Huge shoutout to Trick Flow Specialties for helping us out on this build! Be sure to check out everything they have to offer here: www.trickflow.com Also a huge thanks to @enginerehab for taking the time to come and join the discussion!
I actually worked for Rottler Mfg and designed cylinder head clamping attachments for the Rottler SG10XY for Trickflow to accomodate about 10 different Trickflow cylinder heads.
Those of you that aren't machinists have no idea how bad ass that hand deburr was. To do that without the cutter getting hung up, AT THAT SPEED, is insane.
I'm not a professional machinist ('lectrician by trade), but I do have a few manual machines (I have enough experience to consider myself an entry-level hobby machinist), and I was absolutely floored at how quick (and accurate, I assume) the tech was with that die grinder!!! Talk about skill!!! 👍
Mhmmm!! Anticipation, there's a reason Jim has the Heinz bottle in the shop. A bloody teaser for folks like you, patiently (impatiently) anticipating that first drive with this unique 383!!
WOW Scanner Danner you got the hook up going on here! I'm guessing by your multiple(8 -10) comments on this video alone that you're pretty damn happy & excited with the progress coming along well. Can't wait to see this back in the Ramcharger flying down the road - or standing still spinning the tires off the rims! 👍🏻👌🏻⚡💥💨💨🚚🚛🚦🛢️⛽🛑🚧
This episode was so good! My favorite so far, in part because we are seeing it come together and also all the nerdy stuff just speaks to me. 😂 Nic, you were so wise to bring Josh in! What a wealth of information he is, well spoken, easy to follow and clearly knows his s***. Thank you both so much for taking such good care of me. This whole project is the coolest thing ever. I feel blessed.
I spent 3 grand on a set of ZL1 heads back in 1972 . Got the whole 9 yards, but these heads you had built put mine to shame. That was a lot of money back then. Trick flow heads are a steal, I wish they were available when I was running.
This is so interesting for me. I see JAMSI, Scanner Danner and Trick Flow come together before my eyes as entertainment and science lesson both. At that, their businesses complement each other. The relationship of TH-cam viewers to this event is valuable to all three parties. This sort of affair can never have come about when I was a youth. This internet is a fantastic affair! I hope that cut out in the cylinder bore for the valves is OK.
I agree and I really didn't see how truly awesome this was going to be going into this. Blessed to be the recipient of this soon to be bad ass engine too! Glad you're here and following along!
Just recently we had a 494 BBM on the dyno that made decent numbers for a street pump gas engine 600+ torque/500+ HP but after our requisite post dyno compression test I had some variances I didn't like. I did a leakdown test and had 3 cylinders that had about 30% sealing (yikes!!) with most of the leakage going to the exhaust. This was a typical "offshore" aluminum head. We pulled the heads and recut the seats and the seat runout was horrible on several of the valve seats. Upon reinstallation it picked up 12 to 15 numbers across the board. That was a big financial hit on something that is sold to the public as a "bolt on" item. Enraging that shops have to spend money on "quality control" that can't be billed to the customer. We've used a couple of sets of the TFS BBM heads, and they are very nice.
Watching your video was a pleasure.It's always nice to see when people care about the quality of thier WORKMANSHIP. Accuracy as in size and fit,and close tolerances.Also cleanliness of parts and work-space.It's like watching a batch of milk,when you can see the cream rise to the top of the tank.thanks guys.
Dropped into comments to upvote what I knew would be here -- I just watched 45 min without skipping or 2x and honestly was in that video space as if this was lord of the rings or something.
This was an exceptionally interesting video. I recently bought a set of trickflow heads for my future replacement motor. I knew they were really good, after these explanations I appreciate them even more. This was a great collaboration, thanks.
No mention of the Harland Sharp rockers. Good rockers been using them since the 80s. A great in depth video. Great info on spring and retainer application and weight savings benefits Thanks
Budget, not satisfied with boxed Holleys, is how Barry Grant got started. He modified the heck out of Holleys trying to improve them. All started with a big block Chevelle in his one car garage. Eventually he quit his day job.
I bought a set of Brodix track ll heads and paid a pretty penny for them and I always put water with food coloring mixed together and dump into the exhaust and intake ports and they leaked rite out of the box , for $2800 I was a very pissed off customer I called them 20 plus times just to get them on the phone and the guy I talked to told me that's what I get for $2800 so I'll never buy that brand again, I took them to a race shop to have them fixed and changed the valves they told me they should have never been boxed up and shipped !!
