Factory 68-71 340 puts 325HP on GM Dyno

I dont see the stock 302 whoopin' the 340 either wild. It seemed a littly hyped up to me.....

But the hey lasted longer than the newer chubbies until the roller ones too, I think......

Seen many ABUSED 283 power two ton trucks with the same little 283 they had since new running WOT 90% of it's life when I was a kid.


Never was interested who they got so poopooee in the later years, just wondered why they did it.
