If FAST is going to make a TRUCK intake that suppose to be for PERFORMANCE then why the hell not make it for the L92... There are 4 billion types of intakes for the 317s and little for the L92, which it the REAL performer out of the 2 TRUCK heads... ehhh... some companies

This won't do me ANY good on my 450 stroker... damn I'm pissed

On the flipside, the better the heads, the larger the restriction a stock intake represents, the larger the gains swapping to a really good ported manifold.

This is a 2006 cam only truck guys.....stock 6.0 shortblock and a pretty healthy cam (high 230's @ .050). Obviously an auto trans and this truck has a two piece driveshaft as well.

The gains from the intake swap blew my away (this is literally the ported intake I posted pictures of in my earlier posts a couple of weeks ago). Customer has given me the greenlight on a "Mamofied" set of AFR 230 heads and we will be going back to the dyno with the head swap in about 4-6 weeks or so if I had to guess. That should be cool also in and of itself to see what just the head swap can do for us.

In the meantime, check out the fat gains we made with the stock 317 heads!




BTW....at 6500....a very usable RPM for this combination, we are up close to 60 HP!!
