I finished all the tear down to day hope to sent to the shop on Tuesday.
from there i will post what i find.
If you have to get a crank anyway, why not consider a stroker kit? I know a 302 can be taken up to 347 cubic inches. I'm not sure what you can do with a 289. Lut us know how it turns out.
Just a note, I think the 68 302 and 289 heads were different in ccs. 68 289 were low compression 63cc approx, and 302s were around 53cc. recomend 331 stroker, theyre more cost effective and increased longevity over a 347.
i have the 63cc heads the casting #C80E are for the 289 or 302 in 68
Ok, just letting you know. There is more to the casting # as in C80E-L. Because the C80E-F 302 heads are 53cc with larger valves. (didnt want you to miss out if you werent positive on what you had). You have the low comp 2 barrel heads.

The 289 heads were the same as the 2v 302 heads aside from the valve diameter. The 302 4v heads were 53cc's.
