My first 455 using my SR 614 RAIV heads flat valves cleaned up a little in the pocket(all the rules allowed that year in NMCA), 72 SR-HO intake, SR 73 SD Q jet ,Ultradyne HFT 288/296 on a 108 LS through Hookers into mufflers on the dyno was about the same HP rpmed a little higher for peak. Ran 117mph in a 3950 lb TA with stiff road race suspension and 3.42s. Great street, autocross and drag combo. Even ran A/C!
I think those are "real" numbers that will hold up using wt/mph calculations. Higher dyno numbers will not match track numbers. Some dynos are "generous" and won't run the numbers.
