I pulled my head outta my a$$ for a few minutes and called Dynamic (for the first time in ??? years). Spoke w/ Sean and told him how the combo changed since the converter was spec'd originally. Asked him if they'd still recommend a 9.5" for my street/strip application and he said yes. Gave me some prices for having the old converter rebuilt & updated vs purchasing a new one outright... I'm thinking between the labor, bearing upgrades, stator, and whatever he said would be done, that buying a new converter outright may make more sense if/when that time comes.
