Ive got a Offy intake, can someone post pics of how they plumbed it to work? i dont have a heater core in the vehicle.

Your engine should have a pipe plug near the thermostat and another near or on the water pump. Run a hose from the thermostat outlet to the intake and run another hose from the other intake fitting to the water pump. I don't think which hose goes where should matter much.

So it just is put inline with the waterpump bypas
s to the thermostat housing? ok that makes sense.

Offy's need to be sealed before use with water. Atleast with the 230-250-292 manifolds. The plug is only staked and setup for exhaust heat. I prefer to see the plugs sealed by welding. Tom

Tom Langdon has a page under Tech Tips illustrating this, even with a diagram

good luck,
