How about a good Drag race 904 build discussion
I have a saying. Pick your part, pay your money.
Based on some of your comments, you don't have a clear understanding of the failures, causes and things to look out for. All of them are primarily 727 issues.
Some people spend money on stuff that will provide ZERO benefit. Do I care, nope. If you have budget constraints, the money you spent on that high dollar sprag ~$350 and drum ~$600, could have been better spent on a quality converter. Just don't complain when someone with a "junk" parts 904 and great converter kick your tail for under $800-900, less than your two parts alone. A lower cost alternative that sprag is a low band apply valve body.
People will sell you whatever they think they can a lot of times. Are the parts better, yes. Are they necessary... HELL NO. Some will buy the "trick" of the week. you can roll that high dollar piece too. You don't like the answer you got, have at it. I think you wasted money.
Some of the heavy cars I know that run 904/brakes with all stock drum/sprags
10.52 128 3350#
10.38 130 3400#
10.65 126 3400#
Then there are Tony's cars coming in at 2850-3200 or so.
Like I said this isn't a discussion, you already made choices regarding parts you THINK will benefit you and you are looking for a pat on the back to say you did good. I know that two of us in here aren't going to do that.
Build your stuff and run it.
