440-1 indy top end install prep

Will my 470 low deck stroker is getting closer then ever to becoming a reality. My pistons will be here in about 2 weeks then i can get my rotating assembly balanced,and final bore on my block machined.
Before i have the block final machined. Im wanting to make sure all my oiling mods are done. The oil delivery setup is a single line with swing pickup and a high volume oil pump in a 7 quart pan.Ive done all the basic mods like clean up the oil orifices and drain back channels in the lifter valley. All the excessive casting was cleaned up and the block has been clearanced for a stroke assembly. The block was squared up and the pan rails were leveled up when the BCR gridle and main caps were installed.

I know the Indy 440-1 heads been on the market for close to 20 years now so I'm sure alot of members have used this same setup over the years,whats some of the pit falls and problems you guys have had to deal with when upgrading to this head package.
Heres a couple questions i have hopefully you guys can help me thru before i start the final assembly on my motor.
1.perfered oil delivery setup for harland sharp rockers
2. Soild roller lifter choice
3. Are they any oiling mods you guys have come up with that help save the rocker gear?
4. Intake plenum mods for a 440-3 intake(runners are getting gasket matched this week)
5. Perfered valve springs for a solid roller cam with 630 gross lift
The heads have only been gasket matched and the casting flash was cleaned up. When funds become available the heads are going to be ported and polished but realistically that wont happen till next year.
Any and all help is always appreciated and Thanks in advance

Indy heads oil externally.

You need to get the spring requirements from your cam grinder for that specific cam. Or have the cam card handy and call one of the big companies and have them recommend a set.

Like Trendz said, the heads have the external lines from the back of the block to the heads. You'll likely have to put restrictors in the fittings b/c w/o them, you'll lose a lot of pressure since it'll flood the heads w/ oil. Normally use .060" restrictors in the fitting on each head.

So no need to mod the #4 cam bearing,beacuse the heads block off that oil circuit, correct?

Correct.

I have restrictors in my oil line fittings.

Anyone find the need to add spary bars to the valve covers without running jesel rocker arms?

Are there any tips for cleaning up the plenum on a indy intake,pics would be awesome

Ive been buying parts for the last 2 years for this build and its finally coming together

Thanks for the reply guys

Give me(Bob) or AJ a call or pm at BGR with any questions or concerns.We have been building race and street engines with Indy componants since 1999

I have Indy SRs w/ Harland Sharp rockers. No need for a spray bars.

There are/were 2 versions of the 440-3 made. One was a little rougher than the other...it was just a plunge cut 4150 flange manifold and had big flat steps at the top of the runner divider. If yours is like this, you need to blend them in.

Here's what the "better" one looks like. Dividers are cast and not cut. Nothing wrong w/ the latter, just needs a little blending to smooth everything out.

Heres what i got i believe it looks like the second one you posted.
I was planning to knife edge the dividers and blend everything in. Was the plunge cuts for running a dominator style carb? I thought i read somewhere it was better to run the 4150 baseplate manifold and do some mods to accept a dominator baseplate?

You have the 440-2 manifold which is 4150 flange. The 440-3 is 4500 flange.
Yes, many say the 440-2 manifold w/ the tall 4500 adapter makes more power than the 440-3 manifold.

[censored] K sorry im a tard I work way to mine hours and dont sleep enuff.

Guys sorry any good mods that are needed for the 440-2?





Thanks Bob ill definitely use your number thank you

DO NOT knife edge the dividers. Just tootsie-roll the leading edges, you can also 'work' a non-biasing radius at the floor of each too. You'd really do well to have a professional shop measure-up and assemble those heads...plenty in the area. My 2 cents.

With your new Indy heads as said they external feed oil, instead of looking for ways to get more oil to the top you may be looking at having less. 2 things: Rocker cover vents should be at the front and there are restrictors availiable to reduce the amount of oil to the top.

Thank you thats sound advice

Ill keep that in mind

Ask around about your choice of oil pan. I don't think seven quarts of oil will keep it happy, especially on decal after the run. I had trouble with 6800 rpm and 9.5 quarts, uncovering the oil pickup and seeing very low or zero pressure for an instant on the brakes.

The Indy manifold,especially the 4500 manifold should have the dividers removed from the area below the carb or at best tapered from the top to the floor.This will allow for a better plenum box for fuel and air to blend and give a more balanced blending and evenly distributiation to all cylinders.If you run it as is the four corner cylinders(1,2,7,8) will always be richer.

Ill look into finding a different pan thanks for the warning, i really wasnt sure what would fit in my little valiant theres not alot of documentation out there on the web about putting a big block in a 62 valiant.



