I wanted to do a quad 4 swap for a while but went another route instead... What did you use to polish the compustion chamber? And did you use those cutting bits in a dremel? I plan on a bunch of porting and polishing real soon and I need to buy bits for a dremel or an air grinder (I have both) And Im just not sure where to get them |

This is the porting kit I got years ago, I forget where the aluminum cutting bit came from, the carbide bit was gotten at local tool-mart type place, they usally have them cheap(er) they work with a drill or air grinder.
I also used a bunch of small flap wheels, for the die grinder too.
I polished the combustion chamber with a small 120 grit flap wheel in a dremel, then finished with the cross buffs that come in the porting kit.
Air grinder works best, drill also works just goes slower, dremel is good for small/tight spaces, otherwise way too slow.
First get a porting kit it has most everything you need, if not everything.
Carbide bits take out metal fast, so only get one once you feel ok about grinding/porting. Practicing first on a junk head is always best.
The aluminum cutting bits cut aluminum very fast, only use when you know what you are doing.
Flap wheels are great for smoothing, and come in different grits.
Here is a Great guide on porting. http://65corvette.nonethewi...echnical/diyport.pdf

On to more pics.
There is a check valve it the corner of the block, to keep oil from draining down so it has oil on start up.
Sometimes the ball can come out so make sure it is there.
The block.
The oil pump and windage tray.
The windage tray and oil pump bracket.
The oil pump.
How it lines up on the crank.
The crank and rods. 5 main caps and its only a 4 cyl. And 2 counter weights per piston.
The end plate cover, with rear main seal in it.
And where it goes.

The pistons.
The pistons have floating pins, GM really put alot into this engine. The can be removed without a press, only a clip on each side holding in the pins. nice.
The pistons all weigh within a gram.
But one of the rods is 15 grams overweight from the other ones.
So I have some balancing to do.

I've been reading the crap out of the links you gave, and more. I'm officially excited about the Quad4 now, I hope you're happy! 
You're not exactly shagging around, keep up the good work!

I'm getting there, this swap is comming right along. The closer to being done the more excited I will get. Don't get me wrong I am having a ton of fun doing this swap.
I got the balancing done now, so now all the pistons, pins, rings, and rods together weigh within 1 gram of each other. I didn't feel like going down to 1/10 gram as there is prob that much oil or carbon left on one.
15 grams is alot to take off these rods, not alot of balancing pads on them. So after grinding and smoothing off the whole pad on the bottom,.......
I decided to polish the beam to get the last bit of weight off. It even makes the rod stronger too. I would polish the other rods, but one, not needed for the power I am going to run and two, it would make the other rods too light for me to be able to match this rod to them.
Now all good.
I tried to make a setup so I could balance each end of the rods, (I know a bit of overkill)
I tried many different setups and just could not get consistent readings, the static friction wouldn't let it happen. And after balancing the rods I see there is not really a balance pad on the small end so it would not have worked too well anyway. Here is one of the things I made to try, prob would work if I had a bearing on the big end. It did work to an extent but not good enough for me.

When I pulled of the trans from quad no2, I found this carnage.
The trans seems to be ok, which is the good thing as I still need to figure out what trans I am going to use.

Nice clutch!!!
The one that is on my old motor is practically new, its a stock replacement, nothing special.
I'm really surprised that ONE rod was so much heavier, was there any obvious reason? Like a visibly chunkier rod beam? The rods and pistons did all come out of the same H.O. engine. So something has to give.
Good job on the head, it looks like a winner.
I'll be in NY for the next week and a half, If I had a chance I'd be up at the shop, I wan't to see this come together. I kinda want to see WTF is up with that 3.94 transmission. I have a couple sets of good used synchros on hand. Maybe make one nice transmission? I also have those brackets I took when we pulled the swap. I MAY not need them in the future as I'm going F23 with the L67/32 and the F40 on the LQ1. Just seems like the right way to go these days if you want anything powerful to last you know?

Oh, and about that rear mount. That one has a little story...
Originally, I was trying to fit a rather large muffler between the cradle and the trunk wall. I made my clearance on the cradle, and it intruded on the rear transmission mount area. So I did that little piece of metal to hold that one funny looking mount. If I were to redo it, I'd probably have not clearanced the cradle, used a stock mount on the cradle, and a custom low profile mount on the transmission. That mount is way hard compared to the other two rather soft mounts. But it HAD to be ridgid to keep the transmission from smashing the cradle in that one spot. This setup is mounted as LOW as was physically possible, and still straight and level. And it just manages to clear the torsion spring and decklid. It is a tall engine!

The one rod looks exactly like the others, but a half an ounce is a big differance.
I was planing on useing your clutch, cause it looks fine.
I will be going through all the trans I have to choose from to make a good one. The trans from the 2nd one seems like a good 3.94, I might go the 3.61 if it comes together right. For MPG.
