I am new to hodrodders.com and this is my first post. I am having a problem finding the stock ignition timing for a1988 5.0L HO. I just aquired this engine. It was set up with NOS and unless I am mistaken the timing should be a bit retarded. I do not wish to run any NOS and am in need of the factory set timing. Any help would be greatly appreciated. Thanks.

From the factory, the timing read anywhere from 6* (too little) to 10* (ok, but it could still use more). I find that they tend to run best between 12*-14*, depending on what grade of gas you use. BTW............

Welcome to Hotrodders!

That much timing initial? Really? Most unmodified motors find their sweet-spot around 8 degrees initial, I find it hard to believe a stock motor running a roller cam and hardly any compression or duration would want 14 degrees! What about the total timing?

Your timing SHOULD be retarded, but only about 2 degrees per hundred horse, so it should be close (As that motor wouldn't handle much more than a 100 shot if that).

If you're having a problem with the performance, a former nitrous motor's smallest problem may be its initial timing....

Aaaa... wait a minute... WRONG SECTION!

Base timiing (stock) on all EEC VI 5.0 is 10 deg.

10* is correct.

Be sure you disconnect the SPOUT connector before you set the base timing. Then be sure to reconnect it when you're done.
