Tunnel Ram 6 Pack - Mechanical Linkage

[Chryco Psycho]

the ones I have seen use a common rod between the front & back carb & a slider link onto the common rod with a adjustable stop on the rod using a setscrew , the center carb /slider rods is mounted lower on the arm to allow it to move 25-30% before opening the outboard carbs but they all end up @ WOT at the same point , this should not be hard to fabricate

If you need something done or need more info you can contact me direct as this is the type of work i do    The parts needed will be an Edelbrock slider rod to join the front and cnter carbs and a custom fabricated heim jointed rod joining the front and rear carbs.

Bit late getting back to this but I've been out working at Mt Isa (abt 600miles west)for the last couple of months.
What I've made sounds pretty well much as ChrycoPsycho describes above.The local carby shop wants in on it and he's been a great help too.
Hemiken - thanks for the offer.Think it's under control now.I'm just an independant bastard
Will post up pics when I'm finished and happy with it

Sorted and runs pretty well
The cable pulls the front carb from the other side.
I've had a change of thinking and running the two outboard 350s as primary carbs and the centre 650carb as the secondary.

Made the fuel rail and secondary linkage myself.

Well...1st time out,straight off the trailer,it ran a 12.1@109 which is as quick as the best it's done so all is good

[hemiken]

  Congrats on the 12.1 off the trailer. good hard run by the sounds

[nqkjw]

Yeah the car works well for a pretty ordinary engine.
it's only got a MP 484 camshaft and a lot less compression than it should have since it burns it's share of oil
Shifting at only 5200rpm.

[hemiken]

What size stall convertor are you running ? 3000 or ?

[nqkjw]

It's a dominator built for 4500 with 650hp (future plans) but will still stall at 4000 with what I've got now.

[nqkjw]

For those interested it's now gone 12.05@110.3 with 1.68 60fts.

For those interested in the tune the jetting in the primary carbs(2x350cfm) is 69s with 35pvs.
The secondary (or thirdary? ) 650cfm carb has a 3.5mm drill bit through the jets and no pv.
Total timing is 37 degrees.

I've worked all around this tune and the rear end to try and snag that elusive 11 but just can't seem to get there with no cam or compression.
