The next step in the process will be the installation of a FAST 102 manifold and TB. Shawn is convinced there's power to be made with the addition of these. At this point "In for a penny, in for a pound"

Ford Green Tops = 42lbs at Ford fuel pressure. At our pressure they are more like 46-47lb. Plus, I run a return style fuel system which will support a few more HP than non-return style.

That Richard!

Thanks Shawn. We'll all have to wait a little longer but I'm sure it will be worth it.

And they say the FAST isn't worth anything

The amazing thing Tom is that this cam proportionately is MUCH smaller than the cam you're running in the 346.

Scaled for a 346 the intake on this cam would be in the teens.

i only run a 224/224 581/581 112+4 in my LS6

But I know what you mean. matching all the components to get the desired out come is more important then CAM Q Intake B, and so forth


I actually like small cams

I LOVE small cams. Properly done you get great average power. I remember your cam from when we spoke and how you use your car. Big cams are nice if you drive your car on the dyno or only 1320 ft at a time.

I wonder if you'll be able to resist the call to go 1320ft in the "cruiser".
