Once the initial porting is done, you can polish things up by using a powdered cleanser like Comet or Bar Keepers Friend. Makes it look like a mirror in there. Just did mine, runs a little rough now but it is getting so much air now is why. Need to tune it now or just run some sand through the injectors to open them up a little.

Wait, which sand blasting media did you use??
Damn man, I hope you didn't use the plastic media or the silicon carbide media! You have to use the crushed glass grit or glass beads media!!
Oh man, oh man, oh man, I pray you used the glass because if you didn't, you're in for a long rebuild.
Dooooood.......even the walnut shells are too much!!

I didn't have any sandblasting sand, but I did have lots of sand paper. So I set my paper shredder over the intake and fed it sheets while my wife held the throttle open. My yard looks like a volcano erupted with all the black ash, but that's good for the grass, right? Oh yea, what does the yellow check engine, the red engine, and the little red thing that looks like a genie lamp mean?

well, i know exactly what you did wrong.
the process you used works for the smaller honda engines, but not for the large engines found in fords. to use regular sandblasting sand to port and polish the intake and exhaust in a ford, you first need to mix the sand with a lubricant, preferably 50 weight high detergent motor oil.
the oil supplies the needed lubrication, and the high detergent content helps keep the area clean.

while you are correct that we have to use 30W oil here in the northeast where it is cold, the original poster is in californication where it is warm, so 50W is required.

They said the check engine light means just that, go check and see if it is still there. Now that I have a high HP engine, they tend to get up and run off by themselves. Hood locks are a good idea.
They said the red engine light means it is now race-ready. Red means race. So does the R on the shifter. D is for Drag Race. Start in D and shift to R at 90 mph.
They said the genie lamp IS a genie lamp! I wish all my vehicles had one. Wait, did I just use up my wishes?

This is NOT fake, you just have to use the correct media!

Sure you can. All you need is the proper oil. Pour in the sand and add 10 oil for .010 thousands, 20 oil for .020 thousands, and so on. If you need to polish different amounts on different places on the crankshaft, just use something like 10-30. It will find the bad spots by itself. Or so I've heard anyway.

I always weld a bung onto the fuel rail and feed sand through it when I port and polish the intake and exhaust. This also works for carb'd engines. Note, it doesn't work as well to just pour the sand in the tank, though I figured out why.

I discovered a quick and easy way to turbocharge my engine by simply rerouting the exhaust and connecting it directly to the intake. I figured all that pressure coming out of the exhaust pipe was going to waste, so why not make use of it as boost? As an added benefit my engine now produces ZERO emissions!
