I am rebuild the 305 in my 92 B4C and wanted to know what you all think about 2 cams I am looking at.
First the motor is getting bored out .030, pocket porting the heads and gasket matching the intake. It has headers and cat back on it and I can burn my own chips. It’s a 5-speed car with 3.42 gears in the rear end.

The 2 cams I am thinking about getting are both from comp

Cam 1 XR258HR
206…212…480…487…110

Cam 2 XR262HR
212…218…487…495…110

The car will have to pass emission testing, I am thinking that cam 2 may be a little big. The car will be my everyday diver for about a year so it needs to get good gas mileage.

So what do you think, anybody running either cam?
Thanks guys

 

Or should I go with 112 centerlines on the cam?

 

The first will act like stock, not too much different besides a 1.6 rocker swap except thats more lift than you'd get from doing that. The second will idle and run fine, I've run a 212 intake duration cam on a 305 and it idled and ran quite well.

Use a 112LSA. Your computer will thank you.

 

See sig for the cam I'm using.BTW it's a custom grind.

Thanks guys.

I think I will go with comp's XR264HR with 112 centerline.

 

LOL
I learned that a long time ago.
