No problem check out your private message and I detailed for you what I did and cost for each Mod and what I want to do also. This site is very helpful for all Impala owners to share information. :smile:My impala looks exactly like yours only its an 08. I am unfortunatly not really mechaniclly inclined but Im a quick study:smile: Please let me know what you have done mod wise and what you wish list would be less super or turbocharging the car. Thanks again Mark
but isnt the tranny the hardened version of the silverado 1500 so it should be able to take more horses and torque since ours were dumbed down for the fuel mgmt systemthere is a 2008 impala ss v8 like ours, from texas... he is running 13.5 in quarter mile almost stock.. some small mods like drag tires, larger downpipe exhaust/no cat,think also k&n air cleaner set up,etc... if you get to much more power , you can count on tranny going out !! rkvette
No, that would be a 4L65e, yours is (IIRC) still just the 4t65eHD that was in the 05 impSS... they cant take much more than 300 whp w/o "improvements"but isnt the tranny the hardened version of the silverado 1500 so it should be able to take more horses and torque since ours were dumbed down for the fuel mgmt system

pretty much, like i said the stocker is good for ~300who, so you have some room to play a bit. Most LSx boltons can be "adapted" to fit your car, but most wont bolt right on...so by improvements you mean total tranny sway for someting beefier. kinda hard since we are fwd isnt it.
