Basically, from late '63-'67. Here's some info on the K code 289 HiPo, just scroll down to the info about it: http://en.wikipedia.org/wiki/Ford_Windsor_engine . JohnWow, big differnence. Good thing you pointed that out. I didn't know that. Like a 72 Q code isn't the same as 70 Q code. What years did K codes = 289 Hi Po?
I had already read about the differences between HiPo and regular 289's in the fantastic book Ford Performance by Pat Ganahl, and other sources too, but wasn't sure exactly which years it was made. What's surprising to me is that a K code in the 64 Mercury wasn't a HiPo. I know you can get fooled if you don't know what you're doing. Thanks for the interesting link. I had never heard of the entire small block family (221-351W) being referred to as "Windsor's".
Wow... cool memories, no wonder you turned out to be such a "motor-head"!Me and my brothers had a 65 Mustang coupe K code 298 Hipo we use to thrash on around the farm. It was pretty rusty and we never had it on the road (except to do burnouts). Used to drive it around the hay fields like the duke boys. In the lake 70's my dad sent it to the boneyard for $50.00. I was about 12 and have no idea it was "that" special. It was a fun car that I learned to shift in and you couldn't blow it up. We tried with a few missed shifts.
