crank size?
I really don't care that much, it your car and project, but it sounds like a lot of feather ruffling over the truth.

I am just curious why what they said was so bad. Did they flat out refuse to help, or just question it a little? They gave you honest advice. What you are wanting to do will cost more and take longer, when the same result, short of a specific displacement, could be met with shelf parts.

I worked in retail long enough to know when someone asks you for a specific item you don't ask why not this one because in most cases they've done their research on that item and have a reason they chose it. now if they ask in a general sense then yes it is ok to ask why not this one and I was asked why not this one and a custom one will cost more, wrong thing to say to a consumer if you want to make money. just because they distribute parts doesn't make their sales people genius engine builders
Like I said, I have no knowledge of how the conversation went down. however, from they way the posts read, it seems like things got down the wrong road aweful quickly.

I own an injection molding company. Almost everyday someone comes in with a new part. First thing I try to do is figure how to make the mold easy to build and less costly. Usually the customer is very happy to change some slight detail to save big bucks. If I didn't ask and just did it the costly way and the customer found out by changing a small detail they could have saved a lot of money, I would have a very unhappy customer. And sometimes that detail is a critical one so we do it the expensive way. I just figure it is my duty as a supplier to give my customer all the options and the ability to decide. This is probably exactly what happened here.

But you can't assume every customer who walks in the door or calls knows less than you because of where you work or what you do correct? All I'm talking about is running a 3.937 in an engine that has a stock crank of 3.622, it's not rocket science of how to make it work and building an engine doesn't take a genius, just someone who is good with math and building things. It doesn't hurt when you have resources experienced in the field at your disposal

Btw I forgot to mention this is going to be in a LS2, which I was recently told the safest this aluminum block should be bored to is no more than .005 over. So custom crank is in my future since I want a 396ci
You should be ok going further than that. The Ls2 has thicker sleeves than the ls1. I've personally seen them taken .030 over with no issues. However a sonic test will be the real answer.

Yep budget and this build I don't think will ever be in the same description together lol I'll take a look at Eagle and Scat and see what I come up with. I'll also call Callie's and see what they say.
I also forgot to mention this engine will be an N/A engine and will hardly ever see a drag strip. It'll be used for weekend cruising, driving in the mountains or on the coast, car cruises and maybe some autoX and/or road course.

K1 Technologies offers a 3.900" stroke LSx crankshaft. Quality wise it's probably on par with Compstar and better than Eagle or Scat. K1 is owned by the same company who owns Wiseco and JE Pistons. Something to think about.
Also, 4.020" most likely wouldn't be a problem on a street driven LS2. We're talking .010" off the cylinder walls. It's not like you're putting a blower on it.
The more I look, I don't see a shelf 3.900" stroke piston available. Those would most likely be custom.

When I was in school at UNOH, all we used in the dirt modifieds and drag cars was k1 and callies. K1 makes good stuff.
Also, most piston manufacturers will set a custom compression depth for 50 bucks over the price of 8. So custom cd pistons wouldn't be too much of a shock to your wallet. Just get 6.125 rods, and start with a piston for a 4 inch stroke and add .050 to the compression depth.
You may get lucky like I did and be able to deck your block a little and run a shelf piston. I'm running shelf pistons in my 370 for a stock stroke and 6.125 rods and I'm running a 6.100 rod. Just some time with the math can save you money.

Arun, who has run 8's in his Vette with a YSi just had Billy Briggs build a new engine with a K1 crank. Here is a link with pictures:

I also have a 403 LS2 with K1 crank & rods that I haven't run yet. It's more of a long term project at this point...lol
