I was going to sugest that. I have run a lot of engines with sleves. Also I think I'd get the block just to have it you never know what will let go later.Quote:

We picked up the spare block tonight, it looks pretty good and has never been bored. There is a machine shop about 100 miles from here that has a pretty good reputation among the Mustang racing crowd and seem to put together a pretty good motor. I think we are going to use them to machine this new block. If it were my engine I would sleeve or see if it could be honed oversized, but he is afraid of doing that and still having issues.
Since it is Dan's money I have to go along with what he feels most comfortable doing, and he has pretty much had it with the block and heads that were giving us trouble. I can understand how he feels, he has 4-5 years in building the car and more money than either of us care to think about, and the only problem so far has been the engine. He just wants to make sure this one is done right, so it looks like I will be hauling it up I75 for him and dropping it off.
Is it best to take the pistons we are using along with the block so each cylinder can be honed to fit each piston? Or don't they need them to do that?
Don
well if they do not ask for your pistons keep hauling it north on i 75 :)
That's what i was thinking , sleeve that bore and get another life out of that block and buy the other block , oil it up ,and store it for later ,Quote:

They also balance engines there, so we will have that done at the same time, which means I will be hauling a lot of parts with me.

I just called Jegs to see what piston rings we used when we put the engine together 3 years ago (I didn't remember). They said we used Sealed Power E243K40 rings, and Sealed Power says those are chrome moly rings. They tell me they like.004 clearance per inch of bore on the top ring and .005 clearance per inch on the second ring. Do those numbers seem reasonable to you guys or should I go looser?

Take the intake manifold to them as well. They should be able to make sure that all the angles line up.Quote:

It will be a lot of driving to get all this done, but if it means getting a good machine job it will be worth it. Every time I talk to someone down here I hear more bad stuff about the machine shop I had used for years, and we have certainly had our own stories to add to the pile.
