so I am about to order pistons for my build. its a ls2 stroker

4.00 dragonslayer crank
6.125 callies ultra h beam rods

now I am trying to debate between pistons

I originally bought a set of cp carillo pistons but it was a n/a design the first ringland was to close to the crown.

its between the
weisco k445x05 4.005 bore, 1.10 compression height, -15cc dish

or

diamond d1150 4.005 bore, 1.15 compression height -10cc or 19.2cc dish

the major differences I see is the compression height is one better then the other for a boosted motor? its going to see 18-20 lbs of boost f1c procharger.

the other difference is the 1.5 compared to 1.2 ring set. again is one better then another for boost?

and the wrist pin diamond uses 8420 and wiesco has the upgrade 9310 wrist pins.

which would you guys choose over the two?

I love my wise co pistons in my 3.903 bore 5.3 they seem so tough looking and it's nice when all your buddies are drooling over them. I hear diamond makes great pistons tho but I'm the type that when I get a good product I usually stay with them until something changes or they burn a bridge with me so just for ***** I vote wiseco they took boost and a super jacked tune or several and came out looking brand new

Taller the piston the better then
to try to reduce piston rock at bdc.

I am sure diamonds are fine also, but as far as experience I am running the identical short block combo you are talking about with those exact Wiseco pistons and its been working really well with no issues. Running about 20lbs of boost on it also.
Same block, crank, rods. and pistons. I went with what the builder suggested since they know what they are doing. The only difference is my pistons are gas ported.
