Well finally have all my parts and block back from the machine shop. Started the build this morning. Got as far as installing wrist pins and connecting rods on the new pistons, installing the crank and doing the measurements on the main cap bearings, filing the piston rings for my particular application, and installing 3 pistons before i started to have problems. I have now folded one oil consumption ring and broke one of the compression rings. So now im back at a stand still on the engine build while i wait for another set of piston rings to get to me.
But as i promised i took a few pictures of my build up so far. A picture of me checking piston ring gap, one of the crank installed, and a picture of the motor with 3 pistons in it, and one of the rings being filed for those who dont know there is a tool.
I was hoping to get it up and running by tommorow but it looks like the motor had different intentions in mind. What can you do sometimes it just the way things go. There will be more to come of the build and hope everyone enjoys the post.

Well im not sure what h/c/i is so i wont answer that question yet. As for the rings you were half right. The rings did start to slip out of the bottom of the ring compressor. The other half of the problem was the machine work done to the block. The machinist who i had prep my block didnt cut the top of the cylinder at a 45 degree angle so the rings had a little help going in. He did cut them but didnt do a good job. So the other three pistons i had that havent broke yet i installed them only after i took out my clylinder hone and made a better angle for the rings to go in. After i did that no problem. So as of now im waiting for another set of rings to where i can start back up. So far i have 6 of the 8 pistons in, camshaft, one of the heads on with exhaust manifold on, timing gear and cover, and both motor mounts. At this point there isnt anything eles i can do until i get my set of rings which in town they wanted $330 dollars and i called up the place i bought the stroker kit from and got it from them for $102 plus shiping. So that worked out but i wont see them for a few days. So hopefully by this weekend i will be able to start her up.
And i have decided that my car is now a girl...........
The more money i feed her the happier she is!
I would also like to add that this post is just to let people know what is involved in doing a stroker motor. There are a lot of things i did that i didnt take pictures of like checking clearences on main caps and cam bearings. This is by no means a guide so you can do it yourself.
The pistons i got were probe pistons made for trickflow heads. They are forged aluminum. I had a set of these before and had the same problem and had a compression ring break doing my 347 stroker. This time its the oil ring and a compression ring and nobody in town has a set of rings for those pistons. Figures.
Trick flow track heat heads, trick flow stage 1 camshaft......damn smog! the intake is the stock cobra upper and lower. I would like to put something different on but i want it to look like a cobra and try to keep some of the stock cobra equipment on her.

I paid no attention to you being in California. That Sucks, make me enjoy living in the County I live in, since it has no emissions testing. Opens up a whole lot more possibilities. Good Luck on your build man.
What piston rings are you using? What Main and Rod clearances did you shoot for?

Moly rings, the center beating 1k of a inch clearence the out bearings 2k of a inch. Regardless of who makes the motor i stay within ford specs. 2K of a inch is bor belt pull on the out bearing so you dont wear out the bearing prematurely right along with the out beating since pressure is applied by the trans.
Well got the second set of rings today and everything went together great. Just need to drop it in the car and bolt everything up and see how she does.
maybe im wrong on that and should give it a second look. May save me some trouble down the line. Thanks for giving me that bit of info makes me wonder if i looked at it wrong or had some other thought in mind.
