I am torn about what to do. I built a new combo over the winter, it's a 496 BBC w/1.80 glide 4.33 gear in a 3400lb 10" tire car. The thing made good power on the dyno, peak tq was 704 at 5700 rpm and peak hp was 864 at 7000. My converter is a 9" and I have always wondered if I should be running an 8. It is NA. The thing flashed at 5000 last year behind a much "tamer" combo with more conservative heads and cam. This one is going 4800-5100 behind the new engine. Obviously it is a little lazy.out of the hole (okay a lot lazy) so I definitely have to do something. Should I go with a new 8" deal or stick with the 9" and have it reworked?
