my block from SBR did not have a block off plate for the front balance shaft on the block. a buddy of mine had his block built by buschur and his block had it blocked. i called SBR and one of their techs tells me that they only supply the bearings and that (since i purchased the BSEK from Mach V) the rubberish cap i got should cap off at the front case cover. at this point i still have the front shaft in the the block per VFAQ. no belt along with the stubby shaft installed.
