Hey Fellas,Alright, I've lagged enough and I've just about got all my parts on order. I've got a few concerns and questions that I was hoping you guys could help me with. Looking at the picture below. The seller mounted the temperature sending unit at the rear of the manifold  . Right next to it is a ductaped port and I assume that's the (full?) vaccum port?  The next picture shows two masked ports that I'm not really sure what the functions are. I assume the one covered by the spark plug wires is for my heater hose? And I have no idea what the hole closest to the intake manifold opening does. Any ideas fellas?  Thanks in advance. Erik ------------------

Erik I'd say the rear one is for an auto trans modulator vac source.The front one under the wires looks like the heater hose.And the other front one I dont have any idea.SCOOP ------------------

Scoop's da man  Both pipe threaded bungs in the intake runners are in fact full-bore vaccum ports. DO cap them with the appropriate pipe fittings, can't tell what size with the tape covering them but they'd be either 1/4" or 3/8" pipe plugs. The one under the spark plug wires could be heater hose or sending unit, your choice... but there should be one more female pipe fitting in the water passageway just to the driver's side of the distributor, that's where the water temp sender is usually located  [This message has been edited by V8 Thumper (edited 09-09-2002).]

Thanks for the replies fellas. The temperature sender is unusually located at the back for some reason. No more ports near the distributor.Are any temp senders OK to use? I've got an autometer phantom water temp gauge and the sender I have for it is a lot smaller in pip size compared to the ports on the intake. The guy I bought it from didn't have any adapters or bigger senders. Is it ok to use the sender in the intake currently? Thanks again. Erik ------------------

The type of sending unit is not as important as it being accurate. The location of the sending unit is ok if water is going through that passage. On my intake there is no water traveling through the back of the manifold it is blocked off, just the front.------------------

Not necessarily. Senders are nothing more than a progressive switch that the gage reads as ohms or resistance. That's why senders are different for gagues vs. idiot lights. If you've still got your old sender, I'd use it. There's no telling (without a ohmmeter/multimeter) how that 'new' sender will work with your gagues. It might be close, then again, maybe not

hmm, well the old motor is using the stock OEM gauges and when this new motor will be put in, the entire instrument cluster will be replaced by a full electronic Autometer phantom gauge set (sorry, forgot to mention that). The sender that came with the Autometer water temp gauge is fairly small in width. I was hoping I could use the sender that is installed but then again, I wouldn't want to damage the gauge.Erik ------------------

Erik go to any big hardware store and get an insert that fits both the intake and sender.I used one for my Auto meter gauges.SCOOP ------------------
