I do have MSD electronic ignition, I installed...I think to keep things somewhat simple for me, I'm going to request the  9.5:1 comp if I choose cast heads, and 10.5:1 if I go w/ alluminum, as suggested in the posts.  I'll advise the builder that this is want I want. 

I'm still not sure if I should use Stage V, stage VI, edlebrock or Indy. 
I think that due to being somewhat novice and being my first build, I should start w/ the mopar, and move up if I feel necessary.  I can do head changes myself, if necessary.

If I go w/ either one of these combo's, w/ the 6pac, what cam would be best.( specifically)  I think all the tech stuff is a bit over my head,and would really do best w/ an exact part.

I think I'm going to pass on the strocker kit at this time.  I'm getting too many offsetting opinions.

I don't think it's going to be too hard to improve on what I currently have.

my choice would be to use the Indy EZ as the first choice , the Stage 5 are good but still have the open chamber which is a draw back trying to create quench , stage ^ are the most expensive choice & I don`t like the eddy head + the EZ will give more potential for further development without buying yet another set of heads
I will have to reveiw the whole thread to see what cam would be a fit
 the 10.5 compression should be bang on & I would use the speed pro flat top L2355F piston, this will give you the comporession you need + the advantage of a flat top piston
Use Cometic head gaskets to prevent gasket failure using Alum heads & iron block
 are you looking ofr a Solid or Hyd cam ? , I definatly prefer the solid cams

Well, as mentioned I did already buy a mopar purple cam 292 duration hydrolic...Sounds like that's not the best choice. I will exchange if necessary

I don't think I understand what the differences would be between hydrolic vs solid lifters are.

With that piston you mentioned, would that have the relief for the valves?

Also with the indy heads, is there a cc that you'd recommend or are they all the same?

the pistons have the valve reliefs & give you 9.4 :1 compression with 906 heads / Open Chamber  , the EZ heads have a smaller 76 CC chamber which will raise the compression by approx 1 point from 906 iron heads ,  giving you 10.5:1 approx
 
 Personally I prefer solid cams but they require adjustable rockers & new pushrods

 :iagree: Probably the easiest way to go at this point is just a basic rebuild with the 6-pack pistons and have it balanced. This will give you around mid 9's compression which is fine for pump gas. If you need more later upgrade to the aluminum heads. The basic indy ez's will bolt right on and the resulting compression will still be pump gas friendly. These heads won't need any surfacing because the chambers are allready the right size.

The eddy's have a larger chamber and would need to be trimmed down to decrease chamber volume to 75-77cc to achieve the same compression ratio. The other option with the eddies is to zero deck the block with the six pack pistons.

I can see that you're overwhelmed with all this information. Engine building requires careful planning and execution when trying to science out the best combination. Different parts have difference specs and this needs to be considered when speccing out the combo. The different head chamber volumes ultimately impact on the shortblock build, specificly where the piston to deck measurement needs to be.

To keep it simple, have the engine rebuilt to stock specs with the 6-pack pistons. This will work fine with the factory open chamber head and in the future with a 75cc Indy EZ head...should you choose to go that route. I'm in agreement with Chryco on the solid cam...they work better. The MP 528 solid would be an excellent match for the iron head build you're contemplating now and would still work in the future with an aluminum head upgrade.

I think you'd be very happy with the 6pack and MP528 cam.  :2cents:

I use the MP 528 with 1.6 rockers all the time , it makes great power

  Get the 528 solid it's a great cam, every time I've seen a mopar at the track with one, it ran hard and Idled well.
 Remember your starting with a 440-6pac at around 390 HP! so it's already a very powerful motor. Add some TTi headers, good flowing mufflers like Dynomax, a X pipe, a clutch fan if you don't have one, K&N air filter, and maybe clean up the ports on the heads and match them to the intake get a good valve job and call it a day. With all the money you'll save not going with a stroker and aluminum heads, get yourself some good gears for the rearend if you don't already have them. You don't have to break the bank to make a mopar run hard.
 Good Luck.

I'll look into the 6pac pistons, as well as I'm leaning towards indy ez heads.   I'll also check out the 528 cam.

Thanks for all the input.  Again I'll keep you all posted on my final choices.  You've been a great help.

By the way, I thought, I's share my new license plate...I want to be able to sport it w/ my head high.

PS.

I figured out how to reduce the file size so I can post, how do you change the actual size???
