Nice little machine.
Looks like it came with a fair amount of tooling.

Every once in a while us old farts have a few days strung together where we actually feel decent for a bit. It is amazing how much you can get done when you don't feel like chit.
yes it did so hopefully my buddy will be able to check it out so I don’t buy more stuff I don’t need. He threw the big head pressure machine and all the plates and I bought a portable one from him for 100.00. He offered me a nice tumbler pretty cheap but I probably wouldn’t use it since I’m not getting into the head building business
One done one to go. Doing these at a friends and maybe family rate so I’m not getting rich on this job.
She runs an average of 6.50 but has been in the high 6.30’s and would like to run there more often. I hope this helps. Now a Ford Super Victor for her Dads 5.80 engine.
Nice work, John. Very nice 
Did I say how much I hate doing Ford intake manifolds. Especially when people use those DAMN scotchbright to clean their intakes. It took me probably as long to layout than it did to gasket match one side. Ford intake gasket holes are oval and very time consuming to locate right.
I see alot of that scotch Brite crap at work on aluminum heads, it makes setting up for surfacing a little more complicated .
In a couple months I'll attempt to burr finish the intake for my 470, I'm putting a dominator onto a 4150 with 3 or 4 inches of spacer, so I need to blend all that in as well.
Might have yellerrose help me with the burr finish
Though he's good at it.

I buy WD40 buy the gallon and usually mix it with transmission fluid. Or if I’m out just plain transmission fluid.

What kind of gains can you expect from that type of porting work?
I can’t give you an honest answer to that because there are to many other factors and I didn’t do the heads to match them up. On an intake like this I really like to use a one inch spacer to better shape the runner entrance. For 150.00 I couldn’t go to crazy so I hope she gets where she wanted to be. I probably wouldn’t touch an intake anymore for less than 350.00 but these two are possibly going to be family.
Family? Are you going to give a refund at the Chapel?

Fair enough. Thank you!
One more question in you don't mind. What goal do you have in mind when porting an intake like this? Is it to minimize any possible restrictions, or does it go further than that? For instance, do you try to make the port a certain shape, etc.?
when I first started flowing heads, then intakes it rattled my brain to see a set of heads I spent hours on loose 40 or more cfm when I bolted an intake on. Then I did a little track testing not so much back to back but with the same combo. I always write down weather conditions on my slips so I have something to go by. I never measure ports or runners, never did. By now I look at an intake and get an idea what shaping I am limited to. Then go for it. This intake here to get some shape I had to push the divider down away from the carb flange as it ran the whole way up. With a burr that’s a tricky thing to do as it wants to jump. If I had a mill I would have removed more to allow more shaping but again I wouldn’t have done it to these for what I’m making on the job. So bottom line when I hear someone say porting an intake isn’t worthwhile I know better. But some guys think a “buff and shine” is porting.
Well I got a late start on the second intake (Super Victor) so when you start late you gotta work late. All 8 runners are gasket matched and all 8 runners are 95% done. Football playoffs games and a big snowstorm heading our way so I wanted to make some progress
Finished up the plenum tonight. Not my best work but trust me the price was right. Before working the plenum
