Hello everyone, well tore my new block down (new to me) for rebuild got it in to the machine shop to mic, standard bore with a very small ridge in the top of the bore. Machinist says it’s ok will hone. This block 109 that I bought, well 2blocks came with a lot of parts, new stock pistons,comp cam,lifters,rebuilt heads, intake,new timing cover(trying to figure out make, some crap new turbo DNJ I believe, some crap 84-85 SS headers but lots of stock parts for a rebuild. Both cranks had to be turned 10/10 everything looks good though. My main question is bearings, heard a lot about TA 1557 cam bearings they sound good and then the main and rods, I’m looking at King bearings, sounds like these bearings really hold up well over Celvite or Federal Mogul, any thought. This will be a stock rebuild this time around with a few upgrades. I know this subject been discussed but I haven’t heard about the King? Also can we talk about crank end play and thrust bearing.
109 rebuild

As long as the bearing clearences are correct, any bearing will live just fine. Kings are good stuff as well as the others, it's a matter of personal preference. TA cam bearings are nice as well as durabond B13 , sealed power 1755m. Endplay is .003-.011 if it's larger than that there maybe and oversized thrust flange available. Crank will need to be machined for it though.
Thanks Tall Chinese Guy!

I would be looking at better pistons then better bearings. A decent set of forged pistons is a must on any rebuild I do . They will stand up to more abuse then the stock ones . Do some research on the bearings there is a set for a super charged 3800 park ave that are wider for the mains which are better then the stock narrow main bearings . Just my opinion on this btw doesn’t mean much lol

You are thinking of the king race bearings....
Reg king are softer but should be fine on a stock build

Thanks guys for the replies ! This is a stock rebuild pretty much except for the turbo i want and also the intake porting and throttle body boring. I'm only looking for maybe 400hp This is what i got so far for a list. Stock crank has been ground 10\10, block is standard bore, why bore it if not needed? I have heard stock pistons will go 9's?. All these parts I got for this build came in a package with two 109 blocks, stock heads rebuilt, gasket set Fel pro, Comp Cams flat tappet cam,springs and lifters all new, new stock turbo pistons, 18 stock rods, lower intake and more, more, more... Here's my list Please take a look any advice would be appreciated.

Stock pistons can survive somepower the problem comes when u have a hiccup in your tune at 9sec power level it can’t take punishment like a Fordged piston could . What are u going to tune with ? TT chip?
See my replies above
earlbrown- can you elaborate on that, your thinking I should bore to .010-.020 and new forged pistons? There is a very slight ridge at the top of the bore can barley feel it, the machinist thinks it will be fine?
That's because your machinist is used to being forced to go oversized in large increments. I can make you a set of .002 overs if that'll get rid of the dip there the top rings used to land. Or .003, or .004 or wherever the bore will clean up.
That's one of the cool things about my slugs, you don't have to pay for a bore job to clean up a bore. Just hone it clean and go from there. I can also move the piston up so if you're trying to get some quench and extra compression, you don't have to pay to deck the crap out of the block. Those two things alone practally pay for the slugs in machine shop savings.
