Use the promo code "ALWAYS" to get $101 off.... no idea when this sale will end... but this block is cast from a better grade aluminum, also rotocast (shaken to get rid of bubbles... therefor denser), billet main caps, piston squirters, 13mm head bolts (All other LS are 12mm). This can be run wet sump or dry sump. They are normally around $3700-3800! Of note- You can't run a stroker crank with the stock piston squirters; however you can if you install the Katech squirters if you go that route. ($80/each)
I just bought one for my Chevelle to build up a bigger turbo motor.... That GTS76 turbo (1200hp rating) will like .9 more liters for faster spool (vs. the current 5.3).
