6.2l LS start up on run stand.

We are LS swapping a 6.2l into a 1966 GTO restomod. This is the third time starting it up, found a coolant leak and an oil leak on the first two attempts.
This one has a Sloppy Mechanics cam and a FiTech ultimate efi kit. It should give this classic car some pep with great fuel economy.
Happy hot rodding folks.
