Edelbrock Performer RPM heads - let's see if they are any good???

[@danwiththe8647]

it's shocking to me that these videos are getting such low views. this is INCREDIBLE knowledge being passed on here

[@johnflett2531]

Don't be surprised, DV tells people what they NEED to hear to make horsepower not what want to hear. Most people want to be told hard, fast and simple rules on how to build hp, they don't want to waist time all the details. I know a guy who has built many high performance engines and he told me that putting larger valves in a head kills torque output. He told me he's done it before and it always resulted in less torque. I tried to tell him that you haft to do work to the rest of the head to make the change pay off and he just said "diesels use small valves for a reason". Like I said, hard, fast and simple rules.

Not shocking to me. This is highly esoteric information for a niche market: old school pushrod V8s in the age of electrification. Like it or not, kids care a lot more about social media and video games than cars. We are the last of our kind. Kinda like ROCK stars. 😕

I am begging Edelbrock to please continue to produce the FE CJ style cylinder head. The overseas companies cannot compete with the quality of the FE heads that we have worked with for years. I can’t port iron anymore. But I can port aluminum. I really like the fact that the castings are generous for porting. I want to be able to shape the CJ port to accept a 2.165 and 1.65 with a generous amount to be able to bowl hog to the valve diameter and to be able to cross the flow away from the bore wall. The Ford engineers really knew what they were doing designing the FE and I really hope that Edelbrocks FE Ford heads will maintain their great power production!

[@annmarierudolph2291]

You have over looked a very important area i purchased two pair of performer RPM #60899 from Team C performance in southern California and prior to installing them on the Engine i noticed that the pushrod guideplates did not line up with the cylinder heads. After calling the so called hot shot at Edelbrock and had no help from them i decided to take matters into my own experience i looked at isky adjustable guide plates then i saw a piece from Jomar there unit had a greater range of adjustability part #1501 Edelbrock supplied guide plates installed more than half of them would not even let them go in the heads you spend a lot of money you would expect them to work! Im not a amateur mechanic i have 55 years experience and have built many bracket engines the cylinder heads you demonstrated are old first castings i purchased them in 2021 newer ones darts are no better unknowing people still grind out guide plate slots and other horrendous acts of butchery that are catastrophic in the no so distant end Please pass it on dont forget!

[@jimlathrop8603]

Thanks, I keep learning more and more from your videos. Most of the cylinder heads I've seen you work on have similar port to valve angles and therefore similar bowl work needs. In a future episode could you work on a head with a steeper port angle so we could see the difference between the flow through the bowl area and into the combustion chamber. How that effects deshrouding ect.

Great video David. Like to see how you polish finished those ports and a compare on predicted power and torque gains from pre working those heads.

[@lewisbrodnax2682]

I'm not in any position to ignore what is, obviously - the best damn shop talk video blog out there. However my interests are limited as are many others, to what I have that needs to have some TLC fromm me. Because it's not going to be given what attention may be needed from anybody else. And like many others I have a real hard time getting the information specific for my problem. Specifically, I have a GAP 1986 Chevy an...with a 305 small block. It's never going to be even close to the '69 327 Camaro I used to have. Worse yet, I'm in California. That car had the The 'Fuely ' camel hump heads,1.94" in+ 1.50 ex , but the solid lifter Duntov cam. LOT'S of suicidal fun...but nothing that I learned then will help me now. Where's any good, and DIY oriented info to do a decent 305 SBC. build? Thank you for all of this,every thing you say is priceless.

[@jeffrykopis5468]

Mr. V, after your successful porting of an aftermarket casting, do you ever help create a CNC porting program for the manufacturer to replicate your work? EDIT: Imagine being able to bolt on Edelbrock/Vizard heads. They already have Glidden Ford heads and Pat Musi big blocks.

[@christiannelson7899]

I found interesting a couple things you mentioned improved low lift especially. I would be interested in some specific mods to do to improve low lift, or mor mid to low rpm operation. I want low end torque, and good fuel mileage, with cam that will be long lasting so it isn't pushing limits of the valve train, on an engine that will rarely ever go beyond 5k rpm. Say a 305, 307, 283 displacement. Not looking to get 500hp, but mor like close to 300 ish. Your mission impossible engine seems like what I am looking for. Great stuff!

[@ggdragu6013]

Thank you for all you effort of educating us with your knowledge and experience. Although I'm not even close to working on V8 engines or tune them, this is very interesting and many of the principles you are showing here can be applied to almost every engine. I'm more into small diesel engines tuning/performance and I have some questions regarding how does boost affect the flow of a port and how does it affect the valve train, the spring to be specific. The basic instinct tells me that the more boost you run, the spring will have more resistance when having to pull up the valve. Is that something you can calculate/measure? I'm very curious if you have any input or a video on this. Greetings from Romania.

[@HectorFabela-m4y]

I have a question or two. 1. Would this be for NA or boosted? Or both? 2. Does this do anything for a towing application? 3. What would be best for a BBC 454 for towing?
