I recently purchased a pulsating tank style block heater for my truck. I'm running a 4.9l straight six with a holley 4 bbl and a offy dual plane intake. Currently I have a heated carburetor spacer plate and a heater plate under the intake manifold. I'm wondering where the best place to tie in this block heater would be. I purchased this style because I liked the idea of bein able to start my truck and have my vents blow warm air right away, because it gets cold here in Nebraska. My first instinct was to have the heater output go to the heater core, manifold plate, carburetor plate and then back to the engine, but the more I thought about it the more indecision I had. Let's hear your opinions. I wanna tackle it this weekend.

 

There is a plug in the block just above and near the front of the starter. I plumb into the block there for the heater inlet and the outlet plumbs into the heater hose returning to the water pump. The heater is mounted on the firewall. I use the Kat's 1000w circulating tank heater. Nebraska winters gave me my introduction to block heaters.

 

Are you speaking of one of the freezer plugs? So the fluid leaves the heater unit and goes up to the core and then back down towards the water pump?

 

No, it's not a freeze plug. It is a block drain hole with a threaded plug in it.

 

Cool I appreciate your input. Whereabouts in brasky are/ were you?

 

Auburn for 4 years and another 4 in the Bridgeport, Broadwater and Bayard areas.

 

It went below zero 64 times up here last winter! Im becoming a heat guru for my atv and the dent lately!
