Right. You have to choose what FEAD you want/how you want to space everything out. This is why truck intake is better

So no way to adapt it? Or a different throttle body?

Maybe it was a LC9 water pump then.

Default Engine is in!

Question at the end.

I got the engine, tranny and transfer case in. Driveshafts and starter also. Driver's side accessory drive and throttle body done. For posterity's sake, here's what didn't work: bellhousing is a different bolt pattern. DBC throttle body will not fit with the truck water pump. I used the ict rotation adapter and the lt4 angle adapter to make it work. That holley DBC plate did not fit my cables so I modified it. Otherwise most everything worked. The ls3 oil pressure sensor will not connect to my harness. I have an oil pressure sender in the old lm7? Single wire. Do I need to swap the sensor to get my Guage to work?

Is there any way to adapt the sensor to my one wire plug and have it run my Gauge?

Just swap the sensor. Why is this even a question?

Just curious how it works. And the engine is in so not a lot of room to get at the sensor.

Sensor is somewhat tricky but not too bad to remove. You need a special socket from Lisle. I have it and will look for P/N for you. I have removed it a few times now.

Answer is no to previous question.
