Richard Holdner just dropping knowledge . Love this channel.

Hey, the Speedmasters did better than I thought they would, God knows they're cheap.
Now the AFR 265 heads I had never even considered, don't know why, those are some real tire shredders.
Thankyou Mr. Holdener.

100k subs coming soon! I've never seen anyone do such thorough testing like this, definitely learning a lot thank-you!

[FreakOlds]

Good one 👍🏻
I’m running a set of the Brodix RaceRite Ovals. They’re awesome on my 468. I’ve run 11.8’s at almost 4000 pounds with tall tires 3.73’s on pump gas. That’s with a dual plane intake too.
I especially enjoyed this video!

Mr. Holdener you are the hardest working guy in this business. Thank you.

Holy cow Richard, I work up a sweat just watching your videos, I can't even imagine how hard you work, I have an engine shop, and dyno, So I know first hand how much work it is to put an engine up on the dyno..>> When I first started my shop a thousand years ago, I "fantasized " about doing just testing, and experimenting like you're doing, good luck, turns out, there are stupid bills to pay, so rarely do I get the chance to do experiments like you do. 1000% respect for your hard work.

Richard. Your channel is CHANGING the game. All other channels are in your dust when it comes to videos packed with information.

Nice test. Thank You. I don't even look around anymore. I just purchase the Edelbrock RPM kit for my Big Blocks and put them together. They run phenomenal.

[UnityMotorSportsGarage]

Dude... The amount of testing you have done never ceases to amaze me!!! Great Job once again! Keep them coming... And I'm ready for a Shirt...just saying!

[fntony]

Alright Rich!! I am ready for the BB Rect port test!! In the way back, 1995, My 496 had Cast Iron Merlin Rect Ports, 850cfm on a Vic 454-R and Comp Cams 288AR-8 Solid Roller, with flat tops it had 9.8 CR 605hp 610tq. Peak Power at 6400rpm. I always wanted to improve on that but never had a chance.

[AJsSpeedShop]

Goes to show you, flow numbers don’t always mean shit... AFR 265 with the smallest ports, smaller valve etc dominated the group. Most power, best curves, held on the longest up top. Killer stuff Richard.

I can’t wait for the rect port test.

[JackLawson-WingSmallForward]

Great job and fantastic information Richard!! Thanks you for these tests. Dr J's did a great job porting as they created more HP than some aftermarket heads. Well done!

[peaceandrelaxationwithgodscrea]

Richard you have the best job in the world. Thanks for sharing with us

[MississippiDan]

Awesome test!! Building one now and was trying to pick a head... ❤🙏😁

[lukemorgan]

The dislikes on this video must have got their feelings hurt by old school big block power at the stop light 😂. Great video!

[oldschoolbudgetracing]

I have been a major advocate of oval port heads on a big block for years. Love proving people wrong with the oval ports... lol

[Trebor-gwlt]

AFRs were no surprise. Best out of the box heads that you can buy.

[steveblottenberger]

Keep up the good work Steve from Annapolis Maryland you're like my double

[stripes]

Great video with lots of information I have been looking for. Thank you Richard
