Hey everyone,
I've got a 99' f150 4x4 extenda cab 5.4l 3.73
I had the spark plug blow out the head, now that i got it all open I'm looking for a beefier bottom end.
I see that ModMax has a stoker kit 5.4 to 5.7/5.8 and i'm wondering if anyone has had any input on weather this is a good kit or not.
I am also looking for some performance heads:
will the fr500's fit on a 5.4 modular engine?
how different are the flow rates compared to the heads I have now(with 1 heli coil)?
what about the stock navigator heads 32v ?
I would appreaciate any comments
Thanks
SetDecGuy
does anyone know if the 2000-2003 mustang SVT cobra heads will fit on the 99 5.4l block?
Does anyone have any flow rate info on cobra r heads, navigator heads, or the SVT heads?
