Whats the difference between a 289 and a 289 HiPo? When I got my '68 Coupe, my girlfriend's dad told me that it had a 289 HiPo, but it only has a 2V....i found that kind of funny. Could someone clear this up for me? Thanks
289 Hypos or K engines were all 4 barrel cars. They were rated at 271 HP versus about 200 gross HP for a 2 barrel (C-code). Yours is a c-code. K engines had slightly better heads, a more agressive cam, solid lifters, a bigger carb, dual point distributor, aluminum water pump, etc. that weren't on the c-code engine. I've found than many people when hearing "289" will respond "Hypo 289". They seem to think they are the same thing. Obviously they aren't. That being said there are many things you can do with a c-code to make it eat a hypo's lunch. I'm currently in progress on a project that will accomplish that (no offense to you k-code owners...take comfort in the fact your car is still stock and worth a small fortune /forums/images/icons/smile.gif). Oh and I don't think they even made hypo 289's in '68. Somebody might check me on that.

No. I don't think so. They had bigger, beefier main caps, and they checked brinell hardness on the cranks to make sure they were the best of the stock cranks...if memory serves. Another diffference was better exhaust manifolds or tri-y's on Shelbys, coupled with dual exhaust.
Actually, there was a 4 bolt main 289 block, as pointed out to me by my racing coharts over on the Boss 302 registry board. Evidently, they came with a C6ME casting (I think) and were used in Ford's racing efforts at the time. Pat (camachinist might/probably knows more about this). As far as the Heche en Mexico block, it wasn't a hipo - have seen several 302 2V sporting the Mexican blocks.- just the way they manufactured them.....
I've heard that some prefer the Mexican blocks because they supposedly were cast using a higher nickel content, which was supposed to make the block stronger.
