Hi, I bought a '66 convertible last year, and had to rebuild the engine. So I got me a workshopmanual for the '66. But when I pulled the engine, I noticed it was a 302 from '70.
Last weekend I got the engine running (still stalls in idle), and I want to ajdust the timing with a stroboscope, and adjust the dwell also if necessary.
First question : Do I adjust dwell and then timing, or first timing and then dwell ?
Second question : Are the specifications I found in the shopmanual the same for a 302 engine ?
Third question : I read you have to adjust the timing on different rpm's, but how is that possible without changing the settings at idle ?

Yes, time it at 8 degrees BTDC. Be sure you plug off the vacuum advance line first. No, you time it at idle. Set the dwell after you time it.

 

I don't know about dwell but as for the different timing, that's the total timing they're talking about. With the rpms up 3000-4000 with full advance you want a total of about 32* on normal compression. Now someone with more knowledge on stock can correct me but I run a higher advance 36* with better gas (96) and higher compretion...And of course this all changes if your running a supercharger...

 

He's talking stock Nelson.

 

Sorry to contradict Soaring but, you set the points (dwell) first and then the timing, If you do it the other way around, the timing will usually change a bit.

 

I have always set the points befrore and after I set the timing, but if I am in a hurry, I set the points after I set the timing. The timing changes the points setting, so it just makes sense to set the points after the timing. I no longer have to fool with that though. I have the pertronix.
Does anybody want to buy a real cheap dwell gauge?

 

Again, sorry to contradict, but timing doesnot change the points settingor dwell angle on any vehicle. However, pointssettings do change the timing.That's why you set the points first.n/m

We need one with a guy eating popcorn....

 

i would have to recommend you picking up a petronix unit asap as everyone on here that owns one says they kick ****

 

Yeah, get the pertronics setup and end this debate on points or timing first!!
