390 timing mark location

Hey folks,

I'm in a spot here and hope someone can help me out. How far away from the "0" mark on the pully is 10 deg BTDC. I can find the "0" but no other markings on my pully(internally dampened right?). Is it an inch or the length of a 1/4 dollar, nickle,,what ???? I need to set the base timing so I can adjust the carb and idle. Most seem happy with about 10deg btdc.

I was told by the PO I have a 1964 390 from a demo t-bird.


thanks

bob

Get an adjustable timing light and you can use 0░, TDC for all your timing. I have never seen or heard of an internally dampened FE. I have however, heard of a dirty damper so you can't see the marks. I don't think I ever saw a factory damper without at least 10░ marked and most have 30░ marked.

HMM , well perhaps I'm wrong. To me it just looks like 2 seperate pully wheels bolted together. I'm new to FE's.

So anyway. I think my mark is way off. It reads about 20deg to the passengers side or down side. When I get it closer to "0" CCW is retard and the closer I bring it to "0" the worse it gets. and Then I get the "hot start" issue and then it diesels. If I keep it about 20 adv?? it starts nice and no over-run. ???


The Vac adv is plugged. and I cannot find any vac leaks. At low Idle it's about 16Hg then 20Hg at about 1k rpm. The Edelbrock is set at 1.75 turns out. Engine was about 180+190 temp.

Any ideas?

So check the TDC. Pull #1 plug and get the piston as close to TDC as you can and check the mark.

update

I found the marks and yes I was reading it bass ackwards.

Still. It seems to like 22deg that seems high. If I try to bring it in I get clatter and hard starts. Can this be correct? Am I not using enough idle screw on the carb. Could the PO have the cam degreed? +/- . I pulled the No 1 plug and it seems correct with the mark on the wheel. I'm lost here. I was running out of light.

I can get it to idle OK in park @ 650/700 rpms but then in gear it stalls. So If I bump the idle to 900 in park it'll hold 600/650 in gear but it wants to take off on me.

Could this be a vac leak I cant find??? My manifold is vibrating between 16 and 19 Hg


I'll have to pull #1 again and check it. Is there any reason the timing could be so high??

thannks

bob

Mine was doing a similar thing on me. As instructed I tried running it off the man vac line just to see. got it to idle 850 @10║ like that. switched it back to ported to see what it would do and it was ok with a slight idle adj.. ?? seems to like 12║ a little better but we'll let some time pass as it's a fresh build.

http://www.centuryperformance.com/vacuum.asp maybe this will add some advise on the vacuum...

Just a quick up date.

The timing is set at 15btdc I hade to crank the idle up some. TDC is TDC I rotated the enging and man that piston comes up high in the hole.

So, I'm thinking I'v got a vac leak somewhere?? I replaced the booster line, the dist line, the manifold vac line, and the short line from the manifold to the hard line to the tranny.

I hosed down everything around the carb and vac lines with carb cleaner. Is there a soft vac line at the tranny??? Or the modulator?????

It''s idle is at 850-900 and drops to 600-650 in gear and doesn't surge in gear anymore but it's still not right.

the vac measured from the manifold port at the carb "vibrates" from 11 to 17 at idle. But give it some gas at she sits rock solid at 20hg???? Edlebrock 1405

Thoughts???

Hey Bear, I have a siamese mauser in that cal. one of my favorites.

Just a quick note...Is the carb tight to the intake?

RJ, Best I can tell. I poped the carb off and the gasket was dry/clean and like new. I won't overtighten it cause I've broken ears before. There was no change. I think I'll stop but the parts store and pick up a new one anyhow. They are cheap.

I do know the PO had this carb off the truck for a year or so and running on another vehicle. That gasket is a good place to focus. I really thought the carb cleaner would bring that out.

thanks,

bob

I think it was Bear on another thread that mentioned using an unlit propane torch turned up just enough to hear it. Run it around the intake edges and carb base, other areas of concern and listen for a change in RPM..
