I own Weingartner Racing LLC. I port cylinder heads and intake manifolds for street and race applications. I am based out of Broken Arrow, Oklahoma. On my website www.wengines.com you can see the products mention on my channel. Phone number is 918-520-3480
I'm from Texas and have a pretty serious southern drawl. I say I talk like cornbread. I'm a big fan of Daniel's channel, and this one too! This cam challenge is genius.
Great info love the channel. I have a question How do you learn where the cam events should be? Any books or software? I have read lots of stuff and have watched lots of videos and I understand how it all works but I just cant seem to figure out how you calculate the exact degree for the events to accomplish the goal. Hope you get what I am saying. A post above said something about Vizard having a formula and being the only one and Powell replied he's not the only one so where do you learn these formulas. I want know how to calculate the cam events for any engine. I get that its probably a close guarded secret but any help you can give for how to do it I would love to hear.
I hate that intake to exhaust ratio crap... it started out as a rule of thumb, and somehow turned into a rule. Then Pro stock demonstrated how stupid that rule actually is. The reality is whats the damn application!!!
With only a few horsepower gain from the AFR Enforcers, I would keep the stock heads and do a little porting to them and save some money vs buying the AFR Enforcers. I know everyone has a budget, but to me, those AFR Enforcer heads are greatly lacking and not really worth it for such minimal gain. 😐😒 If I am going to buy some AFR heads, I would rather get their fully CNC ported version ("Magnum" ?) line of heads if I had the money to spend for them vs the AFR Enforcer line. I would think their fully CNC ported Magnum heads would really kick some A.
Gerald Brand, seems like a good guy, and I hear he does good work, but I wouldn't have him repair an aluminum or billet block after the video he put up say a year ago.
TRICK FLOW SMALL BLOCK MOPAR heads. I just bought a set. I was wondering if you ported the set you did a review on. And if so, what gains did you see. I appreciate the all the great info. Take care.
I'm just wondering could you do a "Leak Down" on the motor @ the Start then the Finish? I kind of think it might wear itself out .....Just thinking strange thoughts here.....I'm a weird guy! I once spent 10 hours porting a set of Corvette "Rams Horn" exhaust manifolds to make a "Stock Appearing" Corvette run mid 12's through the factory exhaust system.....😁
I wish UD Harold was still living... That guy was a genuis with cam designs... So much that several cam companies who i wont mention used his designs and tried to claim there own... Then after retreving all his knowledge fired him or made a reason to get rid of him . Alot of his cam profiles were us in alot of winning cars....
Yes he was! and would talk to lots of people....There would be no Comp Cams without /harold all their stuff was designed by him in the early days. I still use a few UD lobes on my builds and Bullet Cams has all his old "Cam Masters" in their inventory.
@@ejgrant5191 The Same goes for Lunati and bullet cams. Harold work for them as well before he died. He started with ultra dyne cams if my memory serves me correct.
What is more important when selecting pushrod length, having the roller rocker tip centered on the valve or having the rocker perpendicular to the valve at half lift? I have a SBC with Trickflow DHC heads that I set up for perpendicularity but the roller tip favored the outer edge of the valve. It recently seized an exhaust valve in the guide in only a few hindered miles and I was wondering if that was why.
It would be interesting to know what machines the cam grinders are using. Whether it's the old style Burco or Vulcan machines or the newer Landis style CNC machines. Powell.....yeah. You've got to understand "redneck". Not an insult by any means but he definitely has the slow southern drawl!!!! Hella sharp dude though with a TON of smarts to share! Thanks again for what you're doing!
