Prove Me Wrong! Hey Richard, should I build a 383 Stroker out of my Turbo 4.8L/5.3L? The answer is actually no, you don’t need the expense of the extra displacement when you have boost. The difference between the 5.3L and 383 would be 1-2 psi, and the turbo would ultimately decide how much power the combo makes (regardless of the displacement). In fact, a bigger motor might make less if it gets into the flow limit of the hot side! Let me know ow your thoughts! | Richard Holdener

6-71 383 LS What happens when you run an OG 6-71 from the @theblowershop on a 383 LS? How does 750 hp and 625 lb-ft sound at just 7.3 psi. Yes, that blower will support much more but this was an easy 750-hp blown Stroker LS motor! Make sure to check out @richardholdenerperformance for turbos, waste gates, BOVs, cams, springs, lifters etc… and check out the boys at @afr_heads @briantooleyracing @scatcrankshafts @vortechsuperchargers | Richard Holdener

Looking for that mega responsive Turbo with Right-Now Boost (we call it Quick-Spool Technology) for your junkyard 4.8L or 5.3L LS (or other small displacement V8)? Get an @richardholdenerperformance RHiP800 (GTX3584RS-size) turbo with the 1.21 housing. If you want to run this turbo on a smaller 4-cyl (K-series Honda) or 6-cylinder (RB or 2J), get the tighter housing. On the larger V8s -we like the 1.21! This thing spools on the roll in! Grab a 50-mm waste gate, BOV and boost controller while you

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
