    If your vehicle is an 01 or 02 model, you need to replace the flexplate, those years have thinner or lighter units than the 99 to 00.

    If you are indeed @ 440 RWHP, any of the stock flexplates should be replaced.

    Why not get the 9 inch rear axel so you can handle higher gear ratios like the 4.10?

    My Y3000 2.0 STR has a high effeciency rating of 98%, and I am getting 19 mpg. on the highway. Performance converters generally unlock when the brake is applied, and whenever you are out of lockup (i.e. below 43mph, stock tune) you WILL be burning more gasoline due to the slippage. The higher the stall, the more slippage, however the pros out weigh the cons.

    I do have a Yank 3000 and 3:73 with Stage 1X absolute heads, Z-06 cam, short headers and a dyno tune, making 347RWHP. The car gets 22 -23 miles per gallon on the I-40 going to the NC coast with speeds from 70 to 85 mph.
