Thanks for your comments. I think I'll try to find the entire unit. I've
installed and setup rear gears, and my general wrenching handicaps
indicate I'm just fine with bolt on's. Regarding the differrential codes,
the Chilton book also indicates the F7 as a 4.10 geared unit. I was just
looking at the K6 code because it's listed as 3200 lbs, versus the F7 code
of 2700lbs. I'd be happy with either. I'm glad you pointed out that the
was the same. You've broadened my search. You're right about the F6 unit
being 3.73, but I'm referring to the K6. I'm just passing on what the book
says, I haven't actually seen either unit yet.

I would remove the bump in the exhaust port of the heads, you don't have
to remove them to do it and it will get you an easy 15-20 horsepower

I would sure second that ! The 302 / 351 stock exhaust ports are pitiful.
I don't know HOW they run as well as they do. It only takes a little time
with a carbide fitted grinder to make huge improvements. Don't get
carried away, just take out that bump and bring the opening out to the
same size as an exhaust gasket or header gasket. And of course, make them
all the same. I would however take the heads off. It's a lot easier to do
when you can see, and move the heads around. Plus no grinding grit in the
engine. (You might also look into picking up another set of heads and
doing them )
There's been a couple of good articles on windsor head porting in the
past. I just finished a set for my 351, and they look much better now. I
pretty much used info from a Ford High Performance article from Oct, 96.
A place called A-Ford-Able Performance is porting stock D5AE and E7TE
heads with very good results. A stock D5AE exhaust port flows 114 cfm.
.500 lift. On their Stage I head they remove the bump, put in a 1.60
valve, clean the bowl area and gasket match the port. It goes to 169 cfm
.500. I know that's not 429-460 territory, but it sure beats the heck
out of 114. Their "best" head, a Stage III w / 1.65 ex. flows 179 cfm.
.500. By comparison, a "stock" GT-40 alum. head flows 131 cfm .500. So
you can see removing that bump makes a big difference. Sorry for the
length of this post, but all this is still fresh in my "Head". ( Pun
intended) Good luck Shane....whatever you decide.
