What are your plans?

I want to obviously end up with a v8 with either car but keeping the costs in mind. Which car can you find the most parts for when restoring and or upgrading and which one would be the easiest to work on?


I'd go with the newer car and the one that already has the V8. How is the rust and over condition of the car?

The car is in good condition rust very minimal lots of new parts, needs new headliner . Thanks for your input

Also needs a floor pan on drivers side but shouldn't be hard to replace


The reason I say the V8, because you can drop another motor in it easily, and not have to update the PCM or trans, brakes and rear end, etc.

the v8 car will already have motor mounts etc for a v8. the 305 is a crap motor. I would get the v8 car and swap in a 350. you will have to change the computer no matter what motor you swap in.
