It has 5 total 1 tach water, volt, oil temp and press. I was thinking I was going to remove the oil press I don't think I will need it. No the block is bare. I don't even know if the gauges work I might have to buy all new ones. It has procomp liq. filled ones in there now.

I think all the Olds people will agree here. If could have only one gauge on an Olds. Thats the one! Search "Olds" in this forum for more info. :p

HAHAHAHAHA. Listen to this. Do not remove the oil pressure gauge.

HAHAHAHAHA. Listen to this. Do not remove the oil pressure gauge.
I'll go a step further, put in a Pro lite, big bright one, right in your face. AND install a mechanical oil pressure gauge, back by the motor is OK, that you can see from the drivers seat, to verify the electrical is accurate............MP
PS: Don't let those "Olds" stories scare you, with the right stuff they are teriffic engines and make tons of torque. Just don't try to RPM it like a chevy.
