454 vortech power and torque numbers and AFR

[John Cunningham]

School Bus, Medium duty truck, Generator or Industrial applications. They are starting to show up used now.

I read it..........basically a 540 engine that I built for my hot rod....That torque number is easy but just not that low....stump puller like a diesel all day long!
That was a cool read
Thanks

So are you going to tune and give it another try with the 0411 then? I am curious what the difference will be.
