Hey guys,

Long story short, I recently purchased a motor that is said to have a Callies stroker crankshaft, that has a stroke of 3.825". Doing some research, I haven't found much about it. Google brings up older ad's/pages that list this crank for sale, but everything is old/deleted or unavailable.

My question to ya'll, is did Callies ever make a 3.825" stroker crank? Like my engine builder said, it's not much of a power gain over the stock crank. Most guys put a 4" stroke in their builds.
Is there any gain of using this crank?
If Callies did make this crank, why don't they make them anymore?
Are they known to fail?
Did they just not sell well/weren't very popular, etc?

When googled, I come up with Callies Dragonslayer crank. I was under the assumption that Dragonslayer is a totally different brand?

Help me out ya'll, thanks!

The dragonslayer crank in the old small block chevy engines is their
high end crank.. Very $$$. To rich for my blood..
As to the applications to LS, I have no idea

I would call Callies if you want to identify which model the crank is. I have not heard of any failures. If the crank was dropped it was likely due to low volume as most would just go 4".
