he doesn't come online anymore, its been over a year now
Oh yea ik but I don't plan on trading it in but next time I buy a impala it's gonna be the 2015 chevy ss v8
thats not a impala, its a chevy SS, nothing to do with a impala.
if you going to trade in your car why bother doing that huge list of modification you have planned? seem pointless.
But they're completely different cars.... one is v8 rwd with optional manual trans, the other is v6 fwd and auto only. And they don't even look the same either....
No they are 2 completely different things.. and way more then just timing will be need to be changed in your tune for a cam
idk about 3.5l but 3.8l does not need new pushrods, stock ones are fine
