Some people have told me going from a 3.1 rs with t-tops and putting a 350 in it will twist the t-tops. is that true. and also would my v6 have been faster than a 305 because ive also heard talk about that.

In general, all 3rd gens need subframe connectors to help reduce body twist, T-tops or not.

It is possible for a particular V6 to have more power than some 305's. However, do the same things and spend the same amount of money on a V6 and a 305, and the 305 will be faster. Every time.
