Would like my Z friends opinion on this. I really like the idea of having the power of a V-8 in my 79' 280ZX but I'm still not sure if it is a good move. The 2.8 that is in it is sluggish from the line (138,000 mi), and the top end isn't all that great. I would really like to buy fresh 2.8 and drop it in, but if I can't get the performance and power out of it that I wan't, maybe a V-8 is the solution. This is my first Z so I'm unfamiliar with a fresh Z's engine performance. The car is driven nearly daily and is in great shape, but just lacks the power I would like to see. Anyone have any good suggestions or alternatives on this?
