This means VIN = 4.8 from what you're sayin. IDK what VIN 8 letter designation refers to on a 4.8. No, the VIN will never tell u if a motor was swapped. The 4.8 / 5.3/ 6L all have same external dimensions. Therefore, do some digging. Then tell us what u find.

Movin on, if u know 4.8 was originally what it came w/., & whoever they is (dealer, private owner), swapped in a 5.3, how else would it have got there? No offense, but what are u tryin to accomplish w/. this thread?

I certainly don't know everything, & never claim to, nor will I. We're all tryin to help u here, but are u messing w/. us or what?

Sounds familiar. OP, do that then.
Be nice Newbie Mod MOD. :nunchuk1: Give a some power & he thinks he's King ****.

Or throw it on the dyno and tell us what it makes, that would be easy enough to decide what it is.
How's EFI or HPT know that? I thought it's tied thru VIN? Maybe not tho. Cause if a 6L is swapped in place of a 4.8, what will tuning software say motor size is? That sounds mo betta.
Verification trumps dyno.

I don't understand how hard it is just to say if the VIN contains a 'T' or a 'V'

If it is indeed a stock 5.3, then you have not been lied to. The tune obviously has been changed if you were doing 120mph, but that doesn't mean it can't be a stock 5.3

How do you know you were over 120mph? the speedo only goes to 100.

I have had a very good LOL at this thread and well I do think my IQ has dropped some reading your first statement.

Every one is giving you very good information on what to do and how to go about doing it.

Verification trumps dyno.
If you scan a File doesn't it tell you the configuration of an engine? There's a couple tables in the config tables that have the type of engine, displacement, etc... I would think that the tune had to of been changed to reflect a new motor should that be the case.

Am I right or wrong?
