383 stroker

Hey guys I’m working with a 1970 chevelle with a 383 stroker crate engine. I really need help with setting the timing of this engine, I have a snap on dial type timing light. How do I set the initial timing and at what rpm do I set it and also the total curved timing. I was told that I can’t go over 33 degree total ting on this engine. My issue is that I seem to be all over the place. I need to know at what rpm I should be to adjust the initial and total. I’m new to this and would really appreciate the professionalism from you all. Thanks in advance

We all could ‘splain it but I’ll just post this link.

Where should I set the timing on my performance engine?

Hey thanks a lot for that write up.

Now I’m having an issue with it running really rich. What type of carb settings do I start with and how do I go about fine tuning. Currently running a 700 Brawler carb. I have the front screws backed out 1 1/2 turns from seated position and the rear screws the same, I was told that the rear only need to be backed out a half a turn as that’s not the primary side and it do t need to be the same as the fronts. Can someone please help me out. Thanks guys!

From the same source RWENUTS posted above, under "Tech tips"
How to adjust the mixture screws on your carb

4 corner idle carb, all mixture screws should be roughly equal, and within 1/8 turn of each other.
You'll probably end up somewhere near 5/8 to 1 full turn out.
The 1-1/2 turns out setting you see posted a lot is just to get a new or rebuilt carb up and running on the engine, so that you can then adjust it to fit with the engine.
It will almost always be way rich at that factory setting.
