The 4.3L in my Blazer will turn over the 32x11.50's with little trouble. lol

Now if I could just stop breaking motor mounts.

 

nope K&N cai only, didnt know about the tb blade mod, i found this site about 3-4 months before i quit driving it, its for sale

 

If you still got it go do it, that way when someone test drives it they wont think its gutless.

Oh yea, I also had March under drive pullies on the 4.3.

 

what do you do to it

 

take the 2 screws out of the tb blade and remove them, then open the tb and you will be able to pull the blade out from the top. Once its out, take a dremel or grinder or something and cut the half moon piece off, but DO NOT remove the whole metal piece because you can see the idle air hole in it is sized for the 4.3L. Once the half moon is off smooth out the edge and reinstall it. You will be amazed at the difference in throttle responce.

 

i may do that if i dont sell it soon
