I got a lot of stuff done on the car this weekend. I finished ALL of the wiring except installing the torque converter lockout relay and an engine to body ground. I just placed an order for some fittings for the steam vent and engine oil priming setup. If all goes well next weekend the car will be running. Still lots to do before I can drive it, but it should be running!!

Yes it is! I finished the exhaust, torque converter lockup relay and a few other items tonight. At the current pace it won't be much longer!!!
I still need to come up with a pre-engine start-up checklist just to make sure I haven't overlooked anything.

I am in the home stretch now. Before I fire it up I need to install the intake, CAI, plugs, wires, prime engine oil pump, bleed brakes, install PCV catch can and add: oil, trans fluid & coolant.
I am having a heck of a time finding a location to mount the Mike Norris PCV catch can. The thing is enormous. Anyone have any suggestions as to where I should, or shouldn't mount it?
It's a mess, but here is a pic of the engine.

Good news! Early last week my neighbor and I finally fired up the LS2! THe motor sounds incredible! Everything went well and the motor isn't giving off any OBDII codes. However, the tachometer is dead. I need to look into why. It's getting power, the tach signal wire is hooked up and I have it set it to 4 cylinder mode.
I will post a start up video later! In order to drive it I need to align the front end, install the seats and do some safety checks as the car has been apart for almost 6 years.

What a great thread. I'm fairly new to the site; but am finally at the stage in my build to start thinking engine/trans. I'm going with the same engine trans/combo and also got it through Travis. I don't have it in hands yet, but have only good things to say about Travis just from talking with him, as you've experienced. Just some really good info here. Will have to go through this a few times.

Travis is a car enthusiast, located near Indianapolis, IN, that got into selling engine/trans pullouts a few years ago. You will be hard pressed to find a better person to deal with. He even recently open shop on the side to do LS swap, plus he has a guy that can mod harnesses, or made one from scratch.
Thanks. The speedomter should be fine, as I have it hooked up to the speedo wire from the ECM. It is electric and I will just have to calibrate it once I am on the road..

Not much time for the car this weekend, but I did get the front end aligned, started cutting the carpet and added a pull up resistor to the tach signal and it is registering now. Of course I do have a few other issues.
Any suggestions would be appreciated.
- Alternator output is 11.6V - New corvette alternator, all wiring is new and secure plus I have a 470 ohm resistor inline on the red wire going to the alt plug. I have plenty of grounds also, 2 2/0 cable going from the engine to the body. Anyone have any suggestions.
- Lower radiator hose started leak - After 10-15 minutes of idling the lower radiator hose started dripping at both hose ends. When looking at the hose it looked like it was bulging since the thermostat hadn't open. This is the first time I have had any leaks. TO stop this should I drill a couple of 1/16" or 1?8" bypass hole in the thermostat to relieve pressure?
- Tachometer reading fluttering below 1,000 rpms. - I add a pull up resistor to boost the tach signal, but when engine rpm goes under a 1,000, the tach need is not steady (flutters). For the pulll up resistor circuit I used ignition power to a 4.7K ohm resistor tied into the tach signal. Anyone have any suggestions.

Hmmmm, in my notes I have "add a 1K ohm pull-up resistor" to the tachometer signal. I have not done it yet so I really don't know.

When I originally got my harness from SSP Wiring, they did not label any of the wires like they said they would, and they never replied to my emails about hooking up the alternator exciter wire. I was so enamored with the fact I read I needed a 470 ohm resistor I did not check to see that they had already done this......
On the plus side I did come across a great thread showing how corvette, f-body and truck alternators should be wired, https://ls1tech.com/forums/conversio...ml#post7748845

Not sure if you added a steam vent line to your system (can't tell by engine pics)... That will eliminate the "bulging due to trapped air". (line attached to my upper rad hose)
This might be your prob if you don't have one...
