1000-Hp on Pump Gas? Loaded TWO vids today that covered ALL testing I did with @stevemorrisengines recently. We compared the stock LS3 821 heads to the new @afr_heads 275 LS3 Mongoose heads. Tests were run NA and Boosted on 93 pump & E85! Also tested a radiused air horn on na and supercharged combos. Any guesses how much timing Steve ran on the @vortechsuperchargers motor? So much cool stuff! Make sure to check out @richardholdenerperformance for deals on LS turbos, cams, springs, lifters, waste
