Had my dyno sheet re-scaled from my last post as suggested, how does this look now ? any input would be appreciated

 

Here, I hosted your image for you.

 

It's good power that thing has got to be scary fast to drive.

But, I'd expect more power from your mods. What do you think is causing the tq drop off after 5K? My LT1 put down 414whp on a Mustang Dyno, you should be more than 15hp up on me I'd think.


355 LTY1 LE2 heads 230/238 .565/.565 110+6 full bolt ons 6 speed.

Do you have the AFR of than run?

 

More input please

 

Sorry hrcslam didnt see your question about AFR the first time I read your post, AFR was 12.8

 

429rwhp through a 12 bolt aint too shabby honestly. I would've expected a little more (10-20) with your set up. But dyno's aren't an accurate way of measuring actual horsepower. AFR looks good too.

Take it to the track and let us know how it does. That will tell you how it really does.
