I have a 565 bbc 3600 lb car. Motor made [email protected] rpm and 744ft tq @5800.
I have a new 8in converter that was made to stall at 6000. Took the car out last week and on the trans brake the car revs to 6500. I launch it shift it at 7300 it falls back to 6800 3sp trans. Never falls below 6800. Only using 500 rpm each gear can this cause me et loss?


I put a Restrictor plate on it to run the 9.90 index and on the brake it stalls to 6100 and after 7300 shift it falls to 6500. I only picked up 3 mph going from 9.87 on Restrictor to 9.50 on motor 60s and 330 was better with the restrictors in. Is the converter to loose?
