The 2.56 will probably get swapped out next year if it doesn't work well with the 200-4r. The swap from the TH400 is happening when I put the engine back in next month.
1 thing leads to another, what started as a rebuild and trans swap now included a complete exhaust system, engine bay detailing, A/C system, etc...
Do you have a 2.56 POS?
