Anyone know if there is a shop in Orange County, CA performing LS / truck conversions? I have a 1985 GMC 1 ton 4x4 NP205 6-bolt with everything in very good condition except the original carbureted small block. Yeah, it actually came with a 350. For the transplant, I have an L92/6L80e from a 2007 Yukon Denali with extremely low miles on it.
Are there any shops in this area handling conversions like this?

Thanks
