Just finished my winter project today (Edelbrock E-Street Cylinder Heads). Just finished timing the engine and I discovered a minor issue with distributor vacuum canister and the right hand ignition shield bracket. Only thing I can come up with is buying a new bracket and drilling a hole or reclock the distributor. I'd rather not reclock the distributor if I can do something else. Anyone have any ideas?

Looks to me like you could grind off the lip of the bracket so you have a straight shot on the hose

Pull the distributor up, move the gear 1 tooth and reset your timing.

Hi s,
I believe typically the distributor is clocked so the advance can and it's vacuum hose come around the rear of the bracket for the shielding.

Hey Sunflower,
To me it doesn't look like you have the correct right side shield bracket. Even though I have a 73' I'm pretty sure the 72' bracket was the same. It's curved to let the vacuum hose clear. Is that an edelbrock intake?
Just a thought. Here's a pic of mine?

Hi Tooch,
I agree that the bracket is typically mounted under the second from the rear manifold bolt?….look closely at s's photo.

Alan

Oops!
Yes, I see it now. He's using the correct bolt. Maybe the bracket change will work for him. Made the correction above.....I'm slipping Alan

Hi Tooch,
I hope s turns the distributor.
There's no real reason to cut the bracket.

It'll be a little easier to set the dwell too.

Me too Alan,
His is facing more forward than ours, using the end of the valve cover as a guide..
I just sent you a PM!

I'm having a fart here. Won't that knock the distributor rotor off of the #1 tower of the distributor cap? Could you please explain in a little more detail?

No, of course not. Lifting the dizzy to re clock it 1 or 2 teeth doesn't change anything, just have to re set the timing. Keep in mind the oil shaft WILL NOT BE LINED UP so it won't drop back in. Stick a long screwdriver down there and move the shaft a little.

Thanks for all the replies, gentlemen. I appreciate it.

Loosen the distributor, turn it one plug wire plug length clockwise, move the wires 1 plug to the right.

Done..

I just had a lightbulb moment. So, if I move all the wires at the distributor cap 1 tower counter clockwise, mark the side of the distributor housing with the new location of #1 tower, pull dizzy and turn rotor 1 or 2 teeth clockwise, drop the dizzy so rotor lines up with the new #1 tower, I should be good to go. Correct?

I am wondering what the tach cable looks like is it in a sharp angle. He may have to reclock the distributor so the tach cable is not in a bind and that may solve the vacuum line.

sunflower 1972

Tach cable right now is good. Has a nice smooth very gradual bend to it.

BLUE1972

NO - you don't have to pull the distributor, just turn / move it 1 plug wire clockwise and move the wires I wire counterclockwise. The rotor will be on the same wire as before the move.

Doesn't matter where the rotor actually is... for illustration..
looking at a clock - if the rotor pointed to 6 oclock, rotate the distributor so 6 goes to 7's (o'clock) position. now move the wire at # 7 position to #6 and the rotor still points to #6. follow all the way around wire by wire and you are good to go. #8 (o'clock) wire position to #7 (o'clock) ..... last will be 6 to 5.

2nd this.

the right way would be pull dist. advance 1 tooth and retime.

the easy way, leave dist. seated then rotate all plug wires, 1 plug over.
loosen dist. and rotate 1 plug over.

con's : your plug wires will not be in the expected place for next mechanic.
Pro : easy way you do not have to pull the Dist.
