Has anyone heard of this company and if so have you used them are they worth the price I found on gm parts direct a lq9 for just a few hundred dollars but not sure if if it is complete turnkey or just a long block if you have any info on bd it would be much appreciated

 

I just bought a 5.3 with ls6 cam from BD. So far I am very pleased. The engine came with allcthe accessories and computer hooked up. The wiring harness was modified for 3 wire hookup and the computer was tuned for my build. And best of all, the engine is CLEAN. He even cleaned up all the wires. I'm just collecting a few more pieces before I can swap it in but for the money ($3,400) I have a 360 hp motor that is all prepped for my swap. I'm putting it in a k5 blazer, so having the wiring hsrmess already modified and tuned was a big selling point for me
