Thanks again! I like the links, every little bit helps! Looks pretty painless and pretty straight forward.

Does anybody know offhand what size the allen bolts are holding the flywheel on and the side allen bolts on front and rear main bearing caps. I plan to pick up a few tools today and start tearing this one down. I have tons of tools but probably don't have the right size allen wrenches to fit a rachet which I will need when torquing, so might as well get them now..

also should I get the machine shop to put in all new freeze plugs while I'm doing this? I don't guess they will mess that up? They say on aluminum blocks you have to be very careful while removing old freeze plugs? I guess I need to find a really good machine shop that I can trust. I would sure hate to get this together and have a leaking freeze plug.

You can use 4.0 pistons on the 4.6 crank.


Freeze plugs can be messed up, too, so I would take the extra penny and go to a good machine shop.

Ok good deal, I'll see if I can locate a 4.6 crank and rods. and will drive to new orleans or baton rouge to a top notch machine shop.

Got any idea what they would charge for liners? I don't want to sink a ton of money in this. I may just pin these after I get everything professionally pressure tested and all checks out.

I'm bad about well if I'm gonna do this I might as well do this and since I'm doing that I guess I should go ahead and do this and after I look at the bottom line I have second thoughts about it all. So I gotta keep this reasonable.

I would add liners to it before upgrading to the 4.6, honestly. I think the 1000$ is worth the cost since you'll never have to worry about that again.

Default socket head cap screw size

ok, it's the 6 socket head cap screws holding the hub aligner to the crank that I need the size of. The allen head wrench size needed not the bolt size. If anybody happens to know that. I have a 5/16 allen wrench that seems to
fit but didn't know if is actually a metric size. Don't want to mess the bolts up. I can't get them out with the allen wrench so need to get a hex head socket to fit to my impact.
Hope I'm not being too big of a pain!

Thanks I'm going to look into that. Who does it for $1000? Not many good machine shops around here. Maybe in New Orleans.

in wrought numbers is $100 a sleeve and another $100 to install so Approx. $1600. if your going that route you might as well buy a rebuilt short block, your going to end up with the same amount of money into it.
freeze plugs or core plugs are easily done yourself especially if the block is out, use a dent puller to remove if you have one.

That's what I thought, so won't be doing new sleeves. I'll pin these to be on the safe side.

I've done freeze plugs on SBC but didn't know if there was a special technique to remove these without scoring the the aluminum. I've never changed them in an aluminum block.
I see the plugs in it have some kind of sealer around them. Does the factory put some type of off white sealer around them? or have these been changed before since they have sealer?
They all look about new but, was thinking since I will have it stripped anyway, maybe I should put in all new ones.

yes, they use sealer on them, just throw in new brass one with sealer you'll will be fine
