I've been going back and forth with this and could use some experienced opinions.I'm trying to decide between 180 and 200cc runner sizes,64cc chambers.They'll be going on a 355 4 bolt,flat top hypers,.488 lift cam.I realize I'll have the nice torque with the 180s but I don't want to short-change the motor if I decide to step up the cam.On the other hand,I don't want to deflate the motor because of too big a runner.The 180s make more sense but I figured I'd run it by all the knowledge on the board,nice option to have.Anyway,I pick up the block tomorrow(Christmas in November)so any input would be great.Oh,it's going in a '67,mostly street,some strip.Thanks guys, Tony
