It's badged a GTX.. Dissapointed when I looked at the car..
Motor had been swapped because of a 'bad knock' according to the original R.O..
Currently has the 3100 apparently out of a Lumina.. I've bought a 3400 LI & TB from a Monte Carlo, & 3100 UI from a '03 Malibu (so it says 3100)..
From there not really sure to go after.. Always open to suggestions..
