Anyone catch the new hot rod magazine? There is a nice 400M article, maybe that's not such a bad choice after all.
I love my 400 oinker! Got it in my 78 150 4x4. True dyno 390 plus horse, 450 torque! Smoke tires to the rims if you want! Sounds great and oil pressure 55-60 when hot Check out tmeyerinc for great way to build this "pig"
BIg block torque is the name of the game for 400M. It is the motor of choice for your Bronco rock climbers.
