You think if we round up some demand for some intakes & heads it may

make him give in?

Lets face it if enough guys are willing to commit to an intake and head if

it helps matters.

I for one would like to have one intake and cylinder head providing they are

resonable cost wise. There has to be way more guys out there that would

also be willing to commit up front if it helps.

ok, last night i heard of a guy in here in melbourne that is making his own quick change axles. i've asked my source to do a little more sniffing about what he actually does, this could be our low volume, non ferrous casting solution to get the intakes and heads cast, if the patterns ever see the light of day

[Deleted User]

From what I can tell, the intake looks like an Edmunds knock off. Nothing all that special there.



What would sell, would be a Twin-H copy with provision for something besides a single barrel. Perhaps dual 2 barrels or a small pattern similiar to the Clifford 4 barrel manifold. Flexibility with a dang well proven runner design. I'd be in line for that in a heartbeat.



The Gibson-Binks head, that is unique and evidently effective if they sealed 12 psi of boost under it.



Next month the 7x exhaust adapters are scheduled to be poured. I'm anxious to see how that will go.

Hi,

Just wondering if anyone is modifing any Hornet Motors this winter?

[Deleted User]

Yep--may put a belt drive on my '41 this winter and a Ron's fuel injection



Randy

Ol racer

Randy,

That sounds real 'Trick' and may really enhance the Torque output... I been researching TBI set-ups for the same reason.... Good Luck

Interesting stuff.



I would have thought Randy to be more interested in a Weber compatible throttle body system. I'll save the Ron's link, you never know?



http://www.twminduction.com/ThrottleBody/ThrottleBody2900-FR.html



Since my Hudson project has bogged down due to economics, I'm allowing myself to dream. This type of individual runner system under forced induction and electronicly managed would be my ultimate dream.



Dany Spring gave a link to TVM wayyyy back when I was only discussing on Inliners.com (several years ago now) - I've kept up with TVM since. Who knows, one of these days?

mark, the photo from TWM that got my mind on the run was the one of the throttle bodies with the bosh K-Jetronic injectors plugged in. one of the classes im interested in running at the strip (a long time from now- like you finances are limited) forbids electronic injection. what they have effectively done is turn it onto a cheap version of a hilborn, with the air flow "paddle" out of the system it has no load metering capability. what they have done is confusing the heck out of me and i like it!

[Deleted User]

i just found this photo on another board,this is a cnc machined two piece head for 337 lincolns. the interesting thing here is the undercutting of the valve relief. as i understand it, there is some hand finishing to be done yet. i wonder if it really helps the airflow around the valve, or if its just creating a dead spot and losing compression. my airflow theory is dusty dusty dusty (i havent used it much since i was a motocross mad teenager) but slowing the airflow should pick up some mid range torque. Mark this could be of benefit (move the power back down the range) on those longer intakes we discussed. hard to say until you have a go at it!

[Deleted User]

Mike Davidson, in his flathead book series "Flathead Fever", measured a flow loss with the "eyebrow" head relief just as you have pictured.



To my knowledge, nobody has flow tested a flathead with the time and effort Mike has. He even casted a transparent resin head, with appropriate chamber profile, to test flow patterns etc.



However, I've also talked with Randy about this and he says relieving behind the valve turns the Hudson loose. I'm not sure if it was a typical "eyebrow" relief or not. I kinda believe it was an "unshrouding" relief and not the two-cut type as is in your picture. Randy is much more qualified to speak for himself - obviously (I hope he chimes in).



Mike Davidson is an Aussie. You may well be able to speak to him directly. He and I carried on a good e-mail conversation a few years ago now on these topics. He is a fan of the Hudson, but dedicated to the smaller flathead Fords. He has never flow tested a Hudson and said that what works on a Ford, may not be the ticket for the Hudson. Only some Hudson specific research would prove what worked and what wouldn't.



To my knowledge, nobody has flow tested a Hudson engine. If they have, they've sure kept it a secret.

bit of a bump up the list since randy still hasnt seen this.

maybe the eyebrow relief, if done in moderation (enough to keep a good radius) would improve flow around the valve. there is always the trade off of lost compression though

[Deleted User]

When relieving around the side and back of the valve (manifold side) make a perfect round straight cut. Forget the radius on the bottom. I use a seat cutter on a winona head shop to do this. Works for me-may not work for you (disclaimer). Loss of compression is less than 1/2 cc. Milling the head .003 would make up the difference. Passing on my secrets--no charge.

