It would be nice if that 'billet' block was spoken of as a billet casting or some such. There IS such a thing as a real billet aluminum block available from a concern here in Metro Detroit, that is carved from a proper-sized 'brick' of aluminum and, within reason, you can specify some of the dimensions. But the minimum starting order is for three blocks at 15 grand apiece. so you'd have to start with fairly deep pockets. (Starts y'ur head agoin')

Easier to buy one of the true billet 426 Hemi nitro blocks but get the deck drilled for a Ford bolt pattern, ala' a 385 series Boss engine!

I just buy FL1-As off the shelf, or the Wix part.  Even at 72 lbs cold never had an issue.  Yet. 

I have a nice straight fine tooth file that I clamp in a vice and manually file rings.  Been doing that for years without problems.  I just push the ring gap down the file, never pull.  I count strokes, then buff the edges with a fine Arkansas whet stone. Yea, I've looked at all the ring filers and some are really nice but I just can't seem to justify the outlay.  IMHO there's a kinda "zen" to hand ring filing.   

SOLD!
What kind of fanatic spends $700 on an Aviaid oil pan and pickup tube for their 63 Galaxie? This guy^^^
As a result, I have for sale a new, installed on engine, but never ran, black powder coated milodon number 31130   7 Quart Street and strip oil pan and matching pick up screen to sell. It is like new, and was installed with studs and nuts so the rails are as perfect as when it was manufactured. If Purchased from Summit, who has them in stock, currently with 7% sales tax would cost you $459. Since I won't be needing or using it, someone that wants to send $250 my way this afternoon or evening, can save some bucks on it Saves $209 that you can invest in other things for your engine. Not everyone is in love with their Galaxie, or has the means or budget to buy it a $459 or for that matter a $700 Aiviad Pan, But, If you been wanting to buy one of these now is your chance to save some money. I forget what the powder coating cost, I think it was something like 60 or $70, but my loss is your gain. Send me a message, fire up your credit card, and save a few bucks! Oil pan and pick up tube will be pulled this weekend and sent out on Tuesday. I'm covering the shipping at the above cost unless you live in California, then add $30.

Well, it's a C8AX-D cam...probably not the cam we need for a 428 PI, C-6 highway patrol car

The C8AX-C would probably be pretty good though, I think that is the same grind they used on the D2OZ 429-460 PI cam.
