well i finally got the thing driveable. i am still lacking a front driveshaft (that is why i am bearly flexing in the pic, i had to creep up in 2wheel) the tranny pan has a slight leak, i need to replace a rear wheel seal but other then that its rockin. the 351 has about 55 psi when cold and about 25-30 hot. the motor runs cool, not sure how cool because i dont have a temp gauge but i am running a large electric fan, a rigid fan off the water pump, and a 160 degree thermostat. its a four core aluminum radiator that is the the same size as an explorer radiator. i am running the tranny cooler in the radiator and an aftermarket one. there are still quite a few little things i have to pick at to get right but its basically done...
