Funny thing is that the pentistar block has Siamese cylinders which is frequently utilized on engines that are or planed to be boosted at some point which i do believe the pentistar was at one point. Heck at 8lbs aftermarket i think it turns out decent gains with 100hp at the crank thats nothing...
Can you tell me what condition the jeep was in? News flash to everyone, putting a 35-40” tire on a dyno gives false readings. Imo all reading should be taken with stock gearing and stock tires for apples to apples. Not 38” tires on beadlocks regeared to 5.33.
