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.

Right that's why the +40hp/+40trq gain I mentioned from the Headers and intake was AFTER they already fixed the carb issues with a new Edlebrock 800.

I graphed the difference & the gains are through out the ENTIRE curve not just peak.
New Stock(new 800cfm) vs 340(Carb +Headers+Intake)

lol,,no cam yet and for damn sure no new aluminum heads.
