Extra hp out of my 340.

Yes. That's the more recent magazine tests I was thinking of.
Note that the first jump in power came from installing a carb that wasn't "stuck" with whatever calibrations it had.

I think general lessons from these two magazine tests are valid, even if taking the absolute numbers with a couple grains of salt.

Yes but also the whole package as it came together! While the bigger carb let’s it breath, which all MoPars suffer from in stock configuration, the intake (RPM) in test 4 is about what most people can expect from just bolt on parts (not to shabby IMO) the additional HP with the cam is really cool since it is still a small streetable Hyd grind that won’t hit you in the backside on around the block egg and milk runs.
All together a 43 hp gain with a 28 ft. lbs. gain in torque at peak. And it’s a gain from bottom to top. No loss.

And we (they) didn’t get to porting or swapping heads yet.

Hummmmmmmm..........
