Re: Thoughts on the stock 402?
The biggest drawback on them is they are not a very efficient engine. Flat out use more fuel. I had a 68 396 SS Chevelle at the same time I had a 69 GTO. Both were T400 auto cars with comparable miles and mostly stock (headers). The GTO would get 16 to 17 mpg and the Chevelle was 11-12 mpg highway.
