460
06/18/2003
Update, 6/18/03
Added some links below to help you build the best race car you can. Still
havent had a chance to race my car, but it will be soon.
Update, 3/22/03
The SCJ cast iron intake is disruptive at idle. I found it ran better with
the air cleaner installed. I opted out for a Stealth Manifold from Summit.
I did some searching and that appears to be a good choice. I also found out that
the throttle cable is a little short. It will reach the carb but it's connection
location on the intake manifold puts a strain on it. When I find a
replacement I'll post it.
I decided to use the brackets for alternator and power steering from the
Mercury. The bracket makes the pressure power steering line about four inches
to short. I obtained two couplings and a connector, then built a short
piece of metal tubing to extend the hose.
A friend gave me a couple of mufflers to install, since they had pipes
attached it would save me a little money. I wish I was there when the
muffler shop started my car. They said I wouldn't believe all of the Mouse
House material that came out of the exhaust. I guess that's one way to get
a (Chevy) mouse. :)
The 850 Holley I purchased used didn't have any accelerator pump
shot. I examined the carb and found a piece of bowl gasket blocking the
fuel. I also noted that the primary jets are "86's". We'll see
how that goes, I think they are suppose to be 80's?
I purchased a new battery with 1000 cca, I'm still running into a little
problem hot cranking. I'll look into the gear reduction starters in the future.
I tried the smaller 5.0 starter but it grinds when cranked.
I seen on a couple of web sites that the 460 will run out of oil. I
guess it doesn't return very good from the top end. If I plan on racing it
long I'll have to upgrade my oil pan.
Update,
2/5/03 If your using the 76 Mercury Engine and Transmission you'll need a
48" inch Driveshaft. That is center of u-joint to center of
u-joint. Since I didn't have an original Mustang Driveshaft I am
cutting down one from a 1992 Thunderbird.
I have tried to use an older
battery rated at 625 CCA I will tell you that I would recommend at least
825 CCA or better. I anticipated at least 9:7-1 Compression with the flat
top pistons, but what a drain. Another option is to use a 1992 5.0
starter. The starter is smaller and easier to change if your running
headers. The late model starter has a solenoid on the starter so there isn't a
need to run the one on the fender well. Considerate time would be needed
for this conversion so I'll wait to a later time to do it.
After almost
four years in the making I finally started on my project 460. Since I only
paid $300 dollars for my Mach1 and was given a 460 complete, C6 and a set of
3:50 gears, it was time to put it all together. My goal is going 12 seconds in
the 1/4 mile. I understand that 11 seconds are not too far off from what I
am building. At the bottom of the list I'll give you links that are really great
if your thinking of going 460.

Update, I picked this Summit cam
because of the wide torque range . If you add a good set of headers
and 1050 carb you can expect more gains in higher RPM. This engine package will
welcome a 125 HP NOS Kit and still pick up the kids after school.
