indy 440-1 heads

[mally69]

these heads use an external oil line  ok,  but i dont understand what all is need and involved   with using and external line   help fill me in with info

[firefighter3931]

The -1 is a race head with big ports....not what you want for a street car. These heads will make your car very sluggish at low engine speeds and produce a narrow powerband that you won't much like unless you drive at 4000-8000 rpm. 

The external oil lines are to provide rocker arm lubrication. Basicly, the lines tap in at the back of the block where the oil pressure switch port is located and feeds the rocker arms through those lines. This is different from the stock method where oil is transferred internally to the rocker shafts through the heads.

The external method increases the volume of oil to help lubricate and cool the valvetrain which is helpful when high lift roller cams, roller rocker arms, big spring pressures and high rpm operation are being used.

what heads do you recomend???

would the 440-SR be a better choice?

you may want to look into the EZ heads which are internally oiled and use the stock exhaust ports. they are also available cnc ported. They offer the 295 cc and the 325 cc head. The 325 cc head needs offset rocker arms and is designed for larger cubic inch engines

It really depends on how much you want to spend and how much power you want to make. The Indy heads cost more than an Edelbrock but have more upward potential. The SR's have a raised exhaust port which requires a set of $850 TTI headers. The EZ heads have a stock exhaust port location which can be made to work with more economical headers. To get the big flow numbers out of either, they have to be max wedge sized on the intake ports. This means that you're into an Indy single plane manifold and if you want to run this in a Charger, it won't clear the stock hood. It will be hood scoop time. The indy heads also require the use of a specific valley pan...the stock intake gasket setup won't work. There are lots of little fiment issues that can creep up on you during the assembly process. The Indy's will also need some machine ork as well....specifically the valvejob and guides, so plan on that additional expense.

The Edelbrock RPM's are a lot more user friendly. Basicly, everything that is stock will bolt up. Header fitment can be an issue but there are a few budget header options that will work fine for that power level. Factory rocker arms, intake gaskets, manifolds and valvecovers all bolt up. In terms of power the E-heads are a good choice for a 500-550hp 440 and will make 600hp easy with a 500ci stroker build....on pump gas.

It really boils down to budget and power expectations. For a streeet/strip car my preference is towards a small/high velocity intake port. The throttle response will be much stronger and the car will be more enjoyable to drive.

what its comes to is a daily driver with 600 600+ hp is what im looking for   plus the easiest way to get that 600 hp is what im also looking for

[mally69]

  what  size header would you recomend for 500 cu in   running 440-SR heads with max wedge ports ??  OR
vs. what header size with ported eddy's

i thought you could buy the indy EZ and SR completely assembled   minus the rocker shaft and rockers

[Chryco Psycho]

I would use a 2" primary tube header for a 500" EZ head big block

The SR's have a raised port. TTI makes a step header specificly for this application. You need that header with SR heads and a 440 block...nothing else fits.

Both the EZ's and SR's are available fully assembled but that doesn't mean that they're ready to run right out of the box. The valvejob is often poor to average and the guides might need some attention. The same applies to the edelbrock heads, but the valvejob is better on those than the Indy's.

With a 500ci build looking for 600hp....a 2in header is what you need. TTI has a standard ex port header that will work with the E-heads or EZ's. I have a set for mine and they are well worth it....especially with an angled plug head. More clearance for plug wires and easier plug removal and no clearancing required.

Mally69,  I would suggest you contact Scott at Straightline Performance ... link > http://www.straightline-perf.com/  I can't recommend him enough.

I've been beating on these cars since they were new, with decent success, but I have to say that his parts recommendations, particularly cams, are better than what I come up with. His custom grinds are specific for your application, and are about the same price as a shelf cam (sometimes cheaper).

His prices are competitive, and he may be able to supply everything you need to achieve your goals while saving you a bunch of money over your own approach.

My guess is that E-heads w/a port touch up, a Holly SD, and the right cam for your car weight, trans, use plans, etc., will get you what you want at a couple thousand dollar savings over a more exotic approach that will produce the same results.

Give him a call and see what you think.

hey guys you've all been very helpfull Thanks,    it seems as if the eddy or EZ heads would best fit what im trying to do  i apretiate all the info  Thanks.

Mally, here is something that may interest you. The previous poster mentioned straitline peformance. On his site is a 493 he built with E-heads that runs on pump gas. It made some good numbers on the dyno : 654hp/653tq

    Now that could be LOTTTTTTTTSSSSSSSS  O'FUN...........     

[mally69]

wow yea those are the numbers i  like to see    its putting out the power and doesnt seem to be revvin the heck out of it,  im DEFINETLY going to conact them about that build.  thanks for that link firefighter i missed that when i looked at that site earlier today.

[firefighter3931]

Exactly ! This is the point i'm trying to make about a high velocity/small port stroker build.  The power comes in where it's actually usable for a street driven bruiser.

SP's 496 looks to be a really nice engine !

Curiously, they seem to be using an INDY Single plane 440-2 Intake manifold, on the 496 picture with the Eddy heads ?

I'm wondering if the eddys are ported to max wedge size ? 

I may be wrong, but I don't think INDY makes a "single plane", "906" stock type port window manifold, do they ?

[mally69]

scott said that it was an  edelbrock victor manifold

[Challenger340]

OK, me bad, sorry, that makes much more sense !

[Blakcharger440]

Will the factory stock 440 block handle that much torque and HP for long?
I have heard they are good up to about 600HP but too much over and you are pushing it.
