I would need to have a couple head pipes made to fit the dyno but that's no big deal. Point ignition, would only take a couple hours to have ready to run. It would be interesting to see what it makes for stock power. My guess would be around 310-315 HP 430-440 ft. lbs. peak torque. I will try to make it happen.

The ‘71-‘72 455 HO engines with a smaller 068 cam and heads that aren’t as refined as the 455 SD heads were rated at 335 and 300 hp respectively, surely they were making around 350.
I would bet the terribly underrated ‘73-‘74 455 SD engines rated at 310 and 290 hp are actually making 350 to 370 hp. The cam they used is the same profile as the 744 cam, and still they were under-cammed but still less so compared to the 455 HO. We shall see.
Such a nice car, finding one in this condition is a once in a lifetime score.
Thanks for sharing your build with the PY community.
