Pistons for B&M 144 Setup???

30% stroner than what?

Are the 243's a Hyper piston? I wouldn't use them in that app. unless the PSI is low. 5-7 psi is good. A forged slug would be great and have the abilty to take on more PSI. You could really turn it up then without fear of shattering a slug.

Anytime you see the word "recommended" You should practicaly mentally change it to "Mandotory" unless you really know what your doing. It's a safe than sorry thing.
