Back in the IHRA days I had a customer that ran a Crate 385 in a Malibu wagon. The 7.5 would last about 50-70 runs and spit out the pinion or take teeth off the ring gear. That was with a good spool, caps and axels. Went to the 8.5 and the ring and pinion problems stopped. As a by product he was able to get better brakes on it, too.
