I wonder what's with the 1050 having the highest manifold Vac, implies it's the most restrictive.

Everything has a tolerance.

I'd be focusing on intake opening and closing points, not the resultant LSA that's still dependant on your chosen exhaust events.

The question is, do you think a narrower LSA would help pull the intake charge in on a long runner? Earlier intake opening, (If that isn't already optimised) more open area at TDC from the LSA tightening ? Get the column of air going stronger earlier. But you'd still need the closing point to get t...

Dominator throttle bores are spaced further apart creating less turbulence between throttle bores? Raised height from plenum shallow side. A further question. How would this set up perform if there was a larger csa dual plane? Dominator throttle bores bigger, lower airspeed turn into fall out vulne...

Big numbers from a stock unported airgap intake... if the 4150 supported all the airflow the engine needed with that intake then it must have been a jigher quality of a...

Sounds feasible, that's a lot of space up to the pushrod holes.

Looking back, I didn't think that progression system had any ignition amplification.

Did you check how big a gap it would jump ?

30 degrees isn't enough for a clean idle. It'll cook the pipes when you cruise. It's your multi use that needs a timing curve, not the power output since it will rarely be putting out max power. An advance curve also means you can run a cold enough Spark Plug that they won't become glow plugs when y...

Bigger Lighter Heads if you're corner carving.

Wouldn't be running locked Distributor with all the different intended uses.

Intake, meh, Carb will probably be simpler in the long run.

About a thou and a half stretch seated, every time it's opened it'll lose that, don't know how many times it can take that cycle.

Sometimes I would draw a white line on the rotor and drill a hole between coil post and number one then point the timing light down there, that was for reluctor triggers when you never really know, some would turn out to have the reluctor leads crossed.

Agree Tom but the rotor never changes relative to cap post. Timing is changed digitally. I just have to re-check set up procedure. You see, the rotor is only correct for the advance that you set it at, when the timing changes from there the rotor is still mechanically at the original set point. i.e...

Not hi tech but they work without issue!

Hasn't run the 6 yet.
