65-68 as far as I know
I had close to 230,000 on my 1967 289 before my recent re-build. I've put just over 2k on it since and it runs like a champ.On 2006-04-13 00:21, ujt389 wrote:
The 289 is a great engine, the origional one in my mustang ran flawlessly (I dont count the time the points went out) untill I pulled it for a built 302. Ive heard of them going beyond 200000 miles. You can make pretty good power with them too, although the stroker motors will always make more power.
What was the trap on this run?On 2006-04-13 00:19, 67Coug wrote:
Forgot to mention: As to the most horsepower out of a 289; with the right heads, etc. you should be able to easily get around 400 and still run an automatic, preferably an AOD with high stall and 4.11 or 4.56 gears. According to the horsepower calculator I found at speedworldmotorplex.com, my engine is making about 390 HP (3600# car weight, 12.82 ET). I run ported stock '65 heads.
