Since 2004,
I've been running a Hughes hydraulic HE3038AL, which I have installed at 108, so it's
276/286/110+2/61 overlap(60Effective)/114 compression/105power. /lifts of .549/0.571 @1.6rockers/and .050s of 230/236;
Installed with Hughes anti-pump-ups, at what started out as .020 preload, but some of them are now, after 50,000 miles, ticking.
My Scr is 10.95, and cylinder pressure is about 177psi with OOTB aluminum Eddies.
It's a clutch-car, so it's sensitive to to pressure loss at low rpm.
That is to say I hate slipping out the clutch like a 302Mustang . It's a Mopar. It's supposed to be a dump it and go deal. Now, with a 3.09 low and 3.55s the starter gear is 10.97.Together with the heavy factory flywheel,this makes it so. Blip the throttle just a lil, slip it out hard and fast, letting the flywheel do the work, and drive away like it was an automatic.
I miss the top-end rush of the DC 292/292/108, (

I miss the stout off-idle torque of the 270/276/110 Hughes, (223/230@050), so
I put up with the 276/286/110,(230/
[email protected]) having made the changes to run it.
And I have become used to it.
I set the engine up to run the 292 cam with a thin gasket and adjusted the Scr on each of these cams, in various ways, that most guys would never take the time to do, to achieve about the same 180ish psi. So I believe I have a good idea of what to expect at that pressure, and I am unwilling to run any less. I can't go back.
But I would be excited to go forward with more pressure and more duration @.050. How is that possible? Without more machining ,and staying with a hydro, it's not.
But since this current combo has gone 93 in the Eighth, I just leave it. Certainly, as a streeter, that is fast enough.