Preet cool video today with TrickFlow! I just watched @Daves Auto video about heads & how hes fixing up brand new aftermarket manufacturerd 6.4L powerstroke heads and how they need to be checked & 'fixedç right out of the box. Now im on your video wathing a much higher end manufacturer billet aluminum full CNC machine heads being put together! Must be 'head day' on the channels today! Anyways lookin good & @SD is getting excited along with all of us along for the ride. Lets see this thing breath some air, & come to life shooting fire!👍🏻👌🏻⚡💥💨💨⛽🛢️🚦🚛🚚🚧🛑🤔
16:42 It's funny that you mention how bad the diesel heads are... that's the same thing Dave had said in that last video I just watched. I guess it is in fact a common issue with the aftermarket diesel head\machine work.
32:22 @CEE used a real yellow 'banana' micrometer in their last video on Friday too. What's going on with the banana 🍌📏 measurements these days? 🤔🍌📏🍌📏🤦🏻♂️
EXCELLENT! Thank you very much. I was hearing about this stuff years ago and it all sounded very arcane but I could grasp the benefit of flow, so now I have been enlightened.
Men, i don't know that much about proformance engines but heads like this for $3,000 with profomance springs, and valves installed so that it bolts right on (without additional modification to fit) the block of choice seems like a hell of a price.
Excellent follow up video ! I am a Mopar guy but the cost has forced me to go to the poor mans brand ! So Chevrolet it is ! Never should have sold my Hemi Barracuda ! Thanks for sharing !
Super informative in every way. I’m building a AMC 360 for my 77 hornet amx . I did some port cleanup and port matching on the iron heads. .045 piston quench, roller cam and other mods. I’m only looking for 400 hp . I call this the practice motor as it is my first build.
Nice video Stock Mopar big block heads are notorious for bad airflow compared to Fords and Chevys. These heads are a great alternative Nice quality. Can't really wrap my head around an 11/32" valves, but I guess they know best
They have came a long ways! Nice to see a single point cutter for the valve seal now! They used to use a rottler and I have a few sets that were absolutely terrible on seat profile and seat run out
In the middle of this video I researched their SBC Twisted Wedge heads. I was considering them for my last build, 20 years ago. They were not available. I now know why. Keep up the good work.
Twisted Wedge heads were designed for the 85-up Mustang 5.0 engine. They changed the valve angles to allow for bigger cams without having to flycut the pistons.
Nice video. About the short turn on the original heads, mentioned around 22:50. I recall a Toyota discovery that having an angled intake port caused a lot of air swirl in the cylinder and massively increased efficiency. Looking at the original heads those intake ports seem to have quite an angle to them and maybe that's why they made good power despite the short turn.
Jaime is Definitely a ... BLACK SABBATH fan !! 🤘🤘 .. close guess on the Beatles. ... Also, really looking forward to the progress on this build. Very cool. 👍
You people do such interesting Machine Shop Work, I'd love to work for you. I would love to learn more about machining Automotive parts. I am a Manual Machinist, now retired, and the work you guys do is in the Manual Style of machining skills. I sort of imagine that the bulk of your shop work is Customized due to the various Engine makers and the jobs that need to be performed on them.
"what really matters when it comes to product quality is, do the guys who are working on it actually care?" Words to live by, in virtually all fields of endeavor 😊
Trickflow makes really really nice stuff. that RA isn't just due to the machine process, it is also the quality of the casting. you need a really rigid casting, with good material and properly heat treated for a good RA. Be nice if we could get heads made out of hard aluminums like 7075, man it is super easy to get a good finish on 7075. IIRC trick flow uses heat treated 356 T6, machines nice, hold shape well, fairly hard.
I always thought that the ports were polished to mirror like finish. These look very rough. Perhaps it a golf ball dimple effect that improves a laminar flow.
This is unrelated to this video but you made a video in the past about cleaning engine parts. My question is, does cleaning in a similar manner to your process, ie. baking, blasting, washing, and the steelabrator do any damage to valve seats ? I was told this was a possibility by a local shop. I’m rebuilding a set of 390 Cadillac heads somewhat on the cheap and I need them cleaned well, but the seats and valves are all in good and reusable shape in my opinion and I don’t want to have new seats installed.
I would be a LOT MORE EXCITED if this was being built for ME! But this is still very interesting getting to see what is possible from a 413 block. IMO, aftermarket heads are the way to go IF you can afford them. you can grind in those stock heads for weeks and NEVER even come close to what can be achieved with heads MADE for performance, rather than pushing a 5000 pound brick down the road.
