I have a 76 monte with a 305 2bbl, 19000 miles, Too young of a motor to pull out. I live where theres a lot of hills. I want to change the dome and carb. The cam in the car is a 176-194 duration, 350-385 lift -18,14 intake 28,-14 exhaust with a 109 lsa. The only thing I understand is intake valve closeing and beeing at 14 degrees to aid in low compression cylinder pressure. All of the cams I've seen for the wimpy 305 heve 25 to 28 degree intake closeing. Can someone help here, I seem to see that those cams would lower my cylinder pressure
