A friend of mine used Hyperutectic pistons in a BB chevy race engine reving to about 6,800 rpm then one decided to turn itself into gravel!"Never again" i think he said or words to that effect.

In any situation where you don't have to use them , then don't !! If your limited by budget , or rules(claim) , then just understand that they will eventually break like marty described ! With the price of forged pistons getting more economical for the average racer , I'd definitely spend the extra money on them ! So my opinion is ....... they do not belong in any race engine that does not have a claim rule , because they will break at some point , and ruin your engine ! For the extra $200.00 or so , I'd rather know that I can trust my pistons to live for a long time .

hey sdhnc29, so no hypers either if its in the budget for forged. Whats a good priced forged that you have had luck with. for a hobby stock 3000 - 3100 LBS.

If it's in the budget , definitely go with the forged ! For the money , you would be hard pressed to beat the SRP pistons . Your looking at $452.00 for any shelf stock flat top for any bore/stroke combo , and they include pins , locks and ring spacers when needed . Considering that your looking between $175.00 - $250.00 for a set of Hypers (depending on your comb) , the forged are a minimal investment for the durability that you gain . We use the SRP in any engine where a guy is limited on funds to spend , usually in hobby stock or street stock classes . We have never had a piston failure in any engine that we have used them in .

I've bought cast pistons thru Midwest Motorsports for a couple years now. The Cheapest kit they have and I am very pleased. No problems here. The brand is "Dynagear" and they go up to 13.5 to 1. $100.00

because you asked about cast pistons i,m guessing your on a tight budget or a claimer class. i would go to speed pro hyp. they cost about $20 more for a flat top 350 than cast but they are lighter and less than $100.

Not all people run cast or hypers because of money or claim. We are stuck with a no forged and no domed pistons (if you follow the rules). Does running cast vs. hypers cost you much performance or durability at 5600 max rpm. Durability is very important ,but I am also on a pretty tight budget.
