VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1912-1928 4 Cyl Valve Springs

Hi,
Does anyone have the following information on the valve springs for 4 cyl Chevs form say 1926-28:

Spring outside dia.
Spring free length
Spring height valve closed and open
Spring tension with valve closed and open

Any information greatly appreciated.

Do you have Verlan Husman's phone number or email address? I have noticed that at a tour this year (maybe the National 4 cylinder Tour) Verlan was carrying around a head and valve train he has put together with some modern parts. I don't know if he is a member of this site or not. He is also the guy that has modified a modern throwout bearing to fit the four cylinders. He is listed in the 2006 Membership Roster as being in Brooklyn Park, Minnesota. He probably has a handle on the specs. you want.

Hi there
I hope this will help you out;

Motor valves for 1927 & earlier single exhaust port head 1-1/2" diameter
late 1927 & 1928 Chevrolet 2 exhaust port head 1-21/32" diameter
Valve lift intake & exhaust .300" 19/64"
Weight of finished valve 3.2oz max
Valve stem diameter 5/16" .310 - 311"
Spring pressure valve open 65 lbs approx
Spring pressure valve closed 39 to 43lbs
Valve lash .013

Hi Mr Mack & Don,
Thanks for your information and help,much appreciated.
Mr MAck,Verlyn was just out here for our latest Chev 4 Tour,and he showed us the 4 cyl clutch throwout bearing conversion.It was an interesting bit of work,and he had lots of very interested 4
bager owners looking over his handywork.

Don,thanks for the tech info you provided on the valves & springs.I would still like to know the free length(unassembled to to head & valve)of the spring.I have the chance to get some made,and this is why I'm trying to get as much information as possible.

Hi

I don't have one handy right now but I know you can buy them from Kanter Auto products in Boonton New Jersey 07005 - www.kanter.com. They use to be around $60.00 US per set. Egge obsolete auto parts 11707 Siauson Ave Sante Fe Springs CA 90670 or The Filling Station 990 South Second St Lebanon OR 97355 www.fillingstation.com I would try The filling Station first I deal with them mostly and have nothing but good luck with them. They will probably give you this info over the phone. I have their catalogue here but it doesn't list the springs but I think they do have them or could advise you.

Good luck
