Motor Build questions (clearances etc..)

[boostedbuford]

Got a quick Question

Basically the motor is a TSM build-
- I got my stock rods resized, now w/ arp rods bolts-
my question is, 4 of my caps are fine, but 2 of them are about .002, .003 thousandths off I can feel w/ my finger nail- from fittin flush-

Is this gonna be a problem?

elaborate on what you mean more "not fitting flush" where & how, a pic. is worth a 1000 words

 

[scottk]

thats .005 which is bad!.0005 i think is ok?

 

[scottk]

.0025 is ok for rods! I think

 

[scottk]

rod bearing clearance .0025 max!

 

[boostedbuford]

no my rod "bearing" clearances are fine, it the rod CAP acutually fitting flush on the rod.

I only have a picture of my bigblock so ill use it as example-

where the red arrow points is where I can feel the edge with my finger.

Take those rods back to the machine shop and show them - this does not sound right.

I would say you have the wrong bearing in there. Was the crank cut?

The problem sounds like cap shift, the stock buick rods don't have a real
positive way of centering the cap to the rod . I would try loosing up the
bolts just enough to be able to slide the fork and cap opposite each other
until they are flush. If they won't line up then take them back out and
inspect in greater detail.
