top of the spring that contacts the frame perch, that the bottom of the spring on the axle didn't matter. I just didn't like the fact of the metal on metal of the spring and axle perch, that's why I went with isolators on top and bottom.
No shims when i zapped the TC bolts out, so no shims between the pad and the flexplate.
what I kinda of dont understand, and correct me if I’m wrong because I probably am, but if the reference point is the flexplate, and you need no more than 3/16 but no less than 3/32 from the flexplate to the TC pad, then doesnt that totally ignore whats going on with the depth on the pump?All pumps and converters can’t all be the same on dimensions, idk maybe they are?
idk maybe the logic is all pumps and cases are the same but the variation is in the converter pad and flexplate? I

I understand the concept of spline engagement and pump stuff etc but i guess im wondering why the ref point isnt the pump/trans. Eh whatever miller time
I'm no expert but the transmission bellhousing/trans body never changes, its the converter that changes. When the converter manufacturer builds them, they have to weld the 2 halves of the converters together and that's where the difference in depths come from.
that makes sense.
well, do it once and do it right, goin with sending the block out to go to 402/3, thanks again burnit53. thats a good dude there in vegas. 5 week turnaround from the time he gets the block, so I can't afford not to go with that! The short block is gonna be back before the headers and y pipe return from Jet Hot, so that's cool. i mean why stop now, 10% over IW 8 rib, 4l80, meth, ahhhh stop the madness

Did you ask Jason about head studs?
I haven't yet but I will definitely be bringing that up. studs all around! I'll prolly give him a holler tomorrow, very knowledgeable guy, as you know.! ya this is gonna be awesome, I'm already thinking about an 8 rib kit, I like the ati for looks only, eh i mean whats another 1200 bucks at this point, eff it. I'll prolly call ATI tomorrow also, hopefully we can piece something together. I've been savin up funds and parts for this build, its nice to actually have time and space to actually get some sh!t done the way I want for once lol. MURICA
I also saw this, maybe it will work on the TBSS alt, maybe not. I'm thinking holden LS3 or L99 cars have some things in common with the LS2, maybe right- Maybe this 8-rib alt clutch pulley will work on the TBSS alt. I'm a big fan of the overrun clutch for some reason, it just makes sense but it seems like nobody has one on their 8 rib setups. obviously this may not work lol, eh worth a few bucks if it lines up and prevents belt stress dealing with the alternator, worth 80 bucks or whatever. the second catch, besides probably not having the proper thread pitch/type, is coming from Australia. arrrgh

Nice build. Just wrapped up a 2 year TVS2300 build on my 06.
I have a IW 8 rib balancer I am not going to use if you go that route. I ended up running the 10% overdriven unit on my SS and have a new stock diameter 7.25 balancer on the shelf.
Thanks guys for the feedback- Ok lemme chew on that IW pulley idea, thank you sir
Drove to Wilkes Performance near B-Ham and dropped of the 243s for a full workover, evidently Mr. Wilkes was doing this for a while for some big name shops (cnc heads etc) before some went super big time corporate or whatever. Not goin with the trick flows for now due to lead times (forever), so these should be fine for the 402/x. Evidently there are some people pulling tf genx 225s off for these, ok, we’ll see how they do!! Im pumped either way. Yah, 2.055 and 1.60, why not. It might work out pretty well with 10lbs

Fuel filler hose at the tank. That was more azz pain than it should have been but hey, all good. Waiting for the lingenfelter pump assy. It was 450 bucks, right, but it does have
-new filter
-new pressure sensor
-new level sensor/sender
-new regulator

and obv new walbro 450 or TI or whoever bought walbro, idk

So overall, worth it to replace 14/15 year old stuff before the madness begins. Also tore out the spare tire assembly, don't need that anyways right. Watch; I'll get a effin flat tire first time out LMAO damn you, murphy, damn you-

Merry XMas mofos!
