Thats where its idling happy.
Mind you, i have yet to drive it.

But, Ive heard everything from everyone....
"Start at 6*." :haha: (wouldnt even feign the notion of starting at 6*.)
"10 is what you want."
"No, 12."
"No, 16."
"But, mine takes 20."
And so on...

So, I started at 12.
She liked 14.
16 sounded better.
18*, you can actually feel the idle in yer chest...

At 20* it was either ping'ing, or the valves being out of adjustment made it unhappy.
So I backed down to 18*, adjusted the valves (engine off), and the starter gave out. :haha:

What should I be doing, that I dont know about?

You should run it at what its happy with. My 355 in the short bed is initial of like 18ish for a while. It had too much total though and would ping up top under load. I backed the initial off to 16 instead of taking advance out of it just because I was lazy. My old monte SS had a 305 that loved 14* initial timing on regular gas to boot.

Is this driving yet? Cause all this timing talk doesn't mean anything without a load :dunno:

That's what I was thinking too.

It was nice living in the country, I could go to a long strait road for test an tune sessions with little to no interference.
 
my .02..

I think you are throwing WAY too much timing at basically a very mild motor, and it's gonna ping like an epileptic graffiti artist under load.....

there's no reason it should "want" that much timing with your specs.. whole different ballgame under no load just revving...

worry about brakes and actually driving it down the street before some mythical timing #... :deal:

figured as much . . . guess smart phones are NOT so smart . . :whistle:

years ago I had a sb350 and it had mix matched balancer and cover so timming marks didn't line up .

best way I found to time it was ROAD TEST . darned if I didn't have it on the 3-4 time out . she ran great for a long time till I found a nice built 400sb to replace it .

like said get her runnin and driving safe and road test it .

My 350 in my 82 was like this for 22 years and it still ran great when I sold it. I would advance it until it pinged, then backed it off a little at a time. Worked great and it always ran very clean.
 
Put the starter in.
In the rain.
Drop the truck, crank it... it failed to engage the flywheel.

I'll figure it out when it stops raining.
I'm pretty sure its just bad outta the box.
Bendix spring, or something.
 
it happens....... we have ton's of merc marine apps with gear reduction starters... never had an issue with em.. high comp/hp, it's all I'd run...

Alright.... i failed to give credit, where it was due. :haha:
That was one of the best automobile metaphors I've ever heard. :pimp:

I was too ashamed of being called out on timing to reply... :doah: :haha:
 
it's all good, we're just trying to help... you do fine man.. :waytogo:

sometimes the 1/2arse comedic approach helps a bit... ;)
 
good deal... :waytogo:

us too, gonna pour all weekend.. :(

think I'm gonna prep/clean the Lab tomorrow for Mutt's tubebed gig and start cutting up the mounts and feet....
 
Speaking of timing.... I was catching up on my reading yesterday and in a recent HOTROD magazine they dedicated the issue to 50th anniversary of the 426 Hemi.

Apparently, when it first came out a lot of the drag race guys hated it and couldn't get the power of the smaller 39x cu in they were already familiar with. Out of desperation, one guy decided to put a bunch of extra timing into the motor (actually hoping it would blow up so he didn't have to keep using it)... he went from 34* to 40*

The car picked up a bunch of HP and got a lot faster.

He added even MORE timing (50*)....and the motor didn't blow up there either... in fact, it picked up even MORE power and ran faster still....

Apparently, that secret didn't last long and all the 426HEMI guys pretty quickly realized that for whatever reason, that motor loves way more timing than the previous generation did.

Guess there really is some truth to the expression "Give the motor what it wants..." instead of just choosing a value that seems popular on the interwebs. :D

I always just get it running with the cap off and turn the idle way up so it pulls the level down then fill it.

I hadnt considered doing that.

we do it in older boats, obviously it's a raw water cooled system so they act a bit different, but when you have a carb, and tach for resetting idle in every dash, it's easy enough...

EFI, not so much unless you have 3 hands.... :haha:


git r dun Mike..... :waytogo:
