The late '60's - early '70's were amazin for us gearheads.
Useda get a huge laugh readin Chilton manual's claims for HP.
426 Hemi rated at 425 hp at 4400 rpm .. f'rinstance.
It redlined at 7000rpm and pulled *hard* from 2500rpm on up.
Art Carr (if I remember) stuffed one into an early 60's Dart with an automatic
..would hold a few k rpm and just jam it into 'drive' to launch it.
One of the first 9 second street cars if I recall correctly when he got done with it.
Car Craft or someone ran an article on it.. engine was dyno'd out of the box from Mopar at 680hp, stock,
..only add-on being the dyno shop headers.
Dyno numbers are great for runnin a baseline before you start playin with your toy.
Long as you use the same one, same density altitude, etc ..you can tell what your latest mod actually does.
Always kinda tickles me a bit when someone drops a few hundred bucks
..then the dyno tells 'em they got an extra 10hp right at the redline ..-shakes head-
..just not very cost effective yanno?
I am all about huge gains where I use it the most, ie:
.. supercharging does it from idle all the way up, instantly, soon as you press the pedal.
-evil grin- .. people have said it's like bolting on 150 cubic inches
