Hi, the injectors i used were bosch 280 150 901. They were the longest i found. To get even more depth i had to cut the injector tube/sleve that sticks out of the head, level with the head and machine the body of the injector above the o-ring seal so it would fit inside the injector tube and allow the seal to bottom out. This then allows the tip of the injector to be level with the inside of intake chamber so the injector isn't spraying inside the injector tube. These injectors were off an Australian 3.8L GM car. I believe the same engine may come out in a Buick in the states? Will post some more pics when i get the intake and supercharger mounted. Cheers Nick 10927 can you give more details/pictures on the injectors??
