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.

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
