Another '67 GTO Project
 

This one looks better to start with, but the asking price reflects that.
Has some nice options too... Rally I's, Rally Gauges, Safe-T-Track, Reverb, Headrests.
Seller mentions possible HO car, is that a boxed upper rear control arm I see?

Big project.

That’s not ‘67 heads or timing chain cover.
Possible later engine.

Seller should pull the PHS before stating it could be an HO...aren't they all, until proven not.
The '67 I rebuilt 12 years ago came with the 335 HP engine, 4 speed and 3.55 posi and had the reinforced upper control arms. Obviously, someone could have put them on, but if so, they had been on there a LOOOONG time and were as rusty as the rest of the bomb.

Yes, even if the original engine gone, that will make a difference. Really, that's interesting!

Good eye! I did notice the timing cover tab being the later type. Now I see it also has the '68 & up valley pan (PCV in front).
