Same specs as the TW400-6 with a 575  lift to suit stock heads.
 :agree: someone needs to try it out

I run the 408g and have run the 400g with HTCC heads and some added compression. Do you think there will be a big difference for a stock 103 in the 777 over the 555? With some lift and a little more duration, maybe up top. But 1 degree on the intake is in the wrong direction for stock, IMO.
Anyone else think this is going to take a little work to get a gain out of it? Meaning, it might bolt in, but to shine I think its going to need some extra.
Where do the stock head fall flat in lift?

The 5 still looks like the best candidate for a bolt in to me. This will work if ya got the CCP at 185, but he list it as a bolt in, not IMO  :scratch:

I always thought that the 408 bolt in should have had about .575-.590 lift.
.510 with that timing is limiting. I love my original 408 with .650 lift but its anything but bolt in.

TW5-6 or TW7H at most with stock compression.(9.2:1 on a 96, or 9.6:1 on the 103 which is the future it looks like)
Like that early intake close.
Now if I could bump the compression to 10.5:1 with just a head gasket I could see the new 777 being a sweet ride. Otherwise 10:1 with the 555 couild be the ticket for the all day rider.

If I recall correctly when I spoke to Bob W a while back. He indicated the 5-6 and the 7H would need different springs in his eyes. I know some were running them with the stock springs but    :smilep:  Will the 777 be a "true bolt-in" in stock heads?

i personally wouldnt install a .575 lift cam with stock springs,coil bind may be OK,but the seat pressure would be suspect

Looks a lot like a woods 8 advanced 3 degrees.... or mighty close to it.... The woods 6 and 8 cams are real solid performers so this should be some middle ground solid performance.  JMHO

FWIW I like my 555s that are set up at 10.5:1. As hard as I've tried I can't get any audible ping even in 110 degree heat.

Looks good. The added lift would work good with head work.
I think the 555 works well with stock flow heads. Im not a profesional but Im going to have to say you wont see much gain going from a 555 to a 777. Unless you have ported heads. you may however see a a bump in the top end, slightly.
I would love to see a cam:
22/43
45/20
245/245 Dur
.580/.580
Just to change things up, and it wont look like its just an improvement on a cam he already has.
I would love to have a set of the 777 for a 107 kit and headwork, but Im still having a hard time to save up for just some head work :emoGroan:

 :emoGroan:

Why is that many think you need ported heads for bigger cams?? While it's nice to utilize the higher lift to increases then flow to the motor. Increasing the duration and lift do the same thing as porting. They increase the flow.. On HDs it all about matching flow to the motor.  If one were to set up a motor to run the 555 (say a 103) and installed a 777, it'd probably loose low end to get some up top. What would be nicer would be to bump the compression, use a little less flow heads (but still more under the flow/lift curve).  In your case, if running a 107 kit without ported heads I'd bet that if you replaced the springs on stock heads to handle the increased lift and  bumped the CR to keep the same CCP as the 555s that you make more power throughout the power band.

If I were going through the routine/cost of removing the heads to increase compression and replace springs, I"d port the heads.

I'm surprised to read this from you Max. I thought you knew better.
 So if I'm reading this right you're saying don't bother porting your heads it's a waste of money just put the biggest cam you want in there & let it rip. :wtf:
Good luck with that.
And going to a higher lift cam with the same duration doesn't give up any bottom end & The ONLY way you'll gain anything on top is with ported heads.

I do I just worded it wrong.. You can use longer duration to pick up the slack in poor flowing heads and a bump in compression will help too.. Are ported heads not worth the money? No, they are worth doing. (I think I go may negatives right  :wink:)  If you want cheap HP use a longer cam and higher CR. Its the idea behind the "cheep thrills" build.

It's more along the flip side.. Lesser cams can take advantage of better flowing heads in some cases even better than longer cams so saying bigger cams need ported heads is not correct.. Smaller cams can use em also..

"The ONLY way you'll gain anything on top is with ported heads" I gained more on top just putting a pipe on my bike, the cams gave me a little more too, the heads did make a difference but they weren't the only way...

You gained more with a pipe than the heads?
Whose heads?, which pipe? Before and after testing rquired, for each.
More on top, hmm, where I live hard to ride there, all the time.

Hey Larry, better quit doing heads and go to makin pipes.  :hyst:
