    Just wanted to list this info from these magazine tests I kept because I still own my bought new 1978 Z28. Hope this is of interest to you guys. From Road Test Automotive Entertainment in Spring, 1978: 1978 Z28 49 state or federal version with 4 speed- 0-60 in 7.9, quarter mile in 15.8 at 88.3. Car and Driver from March, 1978: again the federal version with 4 speed- 0-60 in 7.3, quarter mile in 16.0 at 91.1. I never did run mine to see what it might do; mine is the California version with 175 hp and 265 ft./lbs. of torque with auto trans and 3.42 rear end. The federal version had 185 hp and 280 ft./lbs. of torque, and if it had a 4 speed (not available in California) 3.73 rear end.

    I know that most of the magazine numbers for the Z28 from the day were done using fairly well loaded cars with automatics. That was back in the days when the automatic was almost always significantly slower (Not like today where I get busted on for getting a 7 speed manual in my Z06 instead of the faster 8 speed auto LOL). So that's why I thought with mine being a "stripper" with a 4 speed, and decent gears, with 3.73 posi, that I may have a shot -but I can definitely be wrong. This is definitely nothing more than curiosity and something to fool around with on the 79.

    Thanks, I really think I'll do it this summer just for fun. May do like they did in the Popular Hot Rodding article; advance the timing and flip the air cleaner lid.

    I drag raced my 1979 z 28 car when it was a week old and it ran 14.71 at 90-91 mph the only mods than was no air cleaner and changed the timing and some L-60 Goodyear wider rear tires no other mods. That was a my 4 speed car 3.73 rear end no t tops.

    DB Z28, that's in line with the Popular Hot Rodding article. So, do you remember what you went with for timing? I have the retro Goodyear Polysteels in the factory size, so that may be a problem.

    I really don.t remember what we set the timing to. I know we advanced it a bit The only thing that was not stock also was the rims we had Crager Fan star rims that were Aluminum. Not the steel wheels. That because the after market rims were cheaper than the aluminum wheels from the factory

    Thanks, I'll try the 6 they did in the article and see what that does.
    Wow, I just noticed in your signature that your 79 Z/28 is putting out more HP than my Z06!
    I won't let my Z/28 see that number!

    My brother had a '79 that he picked up in 1985. It was 100% stock with 65K miles, all emissions, stock exhaust. Car was a 350, auto, 3.42 gears, A/C and T-tops. After he put headers/dual exhaust (no cats) and bumped the timing at little, the car ran 14.80s on Goodyear street tires (sea level in S. FL). He may have removed the air cleaner lid or might have had an open cleaner but I don't recall.
