Question: Hey Richard, what are the “BEST” stock heads for a turbo LS? Answer: The ones you have on the motor! ANY set of stock cylinder heads can make 1000 hp with the right turbo! You don’t need ported or aftermarket heads (thicker decks do help sealing though) to reach 1000 hp! Run what the junkyard brung!

408 LS Stroker-Triple Cam Shootout Cam 1: 500 lift, 206/214 Dur 114 LSA, Cam 2: 590 lift, 224/232 Dur 115 LSA, Cam 3: 600 lift, 240/248 Dur 114 LSA. Would you rather have the low speed torque of the 206 cam, the high speed hp of the 240 cam or the mix of the two offered by the middle 224 cam? There is a full video up on this test if you want even more info (stock cam was tested too). Make sure to check out @richardholdenerperformance for turbos (grab a 1.21 AR GTX3584RS), 50mm waste gates, BOVs,

Supercharged Throttle Body Test-Stock vs 102 vs Oval Test Motor-Junkyard L33 with @briantooleyracing Truck Norris cam and springs. Some @richardholdenerperformance 1000 cc injectors and @fordracing Coyote blower on top of a @holleyperformance Low Ram and Demuse Engineering adapter plate. The Bigger 102 made a big difference in boost and power, but the oval added only a little more. Tested at higher boost and power levels, the bigger oval TB would show greater gains. If you want more LS power, ch

LS3 Intake on Cath Port Heads With Adapters! The LS3 intake is arguably the best factory GM intake ever made, but does it work with cath-rec port adapters used for LSA blower installs? Anyone else ever tried or tested this? The answer is it will bolt on, but the LS3 intake with adapters makes less power (by 18 hp) than just running a TBSS or Dorman LS2. I wanted this to work so bad back in 2018 when I tested it, but it just didn’t pan out. Get a cath port intake! Make sure to check out the sales

No…I didn’t do a throttle body test on a V12 LS (but how awesome would that be?) For part 1 of What’s It Worth, I demonstrated the power gains offered by a throttle body upgrade on three different combos, a stock 4.8L, a 383 Stroker and a TVS supercharged 5.3L. What is a throttle body upgrade worth? The answer is it depends!
