its a great design, the issue is finding parts at anything close to reasonable prices

[Maniacmechanic1]

Off topic but a Surprising amount of French Exotic Super High End Road Performance Classic Speedsters came with Vertex OAC Magnetos.
Past researches and discovery.

 

[Arjen]

The French Developed a Bullet Proof 4-speed close ratio fully synchronized transmission.
It was around 1956-1958 I recall.
For use behind the Chrysler Hemi engines in France.
I do believe Chrysler adopted the design refined and it became the A-883 4-speed used the entire Muslecar era by Mopar.
Hemi 426 & 440-six pack cars had the Close ratio & Low helical cut gearsets A-883 Hemi 4-speed.

The French & Italians had a huge role in 4-speed manual transmission developments & hypoid rear differentials & Posi traction we now take for granted.

The TH400 was all American.
Used in Italian Ferrari's & British Cars.
Funny.

I remember reading Mickey Thompsons personal Biography book Challanger there was not a single good transmission for racing in the early years for GM During 1950s...
But The GM Hydrostick.
Auto trans was Taboo yet.

The Cadillac LaSalle Transmission was used. 1939-1940.
4 of them used in Thompson 4 Pontiac V8 Engine streamliner.
How he got the linkages worked out ?
4 clutches...4 Cadillac LaSalle 3-speeds to shift exact same time on each gear change.

 

[Arjen]

This car has the French gearbox in it!

 

[Arjen]

Ok. We are at the point of measuring the timimg of the camshaft.
How does it works with the hydraulic tappets ?

 

[Arjen]

Just to make sure what we read is correct...
We are under the impression that the cam is one tooth out....

 

[Grumpy]

drop a penny on top of the lifter, to negate the hydraulic lifter seat,
and use a dial indicator and stand and a degree wheel

[Arjen]

Oh we make the degree wheels ourselves....
( how thick is a penny? ) this Europe....( We have €€€'s)

[Grumpy]

thickness is of no consequence, its just a common circular disk that fits in the blocks lifter bore,
rides over the lifter and won,t compress as would a hydraulic lifter seat,most chrysler lifters are about .904 diam. pennys are about .75, but larger than the inner lift seat diam.
your not concerned with anything but measuring the lifter movement in relation to crank/cam shaft rotation.

That is a Great Tip Grumpy !
I will remember the Penny Trick !
