4.10 or 4.30's????

[Rick 91GT]

I agree your 347 would greatly benefit from a good breathing intake. I am currently running 26" tall tires and 3:73's I shift at 6200. I hope to get into the 11's as it sits but I am going to 4:30's and a 28" tall tire which will better fit my Anderson cam. With the 4:30's and 28" tall tire I will go through the traps around 6300rpms.

Hows the suspenison on your car? If it doesn't hook with the 3:73's the 4:30's are even going to make it worse, why not get the power you have to the ground first. Whats it run now? Did you get your cooling issues fixed?
