454 to 700r flexplate
 

swapping my 305 with a 454 got all my parts lined up for the swap but the flex plate bolt pattern is different. Does anyone know a part number for a "part store" 454 flex plate with dual bolt pattern? yes I know it might be hard to come by since the 700 never came behind a 454 but I'm sure someone here has run into this.

I know I can order a B&M and other aftermarket but I was hoping to get this done over the weekend and dont want to wait on shipping. Thanks

Most aftermarket flexplate are multi pattern. Depending on your 454 vintage the most common store part numbers are below:

Pioneer part numbers #
1970-75 FRA111 (mix of pass cars and trucks applications)
1974-90 FRA141
1991-00 FRA321

700R4 torque converter will use THM350 mounting points.
