Well tbh the 90's weren't good at all for muscle cars... and that P.O.S is gonna take some hard work and hard cash to make it worth a dam... so unless ur getting a killer deal on it I think i would pass, but that is my opinion and my car tech knowledge is only a little higher than average.
On a side note: Do u think a 75 Ford Ranger with a rusted body, but a big block that runs fine is worth restoring?
