See if it's a cracked piston or just a ring.
I will, but I will likely do it last, rather than first. I have 3 or 4 blocks,and enough parts to put together 3, 383's and 1 406 (in the garage currently). The motor in the car now has cast (hyper's) pistons, so I suspect the piston is not broken. They explode like the rear window of a car when they break. I am guessing that I find a not so good hone job when it comes apart. It has never been "right" from day 1.
You were spraying Hyper pistons????
Only for about 15 years or so. They hold up well as long as they don't go lean. I have not sprayed the hurt 383 in the car now. In the old days, finding a reasonably priced forged piston for a 383 with 58cc heads was not possible. In the mid 90's, the aftermarket was so limited that a custom forged piston was the only option. In the late 90's SRP and others had $500-$600 piston sets, but hypers were selling for $115 a set. Because I have been lucky with them, I continued to use them. If I step up the power package, I may finally break down and buy a good piston.
