I guess I'll leave it in. Don't really want hard shifts nor care about chirping the tires but does leaving it in defeat the purpose of using this particular valve body? Would I be better off just leaving the factory valve body in the trans.? Engine is a 400/470 stroker.
You are still getting the benefits of the valvebody so I would swap it. It's not a big deal, to me anyway , to drop[ the pan and valvebody so maybe run it without the spring and add the blocker and if it's too harsh take out the blocker and put in the spring ? If you have a pan with a draain plug using a clean catch pan you can recyle the drained fluid.
And for god's sake don't put that ATF+4 shift in the trans.
