Guru,
Hey man that is looking real sweet. I can just imagine how it must haul ass with that motor and tranny combo. Looks like a great fun car to drive. I also am liking those sail panel windows, might have to get a set for my 85GT.... Good luck on the trip. Sadly I am not gonna make it up there the fiero just needs too much work and I am still trying to get things reliable on it. Peace
Pete

I went and had the wheel balanced again. When I installed the 13" rotors and lateral link brackets, I had to remove some of the wheel weights.
I am scheduled for the chassis dyno on Saturday morning and 7K rpm in 4th will have the rear wheels spinning at about 150 mph. I figured it would be a good idea to get them balanced again before getting strapped to the dyno!
When I dyno'd the SBC/Getrag car, I stopped around 6200 rpm, so it only saw about 135 mph.
It would be great if this car has 100 hp more than my SBC/getrag, which would be 382 whp, but I will be happy with anything over 350 whp.[This message has been edited by fieroguru (edited 07-04-2013).]

Guru,
Hey man glad to hear you are getting ready to dyno tune that baby. Good luck with it. I sincerely hope it turns out to be everything you hoped it would be. If you ever drive that bad boy down into TN my neck of the woods gimme a shout I'd love to see it in person. Peace
Pete

Damn that's nice man! Very nice for stock heads/internals (excluding cam, which can play a big part in power).
I hope you're able to get the D.O.D. working, your MPG is going to be really nice then.
