Who wants to see a draw-through carb M90 test? Who wants to compare Carb vs EFI? Who wants me to run both? Well…. You are in luck, the vid that just dropped has all that! Typical EFI M90. Rear-mount Carb on an elbow feeding the M90. Then combining both to dial in the AF mixture! That’s a lot of cool in 1 video! | Richard Holdener

Carb cams! Does a carb LS need a carb-specific cam profile? I’ve run stock cams, mild cams, med size cams and big-boy cams with carbs and guess what? They all worked! Match your carb cam to the effective operating range of the intake and you will do well! I have plenty of carb combo videos (of all engine families) up on my channel. In other news-We just installed one of our $100-off sale cams (Truck Plus) in the Turbo Tahoe (not a carb motor) and already got some dyno results. Look for that full

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

Finally, test data on the RHPE 8.1L Stage 1 cam! Working with @elgin_industries , we found a cam that adds 30 hp and a like amount of torque (adds power everywhere) compared to your stock 8.1L cam. In the new vid, I I compared it to the bigger ZZ502 cam (which is a touch better on top). I also compared the @dartmachinery dual-plane, carb intake and @edelbrockusa 850 VRS carb to the EFI intake. So much cool stuff! Go check out the vid on my channel. | Richard Holdener

Richard_Holdener on Instagram: "575-Hp 5.7L LS1 Carbs vs EFI This test was run on a heavily modified 5.7L LS1, equipped with a big 239/255 cam, @mastmotorsports CNC heads and @holleyperformance Hi Ram. We ran the modified LS1 first with a pair of 1000 cfm, 4-hole throttle bodies and port EFI, then with a pair of 650 Holley HP carbs. Spoiler alert-the charge cooling from the carbs made more power (airflow was not an issue). Looking for more LS power, check out the turboie goodness over at @richar
