Actually the Nova is fairly light with a curb weight of around 3200 lbs which is why so many were drag raced. The curb weight of my Z28 (automatic) was around 3400 lbs. No, the Nova didn't have a T56, it had a 700R4 build by Bowtie Overdrives. Everyone has their opinion on their favorite engines and I respect that. I'll stand by my opinion that the LS1 is superior to the best SBC ever made. There is a reason that GM spent all that money and now can make well over 400 HP with the LS series, power that only a BBC used to make. If they could have done that by tinkering with the SBC I suspect they would have gone that way.
