Install Pictures of Aussie4v Holley 600 CFM- Aussie 2v to 4v

[Mustangaroo]

Well boys Little Roo did most of the install last night, here are some of the pictures that were taken, I'll shoot some more when I have a new air cleaner and filter and the engine bay cleaned. We only drove around the block once last night as it was getting late and my six is a little loud We did a little tuning but more still needed, she does run and you can feel the power of the 4v when she opens up! This is a old 2v intake I hacked into a 4v and had coated and polished! 8)

At a minimum you have raised the level of cool factor for your engine. I am however very interested to see the performance improvement if any. What you really need to do now is pop off the head put the biggest valves in that it will take, 3 angle cut, and a nice hot cam to take advantage of that 4v.

I had hoped to have my install done by now but I have two herniated disks that have stopped me in my tracks. Engine is in the car but without a header, intake, etc...

I have had four angle valve work done, but stock valves and stock cam. I do have 1.6 rockers and 10:5.1 C/R. Plan on keeping the stock cam untill the engine needs a rebuild, only problem is I only have 10,000 on this engine.

Definitely a cool addition. I wonder how your gas mileage is gonna start to look

Ben,

Are you using 91 octane w/additive? I know you got skills so give us the 411 on your secrets.

Dennis,
Nope! No additives, Using old steel gasket about .018 and head cc'd at 47cc (milled lots) my son's is 58cc on the Aussie head, I must have found the sweet spot as during winter I run 89 Octane and summer 91 Octane but no additives, and no pinging...and yes running about 12* BTDC

One question, is that PCV hose hooked up to the #5-6 intake runner? I may be finicky, but I would want that hose closer to the plenum or carb base, where it might have a lesser impact on mixture/vacuum for the end cylinders.

 

[Mustangaroo]

Bigred,
It was just connected this way for a quick test run as the hose was too short to reach the carb base.

I can't wait to get my intake back from Der Heckmeister. He's working on it to make it a 4V carb as well.

Just out of curiosity, when you ground the base down, did you angle the front of the mount up? Al found that on the original 2V intake, the mount has about a 4* rake. Our guess was to keep the carb level since the engine is angled down. He's working on maintaining that 4* rake with the 4V base too. Not sure if it'll make a difference, but just wondering.

The angle on the pad was so the aircleaner cleared the underside of the sheetmetal. Being to the right and higher than an eight, clearance was restricted. Al might consider tapping and drilling the two raised bosses above runners 5&6 (usually undrilled new). You never know what might conveniently bolt up there.

CobraSix, Addo,
Yes, I keep the angle by rasing and building up one end when welding, before you cut the intake or weld it make sure you have enough room for your 4v carb to clear the shock tower I had my mounting base welded up 1" 5/8" from the edge next to the head and meassured to the center of the carb bolt hole. My carb just (modded with hammer) barely fit!
Addo, I dirlled the two raised bosses above runners 5&6 and put in heli coils, thinking of mounting my Carb linkage in the near future.
