Here are the best so far among all race engine builders. A 432 Cannondalechick(red) vrs a 450 UPSMan(green) vrs a 460 Wistech(blue)

Ill have to do some digging to find some more files. Tim said he may have a better dyno chart for a 432.

Here you go.Its hard to do a decent comparison since your tach signal isnt showing up.Can only go by speed.Gearing affects that obviously.HP is same though either way.Not bad for no porting,stock airbox with used filter,and a quiet core pipe.Best AFR of bunch also!Thank you.[attachment=3814:Stock_Cr...Showdown.jpg]

Yep thats pretty much worthless without a tach signal. Otherwise going by speed the gearing and tires size would have to exactly the same size as all the rest to compare the lines. The max hp number is about all that can be compared.
You have to admit that is an amazing number for a 450 with a stock head and just the intake and cam mods. Thats around 10 more than the other atk and stock dales on this dyno.
