I can sympathize with the letter. I bought a white 1974 SD455 4-spd in the mid-1980s. The engine was apart because the owner was experiencing a rear main oil seal leak. I put the engine back together using the mildest SD455 camshaft that H-O Specialties sold. The cam was close to Ram IV specs without the 1.65 rockers. After a proper break-in period, I took it for a run down a 1/8 mile track. About 3/4 of the way down the track, it began sputtering, probably due to a fuel delivery issue. I talked to someone (Ken Crocie or Nunzi) and they told me the fuel bowl was too small in the Q-jet and I needed to add a pusher pump or switch to a Holley. I never modified it, but it was never intended to be a street racer or street/strip car.
