i need to know where and what kind of restrictor you guys are using in the Indy 440-1 heads to slow down all the oiling to the heads??? thanks

i just tapped mine and use holley jets,i think ive got 65,s on my Indy 325-EZ,s

.050-.075

What does this do.. Does it help with performance. Or is it just to keep the oil in the block..

it keeps the oil out of the head,before i restricted mine the oil would fill up the head and blow out the breathers,it also helped my oil press.

Bonefish, You tapped the end of the fitting that screws into the back of the block and then screwed in a carb jet into it then screwed back into the block ?? is that what you are talking about??

i tapped the end of the hose where the brass is.i could not find the exact tap for the holley threads so iused a 1/4-24 and red loctite ,its not the rite thread but its close enough that it will stay. you just have to snug it in tight.i know it sounds like a cheesy thing to do but the threads areso close it actually isnt that bad.or you might be able to find the right tap.its not a comon size.but anyway you tap the end of the hose where it goes into each head, not the head. whats that goin in?

It's not cheesy,it works fine and the threads are tight,it's tough finding the 1/4X32 tap.Keeping the oil at the bearings and in the sump is better than filling the top end with unneeded oil and flooding the rotating assemby on the drain back.

Hello Billy
I drilled and taped the Y block going into the block, for the holley jet as described above. This saved me from needing to do both fittings in both heads.
I ran a .075 holley jet, which then split off to each side feeding the rocker arms. This setup worked perfect.
I ran the Jesel system, and made my own spray bar oiling lines from 3/16 brake line. This setup seen season after season of runs, and abuse, whats nice about the Jesel system, is even running spring loads approaching 800LBS open. They never moved. I checked lash about three times a season. And it never needed corrected or adjusted. IMO if the move, something isnt right or wearing.

I cant recall what size the fitting was in the Indy Maxx block though.
I know the factory blocks have two, one 1/4 and the other 3/8 NPT...

Looks to be ONE 3/8 NPT oil galley port, can you confirm?

one of my friends told me that they are using a .065 hole in the restrictor and said they are still getting too much oil.. what sizes are you guys using ?? ..Thanks guys for the great info and pics.. i will take care of that so as my car comes back from chassis shop.. Headers are being built.. *************** BONEFISH to answer your question here is what the 572ci Indy is going in..63 Dart that i have been building for the past 1 1/2 years..

another view

DusterJohn..yes that is the fitting that screws into the back of the head and then the hose attaches to it.. as was stated above you can do either the one T-block or the 2 fittings that are in the back of the heads.. i am going to do the 2..one for each head...

Kool thanks.. Thats what I'll end up doing also..
