I drafted a hemi head for the slant six in the '90's for fun. Man, if I'd made them, can you comprehend how much money I'd have made since then?
Less than I actually made, since then. That's how much.

No,....but by talking about them, especially for the Slanty, enough interested people may end up coming to more of a consensus on what it ought to be. When that occurs, there may be broad enough interest for someone to pull the trigger. Right now a cross-flow hemi-style etc. is not going to be a winner, it just ain't, & I would like those who insist on it to give Me a valid technical reason why....other than simply un-shrouding the valves.

i'm sure the great minds here can come up with a great head. but its the tool and die and costs.
then at what price does it make it feasible that alot of slant6 guys would want it.

Mopar guys are cheapskates. Nobody would buy it except for the rich elite that have money they don't even know about. Mopar is a niche market to begin with. Narrow it down to just slant six stuff. Most guys that have that kinda money wouldn't look twice at a slant, so now you're talking about an even narrower market. It's not gonna happen unless some rich dude with a machine shop just gets bored and decides to do us a favor. In other words, it's not gonna happen.
 
So whats what a good price, lets say head,rockers etc. bolt on. head flows great, better performance, mpg's.
and its lighter. would 500. for head. sound crazy?
 
I would think if the head is a very good improvement from a stock head that 1K would be a price that would sell.
 
Cross flow hemi can get larger valves in there. Would need pent roof pistons to boot. How about just a mod to get us taller ports? Cross flow exhaust on passenger side, go to a Distributorless ignition system (EDIS, crank trigger, etc) and remote oil filter to clear up the passenger side and you'll have plenty of room for some hemi style downward pointing headers. Some college CNC final on the 5 axis Okuma with 2 billets of Aluminum, make it 2 piece: top and bottom with routed water passages between the 2. Send the finalized part to China and have them cast 1000 of them so you can get your tooling cost back and make a profit. Just make sure you look at the first one very closely to see if its worth a flip. Sounds like something Dutra could get Clifford to back. Youll probably sell 100...at $800? Edelbrock make a 4.0 AL head...$1500.
 
years ago i had an original a12 dodge i was trying to reproduce the aircleaner. it didn't work out. but someone did.
At the time i assume alot of guys with a 6pack hood scoop would of wanted it. Only problem he was asking 1500. each. so that narrowed the field to about just a12 owners. never knew how many he sold!
 
An aluminum cylinder head for the Ford 170/200/250 six is $2250. This includes valves and springs. A head for our engines would be around the same price.

Maybe the guys over here will build you one https://www.vintageinlines.com/ they already did one for the Ford 6 banger.
 
An aluminum slant six head is not going to happen. The number of people with the money, time and energy never did reach critical mass and the number of interested parties shrinks by the day. I road raced a '66 Dart with a 225 for a while in the late 1990s. I got tired of trying to build a decent oil pan just to get the engine to live. When it threw a rod I changed to a small block. I am just about 100% over the novelty of this archaic engine. Sure it was a breath of fresh air in the 1960s when compared to the siamese intake ports of GM and Ford 6s. The slant worked well for a long time, but I'm done with over paying for the performance it returns. I'm so over it I bought a 1994 Corvette.

2 years ago i went to my machinist and asked if could rebuild a /6 for me. he could just never rebuilt one. he said no one rebuilt them.\they were so plentyful. you went to a wrecking yard and yanked one.
these motors were definitley taken for granted.
 
Briggs n Stratton will run forever too, so will my 51 ford flathead tractor.

They're outdated for performance.

You can get them to run quick, for what they are... but they'll always be what they are AND were designed as...economy car motors. Turbo them, they'll eat rod bearings sooner than later, nitrous...bent rods....high rpm oil pump gear goes out.... nylon distributor drive gear.

Love'em... but they stay behind to keep the fire going while the big boys go hunting for blue ovals and bowties
 
What do You estimate the market size is for guys & gals still building/turboing/N2Oing Hondas/V-tecs.......??? Miatas....???? RRR said it, cheapskates have owned the Slanty market, Miata Guys/Gals will drop $2400 on a Quaife & R&P set-up w/o batting an eye to go faster, can We sell a Slanty head for that much that would double the stk. output just bolting it on??? All of those shortcomings You've listed are the same for every hi-output little engine, there is always more heat/pressure/stress to get the job done, and it takes $$$$ to address them.

Disagree.
Have had a turbo 170 slant since 1979, never ate a rod bearing. street/strip car 10-12 lbs boost
Sprayed a 170 a 225 HP and never hurt a rod. Pistons, yes
170 slant at 7,000 rpm never lost a oil pump or gear.
Nothing wrong with the nylon dist gear, very little load on it.
Most problems I have had is head gaskets, pistons/rings. Cause: detonation from a bad tuneup.
Your results may vary

I was speaking for the 225, not the shorter stroke 'why bother' 170. Man.. even with a turbo them sons a bitches are SOFT...
See ... the 225 slant 'in stock form' is perfect...with thee exception of the exhaust manifold and induction....great motor... and the aluminum 225 was a great idea, I have one, but the open deck sucks and the liners separate at the tops from the die cast sleeves that capture them .....and then they leak at the head gasket cause of it.


Imho... if you really wanna help the slant, offer a new AL block that has a deck and then a cnc program for the existing head along with valves that gives 200 cfm by .500 lift...Last would be a solid roller...

But "by all that spent" you could have gone hot small block. And that comes from someone who LOVES me some slants.

Go look at .org
Numerous examples of turbo motors with out ‘bearing’ issues
Nitrous motors with out ‘bent’ rods
Rpm motors with out oil pump drive issues,,,
Drag cars that would blow your crap off the road,,

Who was the member here who had a record setting slant? MadMax wasn't it? His stuff was brutal. Mark I think is his name?

Met mark. His **** blew up. Great guy and built a bad *** slant... but that's like me with a 426 aspiring to top fuel hp... lmfao.

"Keep dreaming nerds" is my 1st thought, but I was there once. No worries
Fwiw I get 195-205cfm int/145 exh cfm out of a slant head with 1.70/1.44 valves. I'm not trying for it all...but that's a decent amount of work.
Now put it perspective..That's like a ported 1.78/1.50 318 head ... now take 2 cylinders away...make the others tiny and choke it indiction/exh...wahala the 170 slant.

Sorry but none of your nerd machines could blow anything "off the road" other than tumble weeds after I go flying past you and the draft alone throws your pos soap box racer into a fkn ditch.
My gawd, is this funny.
You really saying silly **** like that now? Lmao
 
Its really about usable range, if it takes wot all the time ...well...that isnt worth diddly onthe street

Need a considerable amount if cid to be in the zen range..:D
 
Anything will break if pushed to its limit.
