7" rods, 10:1 comp.- what timing numbers/curve???
Hi all,
i am hoping someone can give me advise as to what ignition timing numbers/curve i should have for the following combination:
7" rods with flat top 89mm pistons, 10:1 compression ratio, 290 degree cam, headers 4-2-1,twin dellorto dhla's. redline@ 6200-limiter set @6100-staying below the 3rd harmonic.
i need to buy some springs to fit my lucas lotus excell electronic distributor (no vacuum)
i think it will be something like 12-14 degrees initial with an all in @ 30 degrees. (correct me if this is a bad starting point) I am liooking for when "all in" rpm is and if i should have a 2-step timing ramp and what and when it should look like-rpm vs degrees at all points of interest.
thanks
