The major difference between the power glide and the st300 transmission is that the st300 has an extra gear giving you better acceleration. However, based on their gear ratios the top end gear ratio for both transmission is 1. 0 and therefore does not have a top end advantage over the power glide transmission.
The st300 is a two speed like the PG however some have a variabe pitch torque converter and most have a chevy and bop bellhousing. add a comment
