Also, a friend ran my engine combo for the Chevelle and it was way off and yes he did use the correct flow rates for my Edelbrock Performer RPM heads. Desktop Dyno 2000 showed 737hp@7000 & 650tq@5000. I've run my car on a chassis dyno and it made 461rwhp and 462rwtq. Given a 20% loss that's around 550hp.
