MPG Estimate
I'm lookin for my first car and i have my eye on an '87 IROC and its perfect. The only problem though is it has an aftermarket 4 barrell carb, and im not lookin to race it or anything. Just wanna street car. So its an 87 IROC with a 305-V4 (V4? 4V? i dont know what its called) and i was just wanting to know what kinda gas milage ill be lookin at with this beast? If the gas is gonna be outrageous, how much to put a 2 barrell carb in there? Thanks in advance!

So about what speed will all 4 kick in? or is it different depending on which carb youre workin with? Also, overall, would it be even worth the trouble with this car if i just want to run it as a regular car (no racing)?

It's not about mph to get teh secondaries to kick in, it's gas petal. mash the gas past a certain point, the secondaries kick in.
Gas milage on a carbed 87 Iroc? My guess, 15mpg if you are luckey.

It all depends on the carb man, all I can say is if it has manual secondaries, keep ur foot out of it if you want good mileage.

Thanks guys you all are being very helpful. So I wanna see a vacuum carb in this thing if i hope for decent mileage? From the way the guy sounds i highly doubt he would know what kind it is. Is there a big distinction between a manual and vacuum carb so i can see( or have the guy see) what kind it is? Its about 60 miles away so i cant exactly walk up the road and shoot the breeze with the dude.