I usually work on V8's, and other larger engines. Ended up working on this really small engine that had dropped a couple valves and wrecked the chambers. So, had to replace it as it wasn't machinable. I called around to all the local wreckers, but after asking them how much they'd charge for a little head - they all hung up on me! :D
A great finish... We had a Italian Berco surface grinder...wet, them dress them stones... Back in 1980... It put a better finish than 18 micro inches Ra.. With our SJ-210 now which wasn't available then... The Berco does like less than 10 micro inches Ra... With another grind stone....almost mirror finish... So long ago. I hope they still make the Berco. I hope so. I could turn it on...dial 0.004..let it grind..while I go grind seats with the Sioux Yeah we had that other head tool.. Float table...form tool WC three angles... And I never played that 1 degree offset game like some factory grind... Isn't it amazing...exhaust guide clearance like 0.035"..for say a 2" valve the worn engine can put out great power What up with that ? Anyway it was nice to see the folks care and so do you about the head machining... How about better material for the valve guide..? Isn't it shame....this engine is going to throw a rod... Or be just a little lean...or have some ridiculous valve lift...few cam lobe will break down...and there goes that coarse polish powder thru the whole engine. All to make the TH-cam audience have to see a big dyno number. Sure- I love the power. Can it match my good ol 7.3 IHC? 463K miles so far. I do change the oil. I am thinking she might ready for a new set of valve springs...just a loaf along engine. 300 hp down low...good enough for me. Oh yes back to the racer...yap pour on the nitrous Boom...suck that exhaust valve. Poor Trick Flow Head I like a set. Oh too bad...not for my tractor motor..
@22:00 the new head looks significantly wider on the intake side. Talk to me about this Nic or Josh and how is the intake manifold going to fit? OR I'll wait for the next episode!
Wouldn't you want a stronger valve spring to reduce the risk of Valve float??????? OMG this stuff is beyond me and thank you sooooo much for this video as it gave me a better understanding of a custom build and especially the flow characteristics of cylinder heads.
Years ago did a full top end build for a guy with some trick flow heads and omg the quality of those things was too good for the body but race car things right.
I don't quite buy the reasoning that you're putting on more force on the springs with larger rocker ratio. It's a lever so it's the opposite, force goes down but distance and speed go up. Kinetic energy is what matters, and acceleration, and on top of that all kinds of vibration leads to loss of kinetic energy. But basic formula is half the mass times speed squared, and can calculate kinetic energy. Lighter springs make sense as they sap less power from the engine, and stress rockers and pushrods less, so you can go lighter in the whole train as well.

4:50. They use butter on their valves instead of ketchup!

They should do any filing or deburring with the surface tilted down so any material removed falls away and not down into the valves.
Have you looked at the golfball dimple pistons yet????
I had a set on mustang. I loved them.
Looking good!!
Great content and thanks 👍🔧
I'm looking for a head set up for about .750 lift, does Trick Flow make a head with larger flow capability?
Wouldn't you want a stronger valve spring to reduce the risk of Valve float??????? OMG this stuff is beyond me and thank you sooooo much for this video as it gave me a better understanding of a custom build and especially the flow characteristics of cylinder heads.
Those ARE stronger springs, but lighter.
@@hotpuppy1 yep, he mentioned like 60lbs or something like that?
Probably the best factory wedge head for Mopar's was the Max Wedge or the 300J heads....
Thanks for sharing 👍
show us clips of your efforts running!
In your opinion, is there such a thing as too smooth of a gasket surface?
That ws very educational.
Fascinating!
My first set of aluminum heads were sbc EdelBrock rpm back in 1990 when they first came out i think they $825 from RHS
Suggest a poster version of the valve to cylinder wall clearance shot at full open.
Years ago did a full top end build for a guy with some trick flow heads and omg the quality of those things was too good for the body but race car things right.
34:00 its an alien with glowey eyes!
I don't quite buy the reasoning that you're putting on more force on the springs with larger rocker ratio. It's a lever so it's the opposite, force goes down but distance and speed go up. Kinetic energy is what matters, and acceleration, and on top of that all kinds of vibration leads to loss of kinetic energy. But basic formula is half the mass times speed squared, and can calculate kinetic energy. Lighter springs make sense as they sap less power from the engine, and stress rockers and pushrods less, so you can go lighter in the whole train as well.
