The 428HO is scheduled for the dyno this Tuesday! The cam has been broken in on the test stand and now we'll find out how much power the pure stock motor makes...Dan dynoed another stock 428 HO (69) a couple months ago with a 068 cam as well, but with 10.2 to 1 compression and it made 415 hp and 495 tq...so, were hoping for 425 hp and 510 lb.ft. Dan is going to dyno it with the RA exhaust manifolds rather than the long branches, so will give up a few hp and tq.
