My old man picked up a 73 Mach 1 with a 351 Cleveland. We have no idea if it’s the original motor or what really has been done to it. Here are the details I can confirm.
-650 cfm Holley DP with no mechanical secondaries or choke.
-Performer intake
-full msd ignition (not sure if part numbers)
-comp cam hydraulic roller
270 duration intake and exhaust
224 duration at .050
.519 lift
-heads appear to be factory but don’t know what size valves or if they had any work.
-1 3/4 hooker headers
I know without the info on the heads this is really a shot in the dark but what would be a good HP and TQ estimate.
