I know some of the folks on this site like anything Scania since they had the connection with Mack, hope some of you will get a kick out of this story. Hopefully someone can help fill in the gaps as well since there isn't much information about the Case-Scania partnership on the web.
During the mid 70s and early 80s Case (that's J.I. Case before the Case IH merger) needed a bigger motor for their new 90 and later 94 series 4 wheel drive tractors. Their own 504 motor was great when it was making 130hp but wasn't competitive when it was bumped up to over 260hp. Case decided used the DS-11 inline 6 engine in their 4890 and 4894 models while the big 4994 got the 16.2 (866ci) Scania DS-14 V8 engine. Unfortunately it was not a very big hit with farmers as they only sold 224 of them over 3 years of production (84-87). By the late 70s most farmers had a bad taste with V8 tractors, mostly due to the less then stellar V8 cummins used in many different makes and models. Parts are near impossible to find for these beasts and out of the few that are left some got a Cummins engine swap.
I find it sad that not many know of the 4994, it was the most powerful tractor J.I. Case would make before the merger, and it took a few years into the merger before they would come up with a tractor crossed the 400hp mark. I'll post a few videos and advertisements so listen to that V8 roar! It's got the same spirit as an E9 alright!
