I think you will find that the Eagle SIR rod will be less expensive than have your stock rods reworked. They come with ARP cap screws and are set up for floating pins. Plus they are matched for weight which will make balancing the rotating assembly easier.If your goal is mid range and driveability I wouldn't go any bigger that 750 cfm on the carb. I have a 360 which makes approx 370 HP and have been swapping between a 600, 725 and 750 carb and keep going back to the 600 because of the throttle reponse and driveability.
