Today I measured the camshaft with a degree wheel (only on cylinder 1 and intake valve). The centerline according to the camshaft spec should be 106*, mine is 106.5* after 4 measurements, so it is good. Lift 0.501, ignition timing is also 292 as spec. Does it make sense to move the camshaft 4...

Thank you, now I understand, that's what I meant, whether I won't worsen the parameters at low revs by delaying the intake valve. So for now I won't move it until I take accurate measurements.

Yes, exactly. Before the piston reaches TDC, the intake valve opens and the exhaust valve is almost closed. If I understand correctly (according to Tony's video), when the piston is at TDC, both valves should be in the same position. In my case, at TDC, the intake valve is very open compared to...

If I translated the video correctly, the valves should be in the same position at TDC. And the difference between them of 0.006" is 2 degrees.

Unfortunately I don't have a degree wheel, but I calculated that the piston in TDC coincides with "0" on the muffler, I pulled the pushrods and put a simple tool (flat bar) on the hydraulic pushrods, it turns out that the intake valve pushrod is 4-5 degrees higher than the exhaust pushrod. I...

One more question: is it necessary to fill the engine with rubbing oil with zinc (e.g. Driven DBR), or can I fill it with regular oil that contains zinc and phosphorus (e.g. Driven BR40, Millers Classic Pistoneeze)

This is probably the maximum gear ratio I could use without exceeding 2800 engine rpm at 60 mph on the highway.

Thank you for the info, great knowledge:thumbsup:

Thanks for the info, too bad there are no engine dynamometers in my area. It could be a lot of fun to test the engine before putting it in the car. Can any of you tell me from your own experience what I can expect from my 440 with the setup I have (assuming I have a 2800 converter and 3.55...

The engine has been started several times, after adjusting the carburetor to 1000 rpm it works satisfactorily. Will moving the camshaft by 4 degrees increase the power and torque in the lower engine speed ranges? My knowledge of the effect of camshaft adjustment on engine operation is still too...

Gaskets are standard modern ones, heads were ground, but I don't know when someone before me ground them. As for moving the camshaft by 2-4 degrees, "+" or "-", currently set to "0"

I think you're right about 10:1, and the camshaft is probably causing that compression.

Thanks for the info, the shaft is indeed sharp (that's what I had because it was supposed to be used for another project), if it doesn't work out, I'll consider replacing it.

Thank you very much for the information

Hello all mopar enthusiasts. I'm looking for help selecting differential and converter gear ratios for a 1969 440 magnum engine. I have a 1972 dodge charger topper x with a 383 magnum engine (old converter of unknown origin) and a 2.71 differential gear ratio. Currently rebuilt 1969 440 engine...

Does anyone know what car this Chrysler radio was installed in?
