I have heard from a lot of peeps here who have broke caps on the low deck. The bcr caps and girdle are very nice looking pieces, but that price would push me a lot closer to just getting an aftermarket block, which is out of my price range. I am honestly just trying to figure out the best bang for buck. Honestly I could probably meet my goals with a 451, but then I feel the victor max wedge ports are a little large for a nice power curve with that size of motor. I do want a 6500 power peak with a 451 or 470. But then the stroker kit prices are tempting for the 440s but id still rather build a low deck.
