Where can i track down 4 bolt main caps for the 400 block?
Are there some aftermarket ones offered, or is it time to break out the coveralls and go junk yard hunting?

You will be hunting a long time because Ford didn't make 4 bolt caps for the 400. Thy were available on some 351C engines but used a smaller main journal. Stock 351C caps are not worth modifying.
Milodon makes angled 351C 4 bolt caps but they are not cheap and would have to be modified for a larger bearing and fitted. $$$
Several aftermarket caps are available for the 351W but have a different bolt spacing. Shazam used a 351W stud girdle, modified to the 400 bolt spacing.
http://www.f-p-s.com/ makes 351C stud girdles. They may fit a 400.
I haven't checked the bolt spacing from a 460 yet.
All replacement caps should be align honed for proper fit.

BrainS is right and I didn't know about this place or I'd had gotten one from them.
http://www.f-p-s.com/ makes 351C stud girdles. They may fit a 400.
But what I learned so far is the bottom end of a 400 is very stout.
It handles all the power I built so far with out letting go.With only the addition of a Stud Girdle.

If it'll handle 800 HP, i guess all i need is the stud girdle also. I have one somewhere in the shop, just a matter of diggingit out.
Thanks for the help.

[updated:LAST EDITED ON 18-Oct-02 AT 10:17 AM (EST)]I think this is the place you meant. I saw 351C caps, but you mentioned they could make the 400 center caps for $285?

Pro-Gram Engineering (http://pro-gram.com)
responded to me with a "Yes sir, we sure do" when i asked if they make 4 bolt caps for the 400.
So my options just opened up some more.
I wonder is doing a short fill of hardblock would help this engine survive some more upper RPM's?

[updated:LAST EDITED ON 21-Oct-02 AT 07:25 PM (EST)]Please tell me what a "Stud Girdle" is. Is it the same thing as a windage tray? I looked for a pic but couldn't find one (-:.

OK a Windage tray is a sheet of steel that covers the crank and reduces the windage to the oil.
A Stud Girdle is 3/8's to 1/2" thick Blanchered Ground Steel that attaches to all the main caps studs to make them one .

>special to do?
It was pretty easy all I had to do was move the holes out about 3/16" on each side and then do some clearancing for the rods and add some spacers to clear the cap humps .....
