Looking at 69 mustang w/351 not running tho...

i was wondering what some obvious reasons why a 351 would not run. lets say the nothing majorly wrong/blown motor. the thing is, is that i dont know if it cranks...until saturday that is. im going to look at this 69- sportsroof, 351, 3speed for $1500. even not running thats a good deal i think.

i was thinking
no spark
bad gas
seized (guess that is major now isnt it)
heads are jacked up (kinda major too)
and i dont know.

and ideas? things to check for?

thanx

yea thats what i figured. a 69 stang with a 351 and a stick is gettin pretty hard to find. and the guy doesnt know if its a mach or not. if its a mach its wayyy worth it.
