I ordered an LSXRT intake from Thunder Racing a few weeks back. I cannot get a response from FAST or them on fuel rails to fit my 2003 H2. Does anyone have any new info on it?

Are you doing the L92 heads too? I think you can use your factory fuel rail with the fast intake.

I have been pondering doing this as well.

I was thinking of doing the FAST intake with L92 heads and 42lb marine injectors and a cam. Supposedly this setup puts out just over 500Hp.

My FAST LSXRT fuel rails shipped from FAST/CompCams 10 December. From what they tell me, other ones will not work. I will have it on my truck in a few days and then first start up on the new engine. I am using the 317 heads and FAST injectors.

The LSXRT will not work with L92 heads, the intake ports are totally different. Will only work with cathedral intake ports.