FYI

This may be an appropiate Thread to attached a few pictures of a project that I have been working on (& off) several yrs building a highly modified Hornet Motor similar to one that I stock car raced all during the '60's in this Tri State Area, but updated with some modern technology, then installing into a lightened Stepdown painted identical to one I drove (and raced in high school) to occassionally drag race. I set aside this winter to finish this project and begining to see closure....however It is not a show Car.



I was pleased to learn that after decades away from from building my last modified Hornet Motor that others had and still were racing Hornets and modern updates were now available. The distributor conversion was from Ron Fellows (clutch man) working on Fred Hawthorn's dragster. The oiling, head, and cooling Mods, (posted on this Thread) by Rudy Bennett, were helpful as were the availability of modern racing Parts (and advice) from Randy Maas .....



Briefly the Block is bored, stroked, Decked, balanced, large valves, wide deep Relief, Triple 2GC Carb setup, NOS, Clifford Headers, ARP Fastners, modified Clifford aluminum head, Isky 446 Cam, Maas dbl roller Chain, HEI Ign, MSD 7AL Electronic Box, Custom Damper, lightened flywheel, B&M Race converter, Maas Adapter, Modified 'race only' Turbo Trans, Ratchet Shifter, Shiftnoid (TBD), narrowed 9'Ford Rear with Spool & 31 spline axles, Individual plumbed Air Shocks, Traction Bars, Mag wheels, M&H Slicks, Goodyear 4" front Drag tires on vintage Fenton mags.



Additionally, the Chassis is severly gutted to lighten with polycarbonate windows,(except windshield), aluminum seat, sub-frame connectors, moly roll cage. Line Loc, small fuel Cell, rear Battery, Kill Sw, GM driveshaft, Safety Strap, etc.



My ET/Speed expectations are not set real high considering the car is probably still little heavy....I keep two pictures of recent Drag Hudson's that help inspire me to remain focused on the Project, Gary Ellard, who raced his '53 Hornet over 40 yrs setting Records in both stock & modified Classes and Randy Maas '41 Cpe that continues to lower ET's with his 21st Century developments....

Chuck,Very,Very,Very Fine looking Hudson you have there and I know that Its Going to RUN ,and Fast.

Please email me some Pictures so the Locals and My son Randy who Runs out of ATL-Drag way can see what they may only see the back bumper at the Strip. Hudsonly Rudy and local Hud-Nuts

Mark- It's been a few years, but there was a guy that ran a Hudson at Bonneville, I want to say in the early 1990's. IIRC the car was a 52/53 4-door Wasp, painted bright pink with a highly modified 308. He had several articles in the WTN and at least one of them showed photos of a sectioned scrap Hudson engine that he was using for flow bench tests.



He ran the car at Bonneville for several years in a row; he sold T-shirts in WTN to help support his effort. I had several of them; if I can find one it may provide his name and at least the car number. I'll also look through my old WTN's and see if I can find any of the articles.

You need a newbie pit crew member when ypu have that ready for the strip give a holler. Give a holler if you even need help wrench turning.

Anxious to see the car at the nationals. Keep your expectations high. Keeps you thinking and experimenting. Did I notice the motor will be snifing the nos? Everything looks great--Good job.

The car you are thinking of was run out of Astoria OR. Hot pink with dark red flames, right? I forget the guys' names who were running it(maybe Steve Kahn?). One of them visits a hot rod shop my buddy lurks around occasionally in Vancouver WA. Through him I have learned that the car itself is too far gone (due to the salt) to ever be driven again, let alone go back racing. The powerplant is probably still there somewhere though. I'll see if I can find anything out...

Ol racer

Randy,



Good observation; If the Head gasket holds I will try a little NOS as an enhancement to race Fuel. (Just a little because of only 4 Mains)



Thanks for all your assistance,



Chuck

Hey Olracer, is that a fiberglass front end? I thought I was the only one with one of those stashed away.:D By the way, I need the grill to complete mine.

Looks like a sweet car ol racer!! Any chance of a couple more pics of the intake to ponder on?



Keep it up

Here is another view of Tri Power with progressive linkage. Because the Pontiac Carbs were wider than the tubing I milled the bases off & turned the carbs sideways for better flow to each port.

Sure is Nice Chuck and i know it will run. Do you have a picture of the GM dist ? Hudsonly Rudy

Rudy,

Here is a picture of the Chevy HEI. I found drilling the adaptor to pin the shaft at 180 degrees apart worked the best to elimimate any wobble.
