I am looking for some opinions for timing specs/curve for my current combo.
What should initial and total be?
I realize this is relative; but in speaking with someone very knowledgeable they stated that less total is actually preferred due to better efficiency and better peak rpm. (34* vs 36*total) especially for 406 due to piston speed etc...
Current combo is 406, 72cc sportmans, XS274 237/[email protected]
108lsa-Manual trans, 3.73s
Current timing is 16 at idle with 4* in vac advance can( so really 12* initial)
total of 36* all in by 3k.
I am going to be having it recurved or just and more vac assisted timing for more initial or timing at idle and cruise would exceed 40* which should help mileage: shooting for more like 16-18* initial (so 22* or so at idle) with probably 6-10* in the can and total between 34-36*
I am looking to help cruise economy and fine tune things.
I am going to keep the vac advance which is connected to manifold vac (I know this is somewhat of a debate).
Does this seem logical?
additional input please
