98" Pistons?

98" Pistons?
Who is the recommended brand for 98" pistons?
I'm thinking about having my stock cylinders bored out to 98" and putting in a good pair of pistons.......is Wiseco the preferred brand?
I have 30000 on my 95" pistons, I'm going to do a CCP test on it over the winter and if it's down or leaking..............then 98" it is.

I'd maybe call Big Boyz and ask them.
The pistons come in a range of compression ratios and they'd be best to tell you which to use.
That's my opinion.
Wiseco's are good, though!
One other thing, just because your compression is down doesn't mean it's the pistons/rings.
Leaking valve seals or valves that aren't sealing can bring it down, too.

Steve - I think you can get 3.9375 pistons from Baisley iirc. Obviously you would want to send them your cylinders so they can be fit to the pistons.
If your using the same heads and increasing the discplacement your ccp is going to increase. Possibly beyond the useable range of your cams. You're going to need to figure out what kind of dish is needed in order to keep your ccp in check.
I'm sure you have thought of all this, but thought I would throw it out there in case it helps someone reading this later.

Steve, you must be looking for a project because 30K isn't much on the engine; unless you need a "reason" for your spouse to do more engine work. Wouldn't be the first time a confirmed tinkerer/builder "needed" to do more engine work.
Why not put the $$$ aside for a stroker crank and build a 103/107?
Head-Quarters uses CP pistons so I'm sure you wouldn't go wrong using them.

I would love to do a new crank and go that route...........but no money equals cheap upgrades.
I've already gone thru the calculators comparing what I'm at now and what I would be at after..........and things look good.
Not sure what or if I'm going to do...........just doing some early research now.
I looked on Wiseco's website and didn't see anything for 98" pistons, so I guess CP would get the nod.
