[QUOTE="modo, post: 711739, member: 11716"] on a 347 i would go with afr 205s unless you need to worry about emmissions. start with a new block as well... i prefer the boss. don't worry about the rings let the machine shop worry about that as it really depends on the pistons you use and also if you really do put a blower on it in the future. 9.2:1 is the compression i would shoot for even with the blower as long as you don't run 20 or more lbs of boost @ 1600 or more cfm on pump gas. my motor is 8.8:1 with -26cc pistons and 56cc heads [/QUOTE]
