i bought my Datsun 2 years ago, it was $250 and ran sometimes it ran sometimes. I drove it every now and then, then 6 months ago i pulled it out again and swapped a Weber on it drove it around and then started a knock and almost home and blew threw a rod through the oil pan. I want to keep it alive and i haven't pulled the motor yet to see the damage and i want to motor swap it and i want to stand out and put an i6 L motor in it and not sure with cutting and such will it "bolt in"
