hey i was wondering if anyone knew what i needed and what size to fit for the holes in the intake.

im hoping the front ones are 1/2" i have a pipe plug for one side of the thermostat, and what is it called for the other side, hose barb? i need it for my heater hose.

and what about in the back?

 

Unless you need to thread sensors in them or something, plug the holes into the coolant ports at 3 corners and put a hose barb into the other one.

 

ok so just a hose barb for the front heater hose, and plug every other holes.

thanks.

 

anyone know what size i need for pipe plugs on this intake?

the front 2 on each side of the thermostat 1/2" pip plugs fit perfect, what about the back 2 on each, and the one up to behind the carburetor, 1/2" seems to be too big.

 

The vacuum port behind the carb is probably 3/8 NPT, the coolant parts at the rear should also be 1/2 NPT.

 

see there are different measurements.

the front 2 are 1/2" pipe plugs.

the 1/2" pipe plugs are too big, and 3/8" are too small.

 

The plugs in the rear are 3/8 pipe.
