13.20 mph

Gremlins are pretty light. You could get one with a fairly mild 304 in the 13s with no problem whatsoever........much less a 360.....AMC or Mopar. With simple bolt on parts such as intakes, headers, carburetors and camshafts, the 304 can be anything but "anemic". The AMC cylinder head is pretty good, since a lot of pro stock head configurations through the 70s used their port technology.
