Carb'd LS1 Questions I'm getting closer to actually swapping my LS1 (just ordered the adapter plates and headers yesterday) so I'm trying to get everything I need to get started and have a few questions I haven't been able to find the answers to.
1. I've heard electric fans from a 4th gen f-body can be used. What do I need to make them work?
2. Most 2nd gen owners have clearance issues with the a/c compressor (using fbody acc.). If I decide to notch the k-member can I use the stock 4th gen fbody a/c compressor even though I'm going carb or do I have to use an aftermarket compressor?
3. Do I use the 2nd gen or 4th gen condensor?
Sorry if any of these are dumb questions, but this is my first ever car project and this site and nastyz28 have been my only sources of information.

1. You need to wire them up so they come on with a switch, with a designated temperature setup or a combination of both, mine are on a switch so i can turn them on at the track for quicker cooling.
2. Notching it is required to use the stock GM LS AC compressor, it will work with a LS that is carbed if you wire it in.
3. there are retro kits out there that i am sure will help you decide what condenser to use, i dont have AC on my car.

Thanks guys. Getting really excited to start pulling the old motor out and getting the new one in. My wife is using the 70 as her DD this week while her truck gets fixed, so it's getting a nice last run before it gets parked for a while. Should be starting the work soon and should have a build thread started within the next couple of months so be prepared for more newb questions

Would it be possible/reasonable to wire the second fan to come on when I turn on the a/c?

New question, this time about gauges.
I want to get these gauges from summit so that I can monitor my oil pressure and water temp until I can afford some nice aftermarket gauges and a new gauge panel. What do I need to make just these 2 gauges work, and would I be better off with electrical gauges or will the mechanical be fine for now?
