I just got a 78 Bronco with a 351M. It has Hedman Hedders, Dynomax dual exhaust, Edelbrock Performer intake, a Holley 4160 4BBL carb(Part #: 0-1850C), and a new cam...but I'm not sure of the specs on the cam. Can someone give me a ballpark in HP/TQ without cam specs or just without the cam period?

From what I remember the stock 351M in that year was around 175 hp and the 400M was around 190hp.
THe factory 2 bbl was a gas hog and the factory intake was very restrictive as was the single exhaust. I would think it would be very fair to say that you would have up'ed the stock HP from 175 to around 210 hp. THat would be my guess without the cam.
Drop in a 400M crank and a set of boss heads and that thing will scream witht he right cam.
