Please share some internal pictures of your ported Indy intake manifolds. Will be using the single 4500 for 440-1 245CNC heads. Anything to do differently if running Alky?

ill try to find an old pic of one I did that worked well correcting distribution without removing length from the runner dividers. if you look straight down the throttle barrels trajectory, you'll see why they bias fuel towards the outer runners...So, I undercut the divider bottoms with about a 3/4" radius then radiused the inner walls to a near point on the outer runner edges...especially on top...never knife edge the leading edges. If no one posts one done 'correctly' here look at the general practices that you will find posted on YBullet in the engine section. Another thing that can be done is give it more plenum via spacer...that will help distribution as well....other than this it is a good manifold.

Yes, I would love to see some pictures of one done right. The port dividers were my biggest question. They are not right the way they are now....that's for sure.

I don't know why Indy did this with the runners but I am interested to see also as I'm about to do the same. popcorn

I would also like to see how guys have opened up the transition to the runners. Mine looked like it needed a bunch of opening up especially for 2 1/8 blades, which I did.

I started doing mine but my poor old air compressor died... should I be taking more out from the bottom of the runner?

I think the Super Victor is a better intake to start with.

maybe so Andy but many of us don't have the budget to endlessly buy intakes plus being downunder makes for double the cost, we gotta run what we brung or what we can get our hands on at least.

That looks 1000% better than what I currently have. I guess I will take some before and after pics of mine. Time to make a pile of chips.

It looks that good b/c Wilson has already ported that one.

I thought the Victor bottom end didn't compare to the Indy


71 demon stock stroke 440/indy ez-1 running 10.10 @ 132.14 mph in the 1/4 and 6.36 @ 107.46 mph in the 1/8 not in the same weekend but It did it then I sold it.

On my 440-1 CNC 345 4500 intake that i ported out it ended up kinda looking like the intake Andy posted as all squared up in there in the plenum and not like the stock Indy with that extra aluminum cloverleaf look. I also took a little more off in the outer 4 runners in the plenum are to help make the plugs look better and more equal, still wanna take a little more off there yet. I only have a couple basic pics but can try in get more stuff is at my garage. I did bring the dividers back some also.
