Eric and I started assembling his engine last night. We started by removing the sharp edges on the pistons.

Before:



After:



Then we checked the piston to wall clearance on each cylinder using the piston that was going into that cylinder. All were a very tight .005.



We then installed the main bearing and plastigaged the crank mains. All were around .0025. Next we installed a rod and piston and checked the block clearance for the stroker crank. The tightest clearance was .107 so we didn't need to clearance the block at all. We then took it back apart and cleaned everything with soap and warm water and then installed the crank.

Today we are going to plastigage the rod bearings and then assemble the pistons and rods, install the piston rings, and install the pistons. Eric will post up more pictures later.

Will removing the material from the pistons require re-balancing?

We didn't remove enough to make a difference in the weight. If we had removed a lot of material then I would have it rebalanced but not with the little we did.

However, we did run into an issue today and I'm glad we did because I discovered I misread the plastigage yesterday. Today we started by installing the pistons on the rods. FYI, full floating pins with Spirolox are a pain the ass to install. Just ask Eric. So after that we checked the bearing clearance and discovered it only had .0015. That's when I realized I misread the Plastigage yesterday when doing the mains. On the mains we only have .0017-.0018. We double checked just to make sure. So we need to get some new bearings that are undersized .001 so that we have the proper clearances. The good news is that we should be able to get them Monday. We also checked the side clearance between the rods which is .0015 so we are good there.

You think those locks are hard to install, try removing them

No thanks. I'm hoping the engine will last a very long time so it will be years before we have to take them off. Eric was supposed to call CHP Monday about the bearings but he didn't have time so we're on hold right now.

When we checked the piston to wall clearance we numbered each piston with the cylinder we checked it in. Then when we were installing the rods we made sure the rod and piston were facing the correct direction. We also wrote down which rod number was for which cylinder. So I know we won't have to take any apart.

Eric spoke to Coast High Performance today and the Ford engine specialist said that the clearances we had with the plastigage were fine because it isn't very accurate. He said that it usually reads on the tight side and that if we were seeing .0018 with it the clearance was most likely around .0020-.0022. He also told Eric if he was still worried about it that he should take it to a machine shop and have them measure it but that it should be fine. I think Phil has a micrometer that measures ten-thousandths so we'll probably get it from him while he's back for Thanksgiving and then measure it ourselves.

Oh i did the same thing, even the rods are numbered along with the pistons. Just that one distracted moment and i realized i put the rod in the wrong piston.

Well we haven't updated this in a long time. We ran the bearings as they were and have finished assembling most of the engine. Also, this engine is not going to be NA for a while and Eric is going to add the supercharger at a later time. I dropped the engine in yesterday and we are going to finish it up at the end of this week. Here's how it sits as of yesterday.

Im sure Eric could score a supercharger kit for cheap. They are all over the place right now, i know i scored big time but if he isnt afraid to lowball the shit out of people im sure he can too. What rockers is he running? I know most rockers dont like the stock valve covers.
