Rocky and I have known about this car since Steve bought it from it's original owner (who was also from Nebraska) back in the 80's, so we knew just what condition it was in. Now I've got no choice but to remain neutral in all these Super Duty vs. 455 HO discussions on the 70-73 Firebird forum.

Jim,
You did good. Real good! It is a very nice TA and in very capable hands. I think you should haul it over to the TA Nats in late August (hint, hint). As for the SD vs HO dyno wars, Dan and I have seen a slight nod go in favor of the SD motor due to better breathing heads and the 301/313 cam when compression was equal at 9.25:1 or above. When the compression is lower (below 9.0:1) they are very comparable in regards to hp and torque. Remember, they both ran E/SA back in the day in the F body. The HO gets to maximize its compression up to 10.19:1 vs only 9.55:1 for the SD in NHRA stock class and that does make a big difference.
