To answer your question;
In about 2000/2001 I installed a Milodon late-style Hi-Flow, (plated 8-vane impeller), HD (5/8ths shaft) pump, and Hi-flow (195) stat. on my 367. They are all still in operation. Doing the math, they have rolled on over 100,000 miles. So I have no problem recommending what I bought in that year, lol. I run old-style Prestone coolant at 50/50
--------------------------------------------------------------------
Additional info:
I run a 7-blade, all-steel fan from a 73 Dart-318 with A/C;
but the clutch is off an old Ford V-belt pick-up truck, maybe early 2000s,
My combo is very similar to yours, except;
no pusher fan, and under-driven pulleys, and my cam is just 230/237/110, and
I run the Commando box, with 3.55s, and a GVod.
--------------------------------------------------
Just FYI;
My ignition Timings are;
>Normal Idle-timing is 12>14, cuz too much more and the 750Dp gets a lil jumpy. But she idles real nice at 550@5*advance.
>My Power Timing is 28* at 2800, going to 34* at 3400rpm which allows me to run 87E10 full-time, without detonation, even up to 195psi, the highest I have tried.
>To get that timing range,
the Vcan was modified for 22 degrees, and I run a dash-mounted, dial-back, timing module that has a range of 15 degrees, which I set to +6*/-9*.
Thus; the total range is;
34d +22v + up to 6 on the module=62*;
and minimum is, 14 less 9module= 5*.
>Cruising around town;
32mph=2000 in Third; 2700 in Second, 4400 in first, and
yes it idles around at 32= 1400 in fourth. but I only do that when tip-toeing past a copcar.
> She runs 207*F at the stat house, no matter what she is asked to do, including;
parading at 500rpm@5* ignition advance =3.6mph, and/or
cruising the hiway at 65=2240 rpm, at usually 56* of timing. But could be more.
Oh and, the carb gets fresh ambient air from above the hood.
Your results may vary.
