If you could, I would install the 200R4.
Better gearing,gear spacing.
700R4 has bad gear spacing.
200R4 has taller overdrive gearing.
A nonlockup converter is used in the same trans,it just will not lock-up & give you the better gas milage as a lock up converter would..
200R4's came in Buick Grand nationals, V-8 Chevy's,Pontiacs,lots of cars,etc, just make sure you get one w/the Chevy bolt pattern.
They are good tranny's, many Buick GN guys put a lot of abuse to them w/a turbo.
Normally aspirated inline Chevy, no problem!!
What rear axle gear ratio do you have?
