What do you mean the big end of the rods?

The larger end, the bearing journal on the rod. Your bearings have an inner and outter race (common term used on ball/roller bearing's, pretty much means the outside and inside face) Your inner race contacts the crank journal and your outter race contacts your rod journal.

Now thats the spot..and the wtf it looks like something got shaved off. should it be that way...?

edit.//

I don't understand how do I find bigger bearings..i've been looking on enjuku and they don't sell different sized ones, so do I have to custom order a set? or should I get a new crank?

You could get a new crank, but just have that one turned down and balanced. You may even be able to find oversized bearings from your dealership? Cutting bearing journals is a common thing, bearings are out there, trust me.

I mean, that part of the crank only looks scuffed up, you can't even feel it to the touch..I'm pretty new to tearing apart the bottom end so I'm not sure how to go about this..

When you buy a new oil pickup and pump, but the pickup from an S14, they have a bigger opening and were re-designed a tad.

If you want a nice running stock SR, I would get your crank issue sorted out and the correct bearings, you may want to pick up another used OEM rod for that cyl. Just a new gasket kit + ring kit and a quick hone would probably throw that thing back together nicely. Have your valve seals replaced while you have it apart too.

And the pickup bolts right up to the sr?

yeah, I might use the stock bottom end..get new rings and such, and then build a nice head, try get get some good rpms out of it.. get some cams lifters spring etc. the guy gave me 8 pistons..i have no idea which where the ones actually in the engine lol

if your going as far as to build the head, I would atleast get forged pistons. Yes the S14 SR pickup will bolt up, its going to look a tad different, it bolts up though.

Alrighty. Thanks for all the help I'm going to see how much it is to get the crank polished and such and see where it takes me! I might just get rods too and call it even..but I'll decide that later.

The last deal I got I threw in the trash, a perfectly good 4 bolt main SBC long block with .30 over bore. Had bad valve seals and an oil consumption problem due to that fact. It sat in my garage a few years so I sent it to the scrap yard, stupid me.

Your intake and exhaust cams are mixed up.

I wish I had a shed to build engines in. living in an apartment sucks can't even do an oil change without receiving a "please do not do car work in the complex" letter from the front office.
