what is the best way to change a tranny mount with out pulling the tranny. and is there a big difference going from 273 or 308 to 343 gears? for a cam that kicks in a 2200 in a 75 chevy pickup

Put a jack under your tranny and chage the tranny mount. Huge difference from going 308 to 343. 343 are a good cruising gear.

There are a lot of perimeters to be considered. What transmission, tire height, and objective. Offer more details and we can answer more precisely.
