hi, im putting a tpi motor in my 86 t/a, i removed the heater,i removed the a/c,and im not passing the coolant through the throttle body,,so just to double check to be sure, is all i need,the 2 big main hoses from lower rad to pump,and upper rad to thermostat neck?? can i just plugg/delete the exits on the lower front of the intake manifold and everything else?

 

and also,what thermostat should i use?? remember,i have no heater,not gonna drive this car in winter,want performance only!

 

Just plug up the ports on the manifold with an allen plug.

Since you have a TPI, you don't want to go any lower than 180 due to the computer and all it's fussiness.

 

thanks,thats what il use

 

If you have iron block and heads you will b just fine with a 160 t-stat.
I have been running one in my aluminum headed 89 350(well bigger now) formula since 92 and its been just fine. Also use a cooler fan temp switch or chip that'll kick the fan on earlier..

 

i have an iron block,aluminum heads,im gonna have a chip done so anything can be done at this point,
