I have an 85 carbd 305 and no longer have to take emisions tests for my state. what are some parts i can take off that are used for emissions that can be removed to add power?
thanks guys

 

All of it including the catalytic converter. All you need is a pre80's carb and electronic dizzy with vacuum operated advance.

 

Only removal of the cat will give you any extra horsepower & only if that is an older design & not free flowing.

A new Hi-flow cat, like my Magnaflow, only costs you like 1-3hp. Not enough worth messing with taking it off.

And technically, despite not having to be tested....Emissions are a FEDERAL requirement to have. Even if a state doesn't do emissions testing, it is still technically illegal to tamper with emissions parts by removing them.

Yes you can probably take them off & nobody will say anything, but that doesn't make it legal.

 

Why would you do that? The computer controlled carb has way better drivability than any standard carb. Power cant be found by ripping things off the car.

 

I don't pretend to know why, but I grew up with pre80's muscle cars and drivablitiy had very low priority for most of us except those who had to the money for it.
I don't own any pre80 cars now, but I sure would like to, they're simple, uncomplicated, and fun to drive. Maintenance intensive, I agree, but well worh it, difficult for others to understand, but there's nothing I can do about that.

 

Does the Magna Flow still do a good enough job on the emissions?

 

You tell me....

At 170,000 miles & a 2month old Magnaflow cat, my test results were:

High Speed-2692rpm
HC 220-allowed my reading-4
CO% 1.20-allowed my reading-0

Idle
HC 220-allowed my reading-16
CO% 1.20-allowed my reading-0.01

 

Very nice, thank you. I believe mine needs to be replaced before next inspection in a month so the timing of your post was perfect.
