Ride: 5.0 AU's and 5.0 Maverick

Power: 139 rwkw

Location: Sydney West
NSW, Australia

Hi all
Well while Im doing the Mav rebuild it has been decided more power is in order.
This will be happening in the next few months , hopefully before the a*** totally falls out of the dollar.
At the moment due to budget it will be staying a 5.0 , but in its future a 347 bottom end from Ford Strokers will be happening.

Im after low and mid range power as it has a fat a*** to move around. I would still like to be able to spin it to 6000 but when playing.

The top end Im thinking of is:
Trickflow 170 Twisted Wedge Heads
Comp Cams XE270HR-12
Comp Cams 1.6 Roller Rockers

Now the question. Which manifold?
I currently have a new style Performer RPM II on the truck now. I also have an explorer manifold sitting in the shed that I can port out the same as the T Moss guide.

For what I am after which manifold would you recommend?

Based on that fact my Mum is the best around!

I think the Explorer would be better for torque than the RPM2

Definately the Explorer, best manifold for sub 5000 rpm.

With the rest of that combo and a stroker in it's future; RPM2. Before the stroker; Explorer.

Exactly my thoughts as well. Even on a pretty reasonable 347 up to 4000-4500 a ported Explorer intake will be in front. If most (90+%) of your driving will be between idle & 4000 then stay with the Explorer. The XE270HR-12 I would suggest running with 1.7 rockers, even if you go the 270HR-14 I would still use the 1.7s
