Originality / 69 Z28 coil bracket- Notched?

« on: January 09, 2011, 04:35:32 PM »

Gentlemen,
I purchased a 69 Z28 Original ignition coil bracket which has the correct angle to clear the cowl induction air cleaner. My question is, does the coil bracket suppose to have a notch on the top side? My bracket is a soild piece without this notch. Do i have the correct one? According to one person on ebay who is selling one with the notch, this persons claims if this coil bracket isnt notched it can cause ignition problems. I never heard of this, was the notched bracket use on BB Cars only? I am under the impression that the 69 Z28 Coil Bracket wasnt notched, please help me out. Thank You.

Originality / Original 69 Z28 Master cylinder- no power brake booster?

« on: December 26, 2010, 01:10:38 PM »

Gentlemen i have a question about my original brake master cylinder on my 69 Z28. When i bought this used Z28 it came with no power brake booster but has a original master cyliner casting number 5468309 which is a correct Z28 piece.  This car has front disc brakes. Whats going on here, why no power brake booster. Did some Z28s not have these installed with the front disc brake setup? All the brake lines going to the master cylinder are original and never have been changed or modified. Could this car have been a drum brake unit and someone may have installed these disc brakes? My Z28 is currently setup for drag racing. Could have someone removed this power brake booster because of low vaccum on the drag engine and wouldnt operate the booster correctly? I am puzzled here. Any input is greatly appreciated.
