Here's the car buildup:

former LG4
355 - L69 air cleaner(k&n) - rebuilt strip q-jet - weiand action plus(egr blocked) pn 8000 - edelbrock rpm heads - comp cams 280H magnum (230 degrees @ .05 / .480" lift) - crane gold roller rocker (1:6 ratio exhaust) - holley blue electric fuel pump - stewart water pump - hedman shorties w/ custom y-pipe - 3" magnaflow cat - flowmaster american thunder 3" catback - auburn posi w/3.73s - rebuilt T-5 - clutch fan - 14 degree advance


I'm thinking that with my cam I may benefit by converting to a single plane manifold, the weiand 7525 (supports q-jets).

My current manifold is supprisingly similar in design to the weiand stealth 8016, but is a little shorter and advertised to make power to 6000, so i figure it flows enough.

Any opinions?

 

duel

 

single with a smaller carb or dual with a bigger carb!!

 

i say dual plane. is this a street car i assume? daily driver? track only?

 

Allthough you might be able to gain high end HP numbers with a single on that setup, the dual will help you out on the midrange and off idle, which you really need. I'd go with a Air Gap myself on that setup, pretty much the best of both worlds, though a dual plane intake nonetheless.

 

Stick with the current manifold. As asked above, what duties is this car having to do?

 

I don't drive the car everyday because i have a work truck, but i try to drive it as much as possible nontheless.

Right now, it drives great and idles nicely. The midrange is awesome,and the top end is pretty good too.

If you look at the pictures of the various intakes, it seems to me that the pn 8000 (mine) has more in common with the stealth intake than it does with the non-egr action plus.
Look at the runner designs and the manifold height dimensions.

What do you guys think?

 

I have the same intake, except my egr is still working. I think it flows plenty enough for anything up to a 350....an RPM air gap just may be a little better on the top end, not sure though.

IMO it's not worth changing.