Just want to let you know: I think you and David Vizard are providing some of the best, honest, valuable information to people who actually want to learn, and find answers. I'm 52 now, been into cars and engines since I was a kid. Best 2 channels on you tube, if you're in to making power per dollar. Hope to try a set of your ported heads for my next build assuming the world doesn't explode first. THANK YOU, TO YOU AND VIZARD!
the thing about Forums is to many dyno jockies in the real world Ets are more realiable horse power being more hollow torque actually ruling when i see dyno sheet i picture a hot wheel staying on the top line weather it be torque or hp thats the way the race will go
Bought a set of these the first month they released. They had a few loose guides, and a few broken guide plates when arrived from jegs. The exhaust ports are so misaligned with the bolt holes that I had to modify the headers, even though they were supposedly compatible with 1 5/8 headers. Anyways, bolted them to a 383 stroker in an 81 camaro, with a 4 speed manual, 3.42 gears, 3400lb race weight. 12.33 @117. Not bad! I wish I had bought different heads though.. That was over 20 yrs ago.
Hi Eric Have you ever ported a set of V8 AMC heads ? Both Edelbrock and Indy have aluminum ones for AMC If you haven't ported any would you be open to it ? Greetings from Iceland
Post 90's, it seems to me that hospitals do alot of patient [wallet] farming - minus the charity that used to occur, handling poorer patients that once made a decent balance. Simple, even dumb things like carbo loading [serving up a zero protein meal] to the bedridden, or mucking about with stents when a patient clearly is on a path to open heart surgery come to mind. Doctors are in charge of their own offices but the moment they step into a hospital setting, administrators are largely dictating standard of care. Some of them suck, and most of them... are practicing cdc, not medicine.
Question: When porting a n/a cylinder head for a limited intake valve lift application. Like performance street or endurance racing. How do you determine the CSA relationship between the curtain area and these other key areas of the intake port. " Throat%, bowl%, and pinch or minimum csa. Say.... 2.08" valve with .550" net lift.
My question: Let's say you have two ways to achieve a target compression ratio and one involves a larger chamber and a flat top piston, and the other way is with a smaller chamber and a dished piston. Is one scenario preferable to the other? Thinking about a chevy 383
I believe everyone should have turned in their timing cards within a specific time to not give anyone time for trial and error, to see what they have right out of the top of their heads
I made it to the end! You don’t port cast iron heads! Yes, I subscribe to both yours and Daniel Powell’s channel and he is DEFINITELY a cool dude who knows his stuff!👍🏻 As a matter of fact, I’m planning on contacting him for my next camshaft. And btw- I’ve said it before, but this camshaft challenge is great, so thanks for doing this HUGE undertaking, and yes- I donated.👍🏻

I’d like to know how much power a 3” collector can support. This would be for a 1 7/8 “ primary for a stroker small block Ford Cleveland. Just wondering when you need to step up to a 3 1/2” collector and bigger primary. 2” is common for Cleveland’s.
I am a Canadian and I watch Powells videos just to listen to him talk. I wouldn't want to piss him off too much as I believe he could snap you in half without breaking a sweat! He is very head strong and doesn't like to be criticized. I guess when you learn from your own experience, you want to protect that. I also like Brent Lykins and hope he wins. A Ford geneous, designing a cam for a GM engine should be Interesting. Thanks, Eric for making this happen. It takes our minds off of Politics for a while.
We choose our cams on timing events that produce the best static compression ratio for the intended application. Like NA, Boosted, Roots Blown, Nitrous etc.
Its great that you are doing a little blurb on each competitor, its very interesting to learn a little bit about each person and if they have a U-tube channel, chances are they will get a boost in viewers. My question (which I think you may have covered in another video, sorry if you have) is it just a myth that running bigger-port heads than theoretically ideal results in a drop in mid-range torque due to a lower intake-charge velocity. Thanks for the great content!
Hey Eric, made it till the end as always 😂😂😂😂😂 This is a question that goes way back to what an engine builder told me prob over 25 years ago. He said he prefers to use cast iron heads on cast iron blocks, and aluminum on aluminum if you can get a comparable cast iron head say dart iron eagle platinum to its aluminum counterpart. The reason being is the growth rate varies between iron and aluminum so it's better if they can grow the same. I may not have worded it perfectly but hopefully you can understand what I'm talking about, thank you. Do you agree????
