NYCMAX0723

I've been lurking on this forum for a while since last year when I bought my 95 gxe. I absorbed a lot of useful info from here. But now I've bought my second maxima a 97 se 5speed. It's been rough going for this car it has a salvage title. It's got 104k but runs like it's got on 300k. I got it for a good price so thought it was worth it. But now I'm at the point where I have a head gasket problem and it's on it's way out. So now I'm looking to do a swap 3.5 hybrid. I'm looking for details on how to go about it. If there's anyone in nyc or close by who has completed the swap is really appreciate everyone's help
