First off can I hurt the engine by running the stock 19# injectors with the 350 chip [the fuel pressure is up a little to try compensate] . The a/f gauge at idle shows lean and when it warms up or I give it gas it stays right in the middle[green], I did take it for one cruise about 15-20 miles. The guy I bought the engine from said to change the oil after the first drive and I was thinking of doing new spark plugs too. The only thing that doesn't match the chip[TPI Parts stock 89corvette prom w/deletes] is the injectors and knock sensor. I have a couple scanner programs to monitor the ecm with and nothing is looking to bad, I guess. Although I'm no pro when it comes to datalogging or whatever. Thanx for any and all info .

definately need the knock sensors AND the injectors swapped over.

You might be able to get by with the 19# injectors with a good reprogram and increased fuel pressure, but there is no good way to program around the knock sensor.

If you have trouble removing the original sensor, you can mount another one like this:

That looks pretty good, might have to give it a try. Do you need the ESC box to match the 350 knock sensor? As mentioned I did drive it and didn't really get on the throttle but felt very strong. I didn't go past 4000RPM on it, new engine. Also If I feel under the block off plate there is a little oil leak. Should oil be flowing through there?

Yes, you need to get the right ESC module to go with the new knock sensor. They're a matched set for each engine size. It's perfectly normal to have some motor oil behind the fuel pump block off plate. Just get a new gasket and smear a small layer of rtv on both sides, and re-install the plate. Before modifying your plate for a new knock sensor, you ought to at least try to remove the original one from the side of the block and replace it with the correct one. I've never had too much trouble getting them out. Just make sure to drain your cooling system before you remove it so you don't get an anti-freeze shower! It'll still leak some out, but not near as much with the system drained. I usually put a little liquid thread sealant on the threads of the sensor before installing it also.
