Thanks, I guess there isnt much of a difference between -5cc and -6.88cc. If I have to modify the heads or go with another set with specs that will keep me out of detonation hazards, I will. I'm moving on with the rest of the build and will fugure it out later.

I'm getting ready to order my rod and main bearings and could someone explain to me why are there different sizes such as .010/.020 and such. What size do I need, will it be standard size since I am using a stock crank.

If you are buying a new crank, the bearings should be standard. It's always a good idea to mic the journals first, before buying bearings in case you needed to tweak the clearances.

I don't know what's funnier, some hack charging 85 bucks to bore and hone a block or someone selling a machined and "balanced" crank for 60 bucks....

Are these "vortec" (i'm even more confused now) blocks made in usa or south of the border?


2) What about these long blocks? Where were they made?

For example:

Both of my Gm 350 blocks one a older style two piece rear main seal and my newer style vortec 880 block are both hecho en mexico and both actually said that on the crate box and the engine block themselves. As far as I know there crate motors are put together in mexico as well but I can't guarantee a hundred percent on that one as I have heard parts made in mexico but assembled here so take that for what its worth. From reading up on there short block and long block combos there actually really put together well according to skip white off of ebay who sell them and built different combos with them. Almost of all the GM blocks have been made in mexico for quite some time.

I just went out and looked at my 880 Vortec block (made 1997) and I don't see a country of manufacture anywhere on it. My 727 TBI truck block ('92, not roller cam provisioned) was made in Canada.

Is it visible w/the trans attached or is it inside the trans 'cave'?

Why would a crank's journal be .010 under. How does this affect the performance? Or is this just a crank that needed work done to it, so you need to get different size bearings for it?

Put your earlier question regarding the different size bearings that are available together w/THIS question of why a journal would be made undersize. Now what do you get?

Undersized journals combined w/oversized bearings (i.e. bearings made to correctly fit an undersized journal- the bearing would be thicker than a standard bearing, right?) should equal what?

I understand that bearing are made to fit the actual size of the journal but are there brand new cranks that come from the manufacturer undersized? If so why?
