I was pretty upset when I ordered some and opened the box also. I really don't understand why they stopped making the other pistons
Me too,and I feel confused because My cams and cylinder head need really good compression and those
Pistons doesn't look like to do the job! But the compression is the same or different on both pistons? Is the same dome 8.25??? Any experience?
We use 4 piston , a big selling point is the communication Luke and Josh offer. We understand these companies get backed up and a head could take over a month to get back, we just need constant communication so we can always keep our customers in the loop. They also have great customer service and aren't in a rush just to get you off the phone.
I purchased the Same 8.25+cc pistons and was concerned as well. Ive been using the Pointed dome or the Import Builder spec pistons for the past 8 years. According to Wiseco these are the new higher flowing design and they made more power i guess due to restriction issues. All i know is i hope they work like the old ones cause i made over 500 with nitrous. Hopefully the change was for the better

The pistons? I'll be assembling the engine this week and hopefully on the dyno next week as long as the fuel comes in. Ordered from a different place and it's taking forever to come in.
