318 REBUILD IN 67 BARRACUDA

Check out the cam kits on this page. I have used the SUM- K6901 with manual trans on 318. It ran good with stick heads and valvetrain There are plenty out there but these are budget friendly

IMO what you have to watch out for is getting to .500 lift with stock heads and springs. Im sure someone will chime in on this, but i ran that .444 cam with stock springs and no issues on the street not racing...I wouldn't know what it would do at max rpm LOL!
