patrickt,

I ended up taking my car to a local shop that has had experience with Webers and 427 ford's.

After explaining the problem to him, as you mentioned,he asked me if my heart was set on these carbs. I responded by saying yes.

He was going to suggest to switch to dual 4 barrels and I told him let give the webers a try first.

I dropped the car off with a book of all the adjustment I have already tried and with the following new jets:

50 pump jets
135 mains


He was able to get the car running good in 1/2 a day.

He has done the following:

Change plugs
Compression Test
Leakdown Test
Set timing by rev motor to 3000 rpm and set timing to 36 degrees
change pump jets to 50
55 idles
100 holders
180 air
F7 e tube
135 mains

He has requested to put in F2 etubes to fine tune the mixture.

From what he says it is a completely different motor with alot more power. Popping has been eliminated!!!

He still has the car there he mentioned the leakdown numbers but told me lets see of the rings seat
He said he is not happy with the oil pressure but he will change the straight 30 to straight 50 and cut open the filters to make a determination of that.

He is not forcing a rebuild on me, he said lets wait and see some more results.

He is not happy with the cam either nor does he hate it.

I sttill have not yet seen or heard the car so I am just preparing for a rebuild if I need it.
