Very disappointed with my 347 dyno!

8850, i have read the last couple of your posts and watched that vid you put up here of your car, sounded killer. back to the point though, the cobra intake you are running is designed to run out of steam at 5500rpm in a 302, the extra inches just lower that rpm range, even if it has been majorly hogged out, the long runners are way out of sync with your cam. i say ditch the intake first...i have heard good things about the new TFS intakes and edelbrocks are proven pieces. the victor might be to large for you, but the only way to know for sure is to check and see, i would think it will be an improvement over the cobra though. MM&FF just tested the victor on a solid roller'd, high comp 347 and they said the intake's potential couldnt be realized even on that motor, so you might want to look at the Perf. RPM first. just an idea though. i would worry about the intake before you get the long tubes if you are on a tight budget. just my opinion though. sorry this is so long, nick
