    Holden 186 top speed?

    Just out of curiosity as mine still won't be on the road for a while, what would be the top speed of a 186 Holden motor in a 1974 Series III with 4 speed box? I was just curious to wether it could get to 110km/h on the Highway? Also the head was replaced not too long ago (maybe around 10000km's?? Not too sure)

    Four and a half thousand revs in 4th gear will give you about 120 kmh....but thats a lot of noise.

    And a lot of shakes, rattles and rolls and if and emergency stop is required you'll need about 3 1/2 aircraft carrier lengths to come to a halt.

    You won't find me on: faceplant; Scipe; Infragam; LumpedIn; ShapCnat or Twitting. I'm just not that interesting.

    And a rapidly descending fuel gauge! I wonder how long a 186 will last running at that speed? There is a good reason why a large proportion of Holden conversions had overdrives.

    just use a crumple zone, that'll pull you up a lot faster.

    At 110 Klm/Hr you getting close to the top speed of a Holden powered Land Rover, which is directly proportional to the thickness of the ear protection you are wearing.

    At 110 Klm/Hr you are getting close to be selected for the next James Bond movie, to be used as an extra to lay smoke screens!

    At 110 Klm/Hr you need to be following a semi to pull up, the semi has a slightly longer braking distance.

    At 110 Klm/Hr you need to wear a freezer suit, to keep the heat out.

    At 110 Klm/Hr you need to watch very carefully for speed camera's, in 100 Klm zones!

    At 110 Klm/Hr , how do I know all this?

    Yeh and you will probally buckle the steering wheel because you will be standing that hard on the brake peddle!

    Meh, u all make jokes about the distance it takes to stop..... Unfortunately it's all true

    My ol s3 had 202 red, with overdrive, 30 x 10.5's, 3.55 diff, and top speed I got was 140klm/hr... And a whole heap of grey hairs too

    My current s3 wagon with red 202, 4spd no overdrive, same tyres, same diff I got the other day 120klm/hr.... And I think I would of lasted maybe 5 mins, not sure whether I would of run out of fuel first or if the engine would of overheated....
