SB Cam Thrust Plate P5249637 no longer made? Only tensioner now?

That's some serious business there. Even if my numbers are way off you should be at 550 or so. Any dyno's close by?
Yes there is one but not going that route. My plan was to build a mid to low 10 second car. I approached the goal as a whole. Motor, trans, car weight, big tire,etc. 14x32 tire, low gear 904,aluminum rollerized trans,4:88 rear gear. Total package. It is still a bracket car and will run what it runs.
