FSD, that is a beautiful reply lol. I think you nailed it, I was thinking an accumilation of everything when it really comes down to valve timing. everythign else can improve it but the valve timing still dictates torque in the end.
this is much more of a cam topic as it seems it's the heart of what I'm looking for/try'n to understand
area's to think about:
Overlap - more over lap less bottom end, less overlap more bottom end
Lobe Centers - tighter gives more overlap, wider gives less overlap
duration - more is more overlap, less is less overlap
Lift- increases power without moving the power on the power band
these came from various websites, all conferming eachother.
so I'm guestimating for torque we can bleed little off to gain more. from what I have seen I improved toque alot from going stock to not...
so from the following I get
256/256 .233 114 has 28* overlap, with 1.5 rockers .350 lift, makes 68hp 117tq (140tq @ <1100rpm) (stock engine)
260/260 .300 112 has 36* overlap, with 1.6 rockers .480 lift
264/264 .300 112 has 40* overlap, with 1.6 rockers .480 lift
264/274 .300 110 has 49* overlap, with 1.5 rockers .450 lift, makes 135hp 167tq (95hp 168tq with same stock engine carb)
just guestimating the middle 2 could make more or less torque? I would guess more, but at the cost of HP.
I guess that's why the CAM is reffered to the heart of the engine.
