if you have an auto trans don't bother thinking about trying to make more horse power, as the trans will just suck up the extra horses.. besides...
you might want some good struts.., the ride is probably pretty soft with those miles on it...
also good brand of brakes,, but for adding horsepower.. I say don't bother...
if you have a good engine you are getting ready to drop in, you could have the head redone and new pistons, rings, bearings...
since it's already there...
if it's 5 speed... put a new clutch in before you drop it in...
you may end up needed some new halfshafts when you drop it in... as the old ones maybe worn out too...
as you can see it will cost you a few dollars jsut to keep it stock but a nice car..
it would be a shame to drop the motor in only to have these parts go bad soon after you put it back together..
IMHO
