RE: Good buget forged pistons?
I've heard of the dome shaving, but I thought you were talking about taking a Dewalt and tearing it up in the garage or something....
Yeah, I reckon as long as it were balanced it would be alright....I just never really thought of doing crazy **** like that myself.
Thanks for the insight..

"Drilling little holes on the top of the piston"
This is something thats been done in NHRA Super?stock racing for 30+ years.
What you are doing is using a small amount of chamber pressure to increase the ring ring seal.
Wieght transfer in a piston? don't think so.........
The engine rotating assembly is balanced AFTER all the machine work is done. BTW, those holes are on the order of .024"
No matter what piston you use you may need to make some 'adjustments' to get the compression you want this can include milling heads, using thicker/thinner head gaskets, milling tops of pistons.
Also keep in mind what heads are being used as this can dictate what piston you can use.
My own piston list
Ross
SRP
Probe
Trick-Flow
The Speed-pro/TRW are very old in design. Dating back to the late 60's. Thats why they are heavy compared to the more modern designs..

sometimes I have a hard time expressing my knowledge to other that don't know much about engines
