LIFT and DURATION (I & E) needed for the 306344 factory camshaft

[Deleted User]

I have a camshaft that I want to have reground to match the 306344 Hudson factory camshaft.

I believe the lift (s) might be ~ 0.356", maybe for both I & E, NOT SURE

Have no clue on the duration (s)

This would be for a 1954 Hudson Hornet twin-H (308)

Here's thanking you, in advance for clearing up this issue.

Why would you want to use an early step-down 232 & 262 camshaft in a 308. You're going to make the old girl breath too hard to get even the easiest cruise down the road. I'd keep it at least same as a '53 308 if it were me. However, it's your car - do as you wish !

Hello Jerry; according to Wait (another thread), there is a conflict:

apparently this is the scoop on this cam; quoting Ivanz62:

My measurements (Ivanz62):

306344 => 0. 354" lift 240 degrees duration

Apparently the 306344 cam is the standard, low hp cam for 53 Hornet ?

copied over from another thread:

HUDSON CAM HISTORY:

All Hudson engines come with the 306344 cam which became the standard low HP cam for Hudson in 1953.

The 1954 Hudsons were delivered with the 309742 (7X) Flat Top cam and later in 1954 was replaced with the 306344A series cam.

The 311040 cam (Super 7X high lift cam (.390 gross lift) came out in the fall of 1953 for all our Oval track racing and was listed as the severe use cam.

The HP rating of the 308 standard engines equipped with twin H power and the 7.5 to 1 CR head using a 306344 cam is 155HP.

When using the 309742 7x flat top cam the HP is 170 and when using the 311040 Super 7X cam the rating is 180HP.

A lot of bad info on this topic of cams. All the stepdowns had pretty much the same cam
From 1948 to 1954 with the exception of the racing cams that were dealer or owner installed. 344A in 1954 is very little changed from 344 in all earlier Hornet engines. The 742 and 040 cams were for racing with the 040 replacing the "chain stretcher" 742 as the choice in late 1953 or 1954. In 1956 the 308 came with hydraulic lifters and a somewhat higher performance cam--this gave 170 BHP with Twin H and aluminum 7.5:1 compression head. Aftermarket cam grinders made a solid lifter equivalent of this 1956 hydraulic grind. Buying one of those from someone like Randy Maas would be a step up. Otherwise, use what you have if it is not junk.
