you cant do a 350sb conversion for the price to fix the head gasket on a 3.0
I did!!!A head gasket job is at least $1200.00.Most of it in labor.I did my sbc for around $1100.00 give or take.Everything is a lot less complex as the 3.0.No vacuum lines ,$200.00 gasket set,etc,etc,etc...
I had a friend who blew two sets of head gaskets within 2 yrs of each other.Most of the stuff I used I refurbished which saved alot of money.
