There are several 4.2l engines we are fixing to get wrapped up in a few weeks with some serious turbos cams, and some new and rare turbos and the combo should spool just s rad slower than factory but we have 22.5% more displacement and are able to open the exhaust valves way sooner on power stroke to spin that turbine wheel faster and sooner allowing all the air in LB/MIN to transfer to wheel HP/TQ and be a blast. There is seriously something incredible, intriguing, bad day deleting and just fun to rip your raptor around and have 750/750 on 37’s I’ll give her hell hard and not worry or break. Just saying, this is going to be fun soon. Lots
