Cam degree..

[RustyRatRod]

I wouldn't call it low compression it's probably about 9 and 1/2 or 9.3... 408 with forged dished Pistons.. going in my daily Power Wagon...
If you read through this straight up I had it at about 110.5 and then did four degrees advance and I'm at 106.5..
Again I'll talk to Ken in the morning and see where he wants it...

Ok and what heads?

 

[RustyRatRod]

It's a TRUCK. Leave it there. All it will do is give the bottom end torque a bump up. You don't need Ken for that. Also, once the timing chain breaks in and stretches a little, it'll probably be spot on where the cam card says.

 

[Bewy]

Agree with RRR. Heav-ier vehicle, plus compression not that high, all candidates for an advanced cam position.

Semi fresh 596's off the duster from when I switched to the speedmasters..
K-line guides, Crower springs, 2.02's... a little bit of port work...

I think you'll be fine. I'd leave that joker RIGHT where it is. What brand timing chain set did you use?

Well you're going to love this! Lol... First off I'll answer your question it was a summit billet 9-way... That seems to be a nice setup from all the others I've had..
Anyways first call goes into Ken.. he says put it at the 108.5 and run it.. gives all his reasoning back and forth and doesn't want me to run into detonation problems with cast iron heads and in the neighborhood of higher compression.. not real high as we know it but up there...
Then I called Ted the engine builder on an unrelated subject but still approach the subject with him... He says leave it right where it is at 106.5 and talks about change stretch under the load of all the valve springs and such...
Ken talks about adding a little more timing to gain power back instead of running into the possible issue of overtiming and having to take the timing cover back off again....
I would have loved to have had these two on the phone together and just been the fly on the wall...
Ken grinds cams for a living...
Ted builds engines for a living..

I'd go with the engine builder.......and I'm giving Ken all the respect he's due. He's a genius, but chain stretch is real and documented. If you put it in at 108.5, it ain't gonna stay there. And as someone else has already said, I'd MUCH rather see it a little advanced, than a little retarded. Just do whatever you feel comfortable with. It's really splittin hairs for what you're doing.

I'm probably just going to leave it so I can side with what I really want... To be lazy and not have to mess with it again! LOL..
My engine builder did call me back and he is close friends with Ken (Ford people....) and who turned me on to Ken in the first place but anyways he called me back and said he has my oil slinger for me actually a stack of them LOL... I'll run out there tomorrow and grab it so I can go ahead and button this damn motor up...

Install it @ 107.5

My set up only allows 2° at a time...
106.5 108.5 or 110.5 or further each way..

Now I can't remember the shafts I think it's driver side forward and down and passenger side to the rear of the engine and down for the notch for The rocker shaft?..

My vote would be for 106.5

Well you win the big price because I'm too lazy to change it now....

 

[4spdragtop]

Yes, down and to the left, BUT that depends on what style of notch. I just learned of different "notches" recently

Now I can't remember the shafts I think it's driver side forward and down and passenger side to the rear of the engine and down for the notch for The rocker shaft?..

I always liked Ken lol, now Ted will have you running race gas on the street if you listen to him. On the cam timing it is splitting hairs and I don't think you would be hurt either way, might just narrow the tune up window a fuzz in certain situations.

I'm going back to my resto thread...
The heads just keep coming today..
Besides Ted coming up with the oil slinger I spent the whole day going backwards......

 

[Krooser]

I'd echo RRR, I'd rather be advanced than retarded..

That's what they told me in school....both years.

 

[RustyRatRod]

Passenger side down and to the rear, driver's side down and to the front. BUT some are different, so here's how you be SURE. The small oiling holes point down and toward the valve springs. Simple.

 

[RustyRatRod]

Me too, but it still didn't help me.

 

[Bewy]

Harvey Crane....another cam grinder.....said: the cam needs to be advanced or retarded a minimum of 4*......for the butt meter to feel the difference.

I'm not a cat person but that cat seems to like me even more because of it.. I was just rubbing it's stomach yesterday and asking if it ate one of the neighbor kids basketballs...
