1965 Dodge Dart Charger

I´ll have to check the sender unit in the gas tank.
And then I have a 3,91 gear for the 8 3/4, I hope to find some time to replace the 2,76 that is in the rear for the moment.
But the first thing to do is to check that the leak from between the block and the head is fixed.
Thing is, I´ve had the head removed and checked that it is within the tolerence but I don´t have the guts to test it because I see alot of work in front of me if its still leaking, lol.
