Right now I am running a THM 350 and the mpg is highway. I think you could run a 650 Holley with no problem except a loss of some power in the higher rpm range. It seems mine breathes quite well with the 700 but I am considering a 750 and a 100-125 shot of NOS.

 

oh that was highway..ouch! lol what do you think you get for city mpg? well its ok if i lose some higher rpm power since i wont be racing with it yet..wow NOS would be sweet! so i take it you race yours?

i wonder how much mpg it would add when i get my 700r4 tranny?

 

Like I said, I do not drive it "nice". Mpg around town I have no idea, when the gauge says low I fill it.

I do not call it racing, I prefer "trolling for horse meat"!

 

hmm i wonder how much i would get if i drove it nice? cuz i will drive it nice for the most part but will burn some tires sometimes too

lol well with the NOS you will def kick some horse a$$ lol

do you know what your best 1/4 mi time is?
