an amazing amount of work done on that engine but really my 360 426 at 1/4 the cost is just about eqiual maybe 20 hp and 20 ftlbs less . the poly looks tn times better with that intake and headers .
I'd be curious to see if any of these magazine builds are run at the track to see if the mph confirms the engine dyno number.
Some are but not many, don't get why a formula found on the web is considered more accurate than a dyno ?
Does anyone know how they came up with those formulas in the 1st place and wouldn't they had to use dyno to check the accuracy anyways ?
I wasn't even referring to the formulas. I was just thinking in terms of common sense. There seems to be a lot of "dyno'd" 400 hp engines out there running mid 13's at 102 mph. That just doesn't pass the straight face test. You kinda have to take magazine dyno numbers with a grain of salt and understand their intent and associated inherent bias.
I do enjoy the parts comparisons though. IMO, that's one of the great advantages of a dyno - minimizing variables, testing specific parts against each other, and maximizing the tune of a specific combo.
decent power, anything north of 250 hp is $$$$those slant sixes were reliable and ran forever , to bad they were ignored in North America they can make some decent power
