    I love the second gear chirp. It gets her a little extra jump.

    If the Chevelle had an L79 327 instead of the 300hp engine, the outcome would have been different. Many years ago, one of the car magazines did a road test of the Corvettes with the availalble 327 engines. They ran a hydraulic lifter L79 350hp, a solid lifter 365hp version, and a 375 fuel injected one. The two solid lifter engines, (365 and 375) revved higher, but couldn't catch up in a quarter mile to the milder L79 327. If they would have run a half mile, the higher revving engines could have caught up using their superior top end, but in a quarter mile they came up short.
    This Chevelle with 300hp 327 would be a better match for the SS350 with the same basic 300hp engine in 350 cubes.
    Also, the Z28 could have done a bit better with a 4 speed. The 1970 road tests commonly timed the 4 speed Z28 in the high 13 second range.

    My new 1970 Z/28 had a turbo 400 with 4:10 gears ran 14.10 bone stock 2 weeks after I got it. I still have the time slips somewhere.
