Is this a good system for a GM 4.3 V6 vortec with just short of 425 horse power. More upgrades soon msx out around 475 hp. Or what system is better.

Asked by: 97 Sonoma
This super sniper will more then support 425-475 HP. 22749 would also be a great match and will suppot up to 650 HP the primary difference is that the 22757 will support boost.
