Indexing Spark ⚡️ Plugs! Does it add power? I tested indexing spark ⚡️ plug electrode openings in every conceivable position including random, toward the intake, away from the intake, toward the exhaust, away from the exhaust etc… The dyno showed zero change in power on the junkyard 5.3L equipped with an @briantooleyracing cam and Fast intake. The EFI LS motor did not care how the plug was positioned. Would it care more with a carb? With a distributor and single coil? On a different engine famil

Twin Turbo Intake! Who you got? Would you rather have an @holleyperformance HiRam and @tickperformance ATW intercooler or a dual-throttle body X-Ram (@holleyperformance or @edelbrockgroup or @performancedesign) ? Which way would you go and why! Make sure to check out @richardholdenerperformance for our mirror image turbos, 50mm wastegates and the lowest price on 1000-cc injectors!

408 Stroker-Single vs Dual Plane Which intake would you choose? We tested an @edelbrockusa RPMAir Gap vs @trickflowspecialties single plane on an 11R-headed 408 Stroker with an @holleyperformance 950 Ultra XP carb. Single plane= more peak hp, Dual= more power down low (but similar peak tq numbers)! I also showed what happened when we added a 250/254 cam-more top end but less down low! Cool stuff. Make sure to check out @richardholdenerperformance (pro tip-get the 1.21 AR GTX3584RS turbo) @afr_he

With a Rebel Yell… Gunna try this @haltech Rebel LS on the @richardholdenerperformance 5.3L L33 to see how easy the install and tuning is! Full vid to come after testing, might even thrown in an intake test or two! You know how we do! I plan to run a Haltech on my Bonneville project as well. All you fools better bow down to the pavement ripping torque of the 1.0L, 3-Cyl, Turbo Sprint baby! | Richard Holdener

This 800-Hp 351W build started by making it into a bigger, 408 Stroker. We then added a big cam, high flow @trickflowspecialties 11R heads and matching single-plane intake. With the @holleyperformance 950 XP carb and long tubes (they were too small) -the 408 just topped the 600-hp mark. We then added a 150 (or so) shot from a Zex nitrous setup. This resulted is an oh-so-close to 800-hp reading of 793 hp. The full vid has even more cool insight. Make sure to check@out @richardholdenerperformance

5.0L Ford vs 350 Chevy vs 5.3L LS How do each of the (near) stock engine combos respond to a 224 (intake duration) performance cam swap? Every bit as important as what they each did is why they did it! Check out the full video up on my channel and thanks for watching!
