Clearancing blocks, small base circle cams, clearancing cranks this has been status quoe for years in engine building. I understand ordering a package should be "bolt in" but come on having to spend MAYBE 200-300 extra to clearance the crank is STILL a lot cheaper than the other setups out there.. there are too many combinations out there to machine for every possiblity. Buy their package and all is well... using your own components and machining becomes necessary. Geez have we all forgotten what it took to get a 3.75 or 85 crank in an LT1 or stroking a small block chevy with the 400 crank while using the 5.7 rods?? small base "custom" cam, block clearancing, water jacket holes, block filler, push rod lenghts.... the LS is still the easiest motor to work on. not sayign the gripe isn't legitimate, just remember there is still technology in this stuff and high performance is high performance... now we can all start bitching about NO true bolt in adjustable valve train with NO modifications...

I'll bet the experienced engine builders and machine shops would not be surprised about this at all, but to the average newbie it sounds like a really big deal.
. When I first read this post, I realized that the answer was to just turn the crank throws off "X" amount to clear and ballance, I just thought it was shitty for the above reason. Last edited by 2001CamaroGuy; 02-22-2004 at 02:27 PM.

Ive shipped a few eagle cranks to customers that ordered them from the shop. And I have one guy that read all these posts about clearancing and says "I dont want the crank anymore, refund it because its junk". Well unless the crank is wrong or damaged etc we dont refund things without a restocking fee to cover all the credit card % charges, shipping etc. And you tell the customer even eagle might cover the extra money to clearance...but he refused to be reasonable.
How would you guys deal with this?

I would:
a) give him the option to get it fixed and therefor Eagle will pay that cost (now he does not have a "junk" crank
)or
b) if he won't do that, then take the crank back and charge Eagle for any costs.

Just ordered an Eagle 383 kit from C5 Corvette group, they insists the issue is with the Diamond pistons for the most part ( I did mention this thread! ). Someone else in this thread posted about the piston manufacturer's needing to be included in the fitment testing. This may be where the big problem came from. C5 said all the kits he has sold with JE pistons have had no issues. I am paying the extra $250 clams for internal balancing so maybe they will catch a clearance problem then.
Last, I still wonder if the wrist pin offset and/or rod length were wrong for the original kit ordered. The 6.125" rod goes with a 3.900" crank and 6.100" fits the 4.00" one. Could have been some mixup at some point? Oh well, I'll post my results when they are available.

If you look close at the pictures that were posted the counter weights were about to hit the piston pin boss area on the bottom of the piston.If he was using a6.125 rod there should have been enough clearance in that area a 6.100 rod would have been even closer also even if the pistons had the wrong compression height the clearance problem at the pin area would be the same.I don,t know if everyone is having trouble with these Eagle cranks but I personally would not want to have to machine the crankshaft C.W.s.Also the cranks should fit from the factory. If Cola and Lunati can make a crank that fits so should Eagle . :

Speaking as someone that builds a lot of engines, this is why you pay someone to do this stuff that's done it before. Often you have to clearance things yourself and rebalance stuff anyway. It is just the way it is since the crank company doesn't always know what pistons and rods you will be using. It happens WAY more than you guys would probably believe. If you buy a crank by itself you have to make it fit yourself too. If you buy a kit I think it should all fit already. I don't know if these Eagle deals are in a kit or they're just selling the crank ala cart?

Eagle should know that a standard LS! stroker build up uses a 6.125" rod. How many aftermarket piston man's are making pistons for a 6.1" rod and 4" crank? None that I know of unless they are custom order.
Besides, the Eagle rods (6.125") were ordered with the Eagle 4" crank "Helloooo McFly!"

The eagle LS1 383 CID rotating assembly comes with JE pistons that are designed to work with a 6.2 inch rod.
The pin in the pistons is .927, the reason they are using the longer rod is to help the clearance issues a little, but clearancing still has to be done on the block and crank.

Finally some resolution!
I just got off the phone with a tech guy at eagle. He said they would cover all the shipping fees for us to send the cranks back to them. (thats about $60 per crank from our side of the country) and they will replace the crank or machine it correctly etc to keep the balance good as well.
But the crappy part of this is that its going to hold up several customers motors for a few weeks.

Yep, I just got the same answer as C4Vette. Eagle is recalling all the existing cranks for re-engineering at this time. Bummer is that it will take around 30 days for turn around! I guess the motor can wait.
