Stock 340 dyno tests?
The 340 did come with a pretty mild cam I wouldn't be shocked if it was 275 hp especially with stock tune, but I think it was slightly underrated, probably more like 300 hp. The 245 hp was net add a bit more for cr and better head flow so say more like 265 hp net for the 275 hp doudt only loss 10 ish hp gross to net. Really don't matter was a great package that responds well to mods.
