Friend of mine is looking for one that will hold up to 800hp at the wheel that won't split apart. He's thinking the 2003's and up are the better ones to get a hold of. Does anyone know where he can find a core? Vann recommended www.car-part.com, just wondering if anyone has any other ideas?

He's got someone that can built the tranny if he can find a core to start on. Thanks!

 

If someone has the resources to build an 800hp 4L80E they should be able to find a core.

 

Clint/Stacey dont know which one of you posted. I found a place for chris that will build one to hold 1000+ im going to be giving him a call on it soon. problem of course is going to be price.

 

here is one for sale
