360 short blocks

I dont know if they are good or not, I'd think they are, because of Summit's availability..Not that the date's accurate, but if they were axed, Summit wouldnt keep any delivery date. Mancini has a 360 short P5007549 (Magnum version, hyd roller cam, etc.) in a clearance sale ad on the site..$1300. Personally, I'd question that purchase like the others did...
