Lil sneak peak on the 263 finned valve cover. Still have to blend in the fins with each other then seal and paint. Then ill move on to finishing the 4x2 intake. Ill see what kind of interest I get.

Seeing that there is not much interest in the straight eight Buick I might have to jump onto the sbc and fords. Ill make stuff for my self but thats about it. No point in 2 or 3 castings. Had plans for an affordable 16 port head and other stuff but its dead.
 
The 320 is where most of the interest is but that is pretty limited as well. Nice effort, though. A 320 crossflow head still has my interest. [Not sure why].

If im not mistaken the 263 was and is the ideal racing engine according to alleykat. I read all his stuff and went my self with that engine. I will be doing the same for the 320 soon as pattern for the smaller mill are finished.
 
price

As of now I can only speak for the small valve cover. I cant really say for sure but it would be somewhere between $200 & $240. Its a tall cover with a good thickness. Ill have to make one first to find out how much aluminum It will need. Keep in mind that I'm not commercial so I'll have to buy junk cast aluminum car parts to use as material. But most likely I'll try to keep it around and close to $200 but cant make no promises. That 320 is a few inches longer so keep that in mind and that I'll be hand polishing each one as to no burn any material off with the buffing wheel. I want this to be a piece of art.
 
I think it looks great in the satin finish. Just some sort of coating to keep the grease from penitrating. Just my opinion.
 
I may be mistaken, but the valve covers for the 263 and the 248 maybe identical in terms of physical size. I know they both use the same gasket. The only issue I can think of is the distance between the hold down stud holes. On the 248 (1940 on & maybe earlier) the distance is 22 & 13/16 inches, equal distance from each end. If the 263 is the same, it would increase the potential customer pool. I have a 248 and would be interested in the finned cover if it fits.

When I make my patterns I measure from center of bolt hole to center. The measurement I got was from the inside end to thee other and is 22 5/8. Will that work?

I don't believe that difference is a problem, the flat area for the hold down studs leaves room for slight adjustment on the holes. The length & width of the valve covers on both engines must be the same as they use the same gasket. The interior height needs to be 3.75" to provide stock clearance for the valve train. As long as those measurements are good to go, I am certainly interested in purchasing one of the valve covers w/o the hold dow​n stud holes drilled.

If I remember my numbers accurately the inside clearance is 5"+. No less. It's a tall cover. I made it that way for the guys who are running roller rockers.

sounds like a good way to go, theres many more 248/263.s out there , they can pay for the 320 covers, and may be able to get capital for a good breathing aluminum head. gggg
