actually your wrong with a few of those 
Nothing that actually makes a difference in power tho.
well he did forget that its tuned for a big shot and has naws, sooo that makes a tiny difference in powers bwwaaaaahahahaha
I don’t even know what’s in my car lol
I’m down to do a dig race in the rain/dirt/snow 
no. I have 7.425 pushrods, texas speed rumber catback, stock air lid, 04 ls1 etc.
and NOT rlms tuned.
That’s a lot of pre-load on the lifters, definitely surprised you have 7.425’s. TSP rumbler is the same idea as the SLP loud mouth, and your air lid is SLP blackwing which was an optional part over the regular one.
I have bassani mufflers in my rumbler and my air lid is not a black wing. Its just a smooth lid. Blackwings say SLP on them and “blackwing” in the lower right corner. Mine does say either. Not to mention it would say it on my door jam on the SLP upgrades. Doesnt say it.
Then it’s not a stock lid.
then wtffff it is JD. All I know is its smooth and it fits like shit. Doesnt even seal on the damn sides.
I know what the look like lol.
Mine isnt either one.
I will post a pic
I had one just like you describe, I ended up selling it. Direct-flo was the brand.
pre nitrous and right after I bought the car.
Whisper lid.
whatever it is, its junk. Doesnt fit for shittt
well its a POS for $140 LOL
They ALL fit like garbage, I have the SLP aftermarket lid… fucking TRASH.
if it fits like shit, its def far from stock and some cheap shit…not being a dick here just sayn
No worries! jdaniels the LSx encyclopedia had no trouble identifying the lid.
