hey guys. i was thinking of doing a small project with my corolla 74. its been in the garage locked up for the last 10 years. has not seen daylight since the summer of 1999 
it was my grandfather's car. and has only been driven 50,000kms. he was the first owner, and bought it brand new in 1974.
am thinking of:
1) overhauling this current 1300 litre engine
or
2) put some other new engine
but cant decide what would be better. so do tell me which engines are a good option for this car???
also, which is the best mechanic to get engine overhaul for this engine in rawalpindi/islamabad?? name and phone numbers would be appreciated.
thanks
