I went to have my car put on a chassis dyno today, and I was well pleased with the results.
My engine builder told me their engine dynoed was conservative (642HP) and they were not kidding!! First pull 559, second 561 and third 559. Not bad for a small block on Pump Gas that Idles at 950 and will run all day long on in fifth gear at 2100rpm. Oh by the way this was with the small carburetor (QF 850) the 1050 made 12 more HP and more TQ throughout the entire RPM range on the engine dynoed! I am very happy with the results. Engine 461 SBF, Custom LSM solid roller, Super victor (dr J port work).