Bob i can see what your saying about the dividers need some work,you wouldnt happen to have a pic of the work your talking about? Im curious to see just how much material to remove, i had planned on bring the dividers to a nice sharp edge(knife edge) but apparently thats not what i need.
I was able to put 2 hours into gasket matching my intake this morning and was able to get three ports on the runner side cleaned up, i figure ill have atleast 6 hours of cleanup when its all said and done.
Thanks all for the help

Just cut the deviders back and give a nice rolled end as mentioned.With the dividers In place as cast will cause the wet fuel from the carb to be directed to the four corner cylinders.Let the fuel drop and and the air entrain with the fuel filling the plemum with atomized mixture.Leave ruff sanded surfaces at the runners and floor to help this occurr.
There are a few customers that have our modified manifolds,maybe one will post a picture.

Are you running EFI?

FastmOp not at this time i was planning to use a megasquirt 2 i built a couple years ago thats setting on self but realized it wouldn't work for my needs, also i have everything for a high hp e85 blow thru carb minus a main body so thats the direction im taking this year. Plans in the near future are to atleast back halve the car but id like to full tube chassis the car,and switch to efi then. Im probably going to set the motor up with provisions to add efi in the future by adding,maf,gm style sensors for temp,oil pressure,air inlet temp,crank tigger.
I know blow thru is a pita but honestly there not that hard to tune if you stay under 15 pounds of boost. Over 15 your going to need a "crutch setup" which ive dealt with, and still have the provisions hooked up in the car from when i had the slant installed in the valiant and i was running 20 pounds of boost.
Aaron

Greg are you running a stock K frame? If so which pan are you running? Not a whole lot of room in there.
Would something like a oil accumulator (sorry not sure if thats spelled correctly) added in the system help? I was think of something in series with the oil pickup line or will that cause pressure drop or inconsistents in flow and pressure.
Thanks all for the help

This is what the plenum of my 4500 Indy intake looks like.

Another

I use a .039 oil restrictor on both my Indy SR and 440-1 with the older full roller needle bearing Harland Sharp roller rocker arms with a solid roller cam I used the same size restrictors on my newest motor with the Eddy M.W. Victor heads with the Harland Sharps on it also

I have a tube chassis, so can't offer help on what will fit your car. A lot is going to depend on how much rpm you are going to turn, weight of the oil, and G forces. Maybe starting another thread on oil pans for your project is the way to go.

I have a nice E85 4500 custom carb set up for blowthrough that I won't be using. Shoot me a PM for details if you are interested.

With a good pan I've run as low a 6 qt's with no problem on accel. Hard finish line braking requires at least 7 qts .

Well ive put in about 3 more hours gasket matching the intake runners im going to need a handful of new sanding cartridges of 80 grit before i can continue plus im off of work the next couple days so i wont get back to it till thrusday or friday. Yah im doing it on the clock......

Cab thanks for the advice im going to check the size of the restricts that are installed in the head and make sure there atleast .039 and not just a normal AN fitting.

Greg thanks i thought your car was tube chassis but figured it wouldnt hurt to ask. There another thread started about big block A Body pans thats been helpful in helping me locate a affordable 8qt pan that should drop right in, or i could extend my 7qt another inch to get atleast 8qt.
You mentioned rpm plans are to short shift this thing at about 6500rpm but ill have to see what the combo likes. I have no plans to stress the block from over reving it as there should be more then enuff power and torque to achieve my goals. If not ill turn the BOOST UP

Thanks for the pics that helps me out considerably i havent touched the plenum aera yet im still trying to figure out how to cut the dividers down but will give it more thought in the next couple days.

Airwoofer ill pm you later today about that carb as stated in a pervious post i have some new parts to build a nice 4150 carb.

Dvw thanks Doug for the advice and looking forward to meeting you in person

Well im off work tuesday and wensday and plan on working on my junk the next two days probably going to try and finish the mini tub,and I may install a couple more bars to my cage ill need to finish it up before the car is ready. Also i need to start test fitting the powerglide. Ill keep you guys and gals posted,and im sure ill have some more questions
Thanks again all
Aaron

If you choose to try the seven quart pan,(or any system for that matter) a 30 psi or higher pressure switch to the oil system and a light you can't ignore might be worth the trouble. During a run it is not easy to see everything, and a 30 psi or higher switch will let you know if there are issues with your setup. Put it next to the oil pressure gauge.

Thanks greg thats sound advice i just ordered one off ebay
Check out this item I found on eBay: http://pages.ebay.com/motors/link/?nav=item.view&id=311567553384&alt=web

Check the pushrod to block clearance on a low deck with 440-1 rocker offset. I forget if this is mostly a problem with offset lifters or if it is close with regular lifters too.

I will see if I can find an old post with pics.

Thanks for the heads up 440Jim im going to grind mine down before final machine work is done.

What you guys running for solid roller cam bearings i hear alot of guy running king brand but i have no exp with them? Any and all help is always appreciated
Aaron

I also have a 470 but i'm thinking of swapping my -1 heads for BS heads, would i just blank the oil feeds off and go back to conventional oiling ?
Sorry to hijack your thread.
