What kind of pistons are these?

[JerryDaugherty]

Also I have these pistons in and I cant find anything on them with the numbes stamped into it. They were claimed to be forged Speed Pro. Any help is appreciated. Are they forged, what compression, and the make. Also will they handle a load, like 10lbs boost or 100 shot?

My forged Speedpros didnt look anything like that, those have huge eyebrows in them compared to mine, so looks like you could run a pretty big cam with them, your best bet is to pull them out and get more pictures.

they are cast sealed power pistons.


they can take a 100 shot, or 10lbs no sweat, just tune it right.
