289

[jwboner]

You must have done your mods to the bottom end. I wouldn't trust the weak stock rod bolts to anything over 7000 before parts start flying off. The 289 crank does like higher revs but the 289 is 2.87" stroke and 302 is 3.0" so there isn't much difference. A 302 with good main and rod bolts with a stud girdle will let the 302 rev way up high and still give you the marginally better low-end. No other mods are necassary,same bellhousing bolts up. I know a lot of road racers that get late model 302 and put the 289 inerts with well assembled bottom and rev to 10,000 easy, but MUST be done right.
