I want to see what the air/fuel ratio is for my 88 302. I have no cats so I dont have O2 sensors. Whats the best and easyest way to get the air to fuel ratio. Also I have a vortec blower, and want to know if mass air sensor would help alot or if it wouldnt really do much. Another thing I want to get ride of my AC compresor and put a smaller pully on my blower, any sugestions and belt size? Thanks alot for the help.

 

Will any one help, PLease!!!!

 

so your running rich? or not rich enough? also look into those altinators that have a small pully and dont make much power , for drag cars with no stero and power windows and such.

 

If you want your A/F ratio and don't have O2 sensors you will have to get the car on a dyno... What injectos are in the car? Is the mass air calibrated for them? You don't get any gains from just a mass air meter... You can order smaller pullies for the blower, but that's a seperate belt form the serpintine belt that operates your accesories... You will have to measure all of the pullies to get your belt size... Good luck

 

I have the stock 19 lbl injectors, but want to get 30 lbl. My car only has one belt, but whats the easyest way to messure, with a string.
