Has anyone heard about the SFI approved blowproofs that Mitchells are having made for the 4500 and 5600's? When will they be out? Can't wait! Two weeks ago I was at a meeting about pulling in the Interstate pulling circuit. A couple guys were ****** about a diesel smeering all their 500+ci gassers and looking for reasons to keep them out of the 6200 and 6500lb class, and not having a blowproof with a manual transmission was the only thing they had..... Can't wait till spring, having to many friends can become annoying
