L92/4L80e swap onto 07 TBSS
I'm kinda new to this side. Normally on lS1tech side. Well I finally got tired of being "stock....ish". I've been having a pair of L92s in my garage and undecided on what direction I wanted to take the trailblazer SS. Here's my plans and would appreciate any feedback or opinions. these are the parts that I already have.
09 L92 6.2, with LS3 intake valves.
224/228 .581/.588 114
4L80E with 3200 stall
Kooks LTs
C6 oil pan swap
I'm undecided on what springs to run. Either a beehive PAC 1218 spring set or is a .600/.625 double spring needed? Reason I'm using that cam is because I want a mild cam and already have it. I might consider selling it but is the bigger duration split really worth it? Also might consider porting the intake. Btw it's a 2WD. Any advice on what else I should look into? Thanks.

I am new to the LS world myself. As I am swapping an LS into my OBS.
I have hit the search button and even posted a few questions that went unanswered.
I did come across a thread where a Poster was actually poked at for asking about swapping in a Corvette oil pan with a baffled pan for oil starvation issues on the twisties.
Why are you changing to a car oil pan? Clearance issues?
I have the opportunity to get an Oil Pan from a 00 Corvette C5 LS1
I am currently have L92 heads on the motor. I was informed that the TBSS UIM will not work, needed to upgrade to a truck intake manifold.
"L92's have square intake ports as opposed to catherderal ports on the 317/243/799's. You will need to run a different intake manifold like one from the newer escalades/denali's/vette's with the 6.2L or go aftermarket. L92 heads also use different rocker arms on the intake valves so you wont be able to reuse your old ones."

alot of truck guys dont like the L92 heads cause they seriously lack low end power.
But since you already have all those parts, get some springs and throw it together and see how you like it.. Dont those already come with 4.10s?
