No I sure don't, and if it were me i'd go with someone like Thompson Motorsports, Texas Speed, etc...

We have several 408CI options and keep many of them in stock and ready to ship. We also have a 1 year unlimited mileage warranty with a starting price at $3849.

I have used them. I have a performance shop and we have used a few of them actually. I had them build a Forged 408 about a year and a half ago for my daily, and have had no problems at all. It has been boosted from day one lol. Brandon is an awesome guy to deal with and the prices are hard to beat. Brandon emailed me pictures of the build process, and was in contact during the entire time. I wouldn't use anyone else for my customers or myself...top notch

Feel free to check out my build.

I purchased my ls408 from brandon as well. EXELANT customer sevice. Short block arrived quickly as promised. Had have absolutely ZERO issues with it so far and I beat the dog **** out of it lol. Its built for boost but havent put boost to it yet. I have approx 3-4k miles on it. Shooting for 1000+hp here in couple months.

I recommend atk for sure. Top notch quality. They also painted my block for me and sent pics as it was being built for my portfolio.
