    Default 280 engine into 240 with carbs - what to do with this tube?

    I'm finally back on my 240z resurrection project and have stripped the header and exhaust manifolds off the '75 280 engine I have.

    I never had an engine in the 240z that I bought to compare but I'm not sure where this tube is going to connect once the engine is in place. I am putting SU carbs on the engine and do not plan to run the water heating through the carbs since I live in CA where it is never cold enough to worry about heating the carbs.

    I have included a picture of the tube that sticks out of the side of the engine and attached to the intake manifold that I took off.

    Also, I found out that I only have 1 of the 2 brackets that bolts to the block of the engine and attaches it to the motor mounts. If anyone in the San Jose, CA area has a spare one of these brackets Id love to get it from you so that can drop the engine in and start hooking things up.

    That tube is for the PCV valve, on the FI models the hose went to the bottom of the intake manifold, and with the SU's the hose will hook up to the PCV valve on the balance tube.

    try black dragon auto or motorsport .com, they'll probably have the engine mount that you need
