Advance the distributor until the engine pings then back off to the point the engine stops pinging, tighten the distributor. This will require driving a few test runs.
how do i find the timing on my 383 400 hp stroker motor
To determine the proper function of the vacuum advance on a 22R motor, you can use a timing light to check the ignition timing at idle and then rev the engine to observe if the timing advances as expected. Disconnect the vacuum advance line and check for a change in timing; it should revert to a base timing setting. Additionally, you can apply vacuum to the advance unit using a hand-held vacuum pump to see if the diaphragm moves and the timing advances accordingly. If the timing does not change or the diaphragm is unresponsive, the vacuum advance may be faulty.
It depends on which heads whomever built the stroker motor decided to use.
375 hp
Neither. The timing should be set to factory specifications.
That would be a destroked motor, and would result in a 285.
the crank shaft has been changed to alter the travel of the piston in the cylinder
If you wanted to put a 3.75" stroker crankshaft with a with a 0.05" offset grind into a Ford engine with a 4" bore (such as a Windsor 351) you could make a 383ci Ford stroker. But as for making the traditional Chevy stroker engine, you can't turn a Ford engine into a Chevy engine.
The very basic answer is the crank shaft. There is a greater distance from the main journal and the rod journal on a stroker. This causes the stroke of the piston to be greater from top to bottom in the cylinder. Thus the term stroker motor.
The 2UZ-FE motor does not have a timing chain but a timing belt and it should be changed between 90k and 100k miles along with the water pump.
6, to 8 degrees, advanced. Advance it as far as you can, until the motor pings on acceleration, or, under load.
There is no timing ajustment, Its controled by ECM- Computer.
