The last post got me wondering how many folks installed 6-bolt 289s or 302s,
but kept their 5-bolt 4 speed. I'm close to pulling my 260 as part of the
resto teardown. I would rebuild it, but the devil has me thinking that if the
money's going to be spent, should it really be spent on a 140 hp 260? From
the cyl head id discussion, it sounds like tweaks to the 260 are limited other
than going the F4B/4bbl and header route. Pls correct me if I'm wrong.
I'm SURE this has been covered, but can the list describe some of the
challenges to a 289/302 conversion? Adapter plates are available (cost?
sources?)...but if you install the adapter plate, what else needs to be
modified? How rare are 5-bolt 289s?
Is that same devil going to be whispering, "Get a T5"?
Thanks for your thoughts...
