Bill it is a 487 Iron block Stage 4 Heads . The converter is a tight for Nitrous. We were going to spray with a 150 kit .
Bruce , the track was so cold & slick that day as you would kinda expect 46 degrees . I heard the tires squealing every time about the 330 . At the end of the day we made the 9.03 pass . As the front came down and leveled off the tires spun . Brandon was in the air while shifting into second at about 6700 rpm . We had to loosen the front to get it to hook . Any tighter it knocked the tires off . Trap RpM was about 7250 . We have to look at the computer to see exactly where we were at . We were just so excited we didn't care to look . Lol . Look into the video of the big wheelie on FB . The video from the computer you can here the tires spin . Nick
