Dogdays makes lots of good points. These days the speed pro's are so costly as well as being made overseas so you have to really consider if they're worth it. The TRW's used to be nice forged, inexpensive pistons.
They were strong but heavy, same weight as the cast pistons they replaced.
A lot of guys like to comment on the weight of the old TRW's but the reality is they were about the same weight as the stock pistons they replaced. There are still guys running old school stock stroke 440 combos with the TRW's running the 11's.
