Eagle 383 rotating assembly question????
"Eagle" 383 Rotating Assembly question.
This post a few weeks back will mention what my intentions are:http://forums.corvetteforum.com/show....php?t=1595844.
Since that post I have purchased the TPIS Miniram with fuel rails, and a set of AFR 195cc Eliminators. The next thing is to pick out a 1 piece real main seal rotating assembly.
http://www.cnc-motorsports.com/produ...092&CtgID=9038 This is the assembly I have narrowed it down to. I was curious if there are any members that are currently running this assembly. It is my understanding that it needs to be internally balanced, and for the cost of around $100 you might as well let the place your buying it from balance the crank/rods/pistons.
You can press on the link above if you wish for all the information and price. Below is what I copyed and pasted.
"ESP" Full competition rotating assemblies are the perfect choice for racers desiring a bullet proof bottom end peformance engine.
New Eagle 4340 forged steel crankshaft ( late Style 1 piece rear main seal 87-99 blocks).
New Eagle "ESP" 3-D H-Beam connecting rods ( Bushed Fit Pins ).
New SRP forged high performance aluminum pistons, with pins and locks .
Premium Plasma moly performance piston ring set.
Clevite 77 high performance H series performance rod and main bearing set.
Kit must be balanced if not done by CNC-Motorsports.
The heads I have chosen from AFR are 65cc combustion chamber. I am thinking of dropping the piston in the hole approx. 0.010 and with a head gasket of .039 would give me a CR of around 10.7, and a squish of .049.
Just curious as to what you guys think. I am able to get this assembly for $1353. And the store mentioned to me that a standard crank balance, like what CNC and Eagle do are $100. If I want a race balance with rods and pistons matched as well it's $150.
Anyone running that assembly? What do you guys think I know Eagle is not the "best", but my budget does not allow a $2500 rotating assembly.

That is what I am running now. I can't remember the exact price I paid for balancing, it was around $250 for mine. My kit price was about $300 higher that that one, but this was in 2004 that I got mine. Runs good. I wished I had gone with more compression though, I picked the -16cc pistons instead of the -5cc srp's. If you are running n/a, then go with the -5cc's for more compression.

That sounds like a fine, fine package idea. I have that one, or it's equivilant anyway. I bought my parts in 2000 and it was like, $1700. So prices have dropped since then. They didnt make a kit back then so I ended up buying Lunati forged pistons. My compressiion ratio is 10.6:1, and it is just great for 92 octane gas.

You'll be fine with the Eagle stuff, definately have it balanced as precisely as possible. It's wierd that they have a half assed balancing program at a reduced cost. If you're not doing a power adder, I think you could do a Scat bottom end for much less. Scatt 9000 crank, Scat 7/16" rod bolt I beam rods, piston of your choise, etc. Flatlanderracing.com is what I normally check for pricing on stuff like this. It could actually come in 50% cheaper than an overkill eagle 4340 assembly.
I did the Eagle 4340 stuff and a Diamond piston but it's for a mild nitrous setup and should be reliable well past 700-800hp. If you can save on the bottom end, you casn always put the rest towards a better header/exhaust and intake mods that you may need. Goodluck!
