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

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
