Can some one tell me what AN size are the fuel rails..if they are 6AN what thread is on the rails themselves?? 3/8 npt or an AN thread??on my truck with return style fuel injection i have all 8AN fittings and steel braided lines from my FP Regulator..just hoping they arent 6AN,

Also i have a lq4 6.0 with ported 241 heads, 230/226 /597/.565 cam 150 shot of nitrous on my truck should i got with the 85mm intake and throttle body or should i go with the 96mm intake and find a 90 mm throttle body??
all i may ever change on it in the future is forged flat top pistons and ls6 heads

Im in the process of putting that manifold on my car but Im not positive what threads they are but I think they are 3/8 npt.Once agian Im not possitive. I have a cam only car and I went with the 85mm and I plan on doing heads this summer, but the 85mm throttle body is about 3 or 4 weeks out.

so they dont even have the throttle bodies out yet?? they have them in our dealer catalogs at work but theres been a lot of professional products that when we go to order we have to wait two weeks and then find out their not even into production yet
