What should the timing be on a 383 stroker engine?

What should the timing be on a 383 stroker engine?

Okay chevy 383 stroker timing should be 34 to 36 degrees of total timing. Bring the rpm up to 3500 to set total timing. You should have a pretty steady timing mark at that rpm, if you have an unsteady timing mark you need to look for other problems. Such as distributor problems or distributor gear movement.

What should the timing be on a Chevy 383 Stroker?

Bring the engine RPM up to 2500-3000 RPM. Assuming that the centrifugal advance weights and springs have reached the maximum mechanical advance at the above RPM range (this can be adjusted by lighter or heavier combination of springs), set the timing at 32-38 degrees. Do not exceed 40 degrees.

What is the ignition timing on a stroker engine?

Mechanical timing is finding absolute TDC where the piston is at the top of the compression stroke. That is fine as a starting point. Ignition on the other hand must fire before the piston reaches top dead center. A stroker engine was made using parts from 2 different engines so ignition timing because of higher compression ratio can be tricky.

What should the BTDC be on a Chevy 383 Stroker?

Your 28 degrees BTDC at 1000 RPM more than likely has got the initial and some mechanical advance together because of the RPM. With the engine fully warmed up and the choke fully open, dis-connect and plug the vacuum advance hose from the distributor. Bring the engine RPM up to 2500-3000 RPM.

When does power drop off on a 383 Stroker?

Start retarding the curve till you feel power drops off, (Do this with the rpms near where the curver is all in and above) it will drop off withing a couple degrees….advance it back up about 2 deg above this piont…any further makes the car sound stronger, but the power drops off very slowly as you get higher.

How to set ignition timing on a 383 Stroker?

JMO if your not sure about your pointers. get you a screw in piston stop and turn you engine over by hand and then you can get perfect top dead center and set your pointers then. they cost only around $12.00 for the comp ones. Good luck Andy if not using a fixed distributor, need to take the engine to 3500 rpm to set total ignition timing.

What’s the total timing on a Camaro 383?

I would disconnect and plug the vacuum advance. Set the timing @ 36* BTDC at 3,000 RPM (or the point at which it no longer advances). This is your “total timing” Let the engine come back down to idle, and note where the timing is at idle. This is now your base point for tuning.

Is it correct for Chevy performance sp383 Stroker?

From the posts and articles I’ve read, a lot of other sbc 383 (mostly street driven) seem to have positive results with a similar timing and advance curve set-ups when using a longer duration camshaft. As far as “… it is correct for this engine as chevy performance requires?”

What should the compression be on a 383 Stroker?

I’ve built several sbc 383 or bigger and depending on heads cam and compression 34-38 degrees is the norm.My current 388 likes 38 total. Visit spib’s homepage! Visit cncmotorsports’s homepage!
