ThaddeusW Posted December 26, 2006 Share Posted December 26, 2006 Ok trying to sort out the V8's. First off the 86x series were the first of the V8's starting with the 864. If I got this down the 864 was offered in a 250hp or there abouts non turbo and a twin turbo model at up to 325 HP and it was hooked to a triplex/quad box. What year was it introduced (60's?) Was the dynatard introduced with this engine or the 865/866?The 865 was a turboed V8 that produced 325hp and was a wide torque band so it was hooked to a 5/6 speed. The 866 was similar to the 865 but it produced 375hp (any of them aftercooled?) Also what years did they come out?Now the 998cid was the new v8 that came toward the end of the 70's or early 80's and was the predecessor to the E9 correct? It was air-air aftercooled and had a horse power range of 400-440/450. was the 998 the same as the E9? Or, is the E9 the 1000cid that was the successor to the 998? Also the E9's lowest horspower was 440 and went to 500 or did it go from 400-500? I know down under they cranked it up to 610hp and 2050ft/lbs.Thanks for the help.

rick harper Posted December 26, 2006 Share Posted December 26, 2006 If my memory serves me right the 998 and E9 was the same. HP ratings from 400 to 500 and down under they cranked them higher. The E9 was also in the US Tank fleet. Twin turbos producing around 1000HP.

Terry T Posted December 26, 2006 Share Posted December 26, 2006 The E9 was a 998 c.i.d. engine. I recall seeing 440 E9's, possibly 400's, but Mike H. would probably know best though.T.

MidniteMechanic Posted December 26, 2006 Share Posted December 26, 2006 There were 400hp E9's. I think there was a 450hp in addition to the 440hp, not sure though.

theakerstwo Posted June 2, 2008 Share Posted June 2, 2008 The first v8 i think came out in 63 and then the twinturbo was maybe 66 but the Tulsa dealer got one of the first two or maybe they got the first two that was to be had and sold one of then local and dont remember about the other one. That was a big horse in its time. Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/1921-86x-998-e9/#findComment-19453 Share on other sites More sharing options...
