Default Re: 7 " vs 8 " converter?

I would tend to agree with Mark as to the 8" being faster in this particular combo. From what Danny's saying in regards to the small engine needing to be in it's torque range quickly, because of the amount of torque and where it is,the 7'' gets it there quick enough, but is not turning enough RPM to sustain lockup in the 7". A lightweight 8" piece, loose enough to get it to approx. 3-400 over peak torque ,as the PG is a little more conv. sensitive even with a 2.02 and needs a bit more to leave. Gear selection is important also as the 8" will couple better in high because it has more fluid capacity, you should be able to get away with a little more gear. With the right 8" piece and corresponding gear it should help on the leave, on the fall back which is critical on the PG and keep it locked up fairly well in high gear. After all is said and done, your combo will run it's best where the engine is operating at it's happiest, and every one is different. Hopefully this will help out a little.
