i have a 306 with vitor jr intake, 650 speed demon carb,afr185 heads,1.6 roller rockers,comp cam XE274. i was wondering on how much horsepower and torque difference a 347 with this same setup would make. i am gonna be bolting this setup on and am just wondering how much the horsepower and torque numbers would change. thanks

you would probably notice a big increase in torque and hp with the 347. especially with the afr 185's, they will flow nice with the 347. but if your gonna use it as a daily driver, be careful who you get the 347 from, a lot of them are known to burn oil. try and stick with a reputable company like coast high performance (coasthigh.com). also, unless your already set on the 347, i would consider the 331. its much more reliable for a daily driver.
