Ok,

I have a 4.8 with like 1000 original miles gen4 super clean like dripping in gold flakes and mustang crushing dreams,

I also have a set of old prc 2.5 243 heads

along with a tsp blower b cam
lift intake .640, exhaust .647 duration intake .227 exhaust .235 with 114 lsa

looking at a ls6 intake, figured 1 7/8th headers flow in and out best I can

the cam is designed for a ls3 which in a couple years id move to. Figure d1sc would be plenty for the 4.8 but with the goals a ls3 after a deployment or two,

an f1x would be better for that but maybe too much for the 4.8

end goal is like 650 or more rwhp

open to suggestions and what not. Want to get the car up and running again as I sold my lsa ls2 w/ ls3 top end and need that blower whine.

All of that sounds wonderful. Put it together and let us know how it goes.

Well Im really looking for suggestions on blowers suppose I should have made that more clear. I have found like 3 people running an f1x on 5.3 with good results but its on a stand dyno not driving.

The D1SC seems like it would be a better match for the 4.8L but if you plan on upgrading to an F1x then you might want to start with that.

I don't believe I've seen any F series blowers on any 4.8/5.3 combos but I was around 650whp with my sbe 5.3, 317's, 223/235 116, 8.5cr, D1sc. LS3's with the d1sc can make over 750whp with your cam

I would prob watch the valve to piston clearance with the cam, the 4.8 prob has flat top pistons-I would imagine you would have to spin A D1SC up pretty good to get good power, so you would have to watch blower speed
I hear ya on the blower whine, I miss it, although I can hear my turbo winding up inside

F1x is a 1500 HP blower. Seems to be a little overkill for a 650whp 4.8.

That should work. The cam might be a bit too large for the 4.8L though; but, the D1SC is right blower.

I know when my LS2 craps out, I am jamming my D1SC on a 4.8/5.3L and cranking up the boost.

A D-1SC can make 750 to 800 rwhp and is good for low 9 second in the 1/4, it sounds ideal for your plans. Bob

There have been some 5.3 with an f1x putting out very good numbers.

I recall one that was a stock bottom end with an f1x that pushed out over 1200 hp on an engine dyno. Believe it was on methanol, and it had a crazy cam profile to move the power very high in the rpm range to help keep the heads down.

Andy Fangman I believe.
There is a video on youtube somewhere on the engine dyno.
