go 20 over with those pistions come with rings and you can find cheaper pistons on ebay but i was using those before and they are good.

Bearings you can get clevite 77 rod and main or ACL racing series almost same price from ebay also if you crankshaft is bad you need to undersize it so find out what candition your crank is first. before buyin any bearings.

I paid 1000 for an already assembled .020 over weisco, crower setup with 0 miles. Sometimes the deals are out there and saves lots of time.

So should i go another .20 over? or just .10 more over to make it .20 over. i found a kit on ebay for $114

What you guys think?

 

[boosted_ego6985]

I would just go another .10 to make it .20 over. those kits are easy to find on ebay for cheap and not to mention that the more your bore the motor the weaker the cylinder walls are. I at one time had found some npr pistons and rings together on ebay for around 80 bucks with free shipping and that was from a store not individual. Stores name is domesticgaskets on ebay. I don't see it being much cheaper then that. Good luck

.010 thats odd how did you come up with this?

you sure its not a std bore with excessive wear?

 

[MotoEclipse]

.10 meaning just 10 over. it was documented by the previous owner its been bored 10 over.

 

[RamenPride]

.10 meaning just 10 over. it was documented by the previous owner its been bored 10 over.

do they even make .010 oversized pistons? That would be like .2 of a mm.... I've only ever heard of .020 and .040

 

[BogusSVO]

if it was bored over .010 that would be custom rings and pistons....

and tring to machine a block .010, geesh that would be a pain, even if you just had .002 wear, and leave .003 to final hone hot.. that gives you .005 to bore and that would be .0025 from any 2 points 180* apart

pull it apart and have the block mic'ed.. that will tell the true story...

 

[MotoEclipse]

Yeah im ganna get it mic'ed for sure. im just tellin everyone what i know about the car. and what the owner told me.

This block is kind of a mess honestly ..

ill post a video of the pistons soon in the cylinders.

Just thought I'd toss this in for consideration. Top Line pistons do NOT produce the same compression ratios as the pistons they mimic. So while they may be cheaper in price, there's a reason for it.

Sorry im meaning .010 over.

that a big gap damn !!!! WTF

 

[MotoEclipse]

So think the owner is lying about .010 over?

I mic'ed it to get an estimate. i got 3.5 inches. so it has been bored out .020 over

 

[BogusSVO]

Not the first time an engine was built and then had the std pistons installed... I have seen it several times over the years..

get it pulled apart and have it Mic'ed, you may be lucky and get a hone and install some proper sized pistons.

 

[MotoEclipse]

I really hope so. cylinder #1 has 2 scratches in it. they are worrying me. i dont think there going to be about to hone them out.

 

[Ghostcrafter]

Tore down my engine today, discovered the same thing in mine. Except I also have a cracked head, the block has a scored Cylinder 2, and it has a chunk missing as well. Oh, and a melted piston in Cylinder 2 as well.

I need a new block...
