Hi guys, I am building a 427 SBC and am aiming for around 550 HP. Do you think the stock rad with a Be Cool Qualifier Dual 11" Fan and shroud will keep this motor cool? Fans Pull approx 2780 CFM I was going to purchase this fan with a Be Cool Direct Fit OE Rad Part #15010, but thought it would be worth a try using the original before spending $650 US on the Be Cool Rad. Be Cool says that Rad and Fan will cool 700HP. Thanks!
