Well I just realized after 5 years that my carb is not opening up the secondaries all the way, its a holley DP. The secondary butterflys are 1/4 of an inch from being truely vertical.

I fixed it but the track just got rained out for the 2nd week in the row(I think we are up to 22 days of rain in the past 30 days), so instead of real racing, i'm doing the next best thing, bench racing!

How much hp/et do you think i would gain from correcting this problem? My father seems to think it won't make any difference but I'm inclinced to believe there has to be some. What do you guys think? Currently the combo is running 13.7s @101.

both my HP hollly carbs are like that. i found a place in one one vizards books about quadrajets that says vertical may not be the best for fuel distribution. there was a post here a while bake where one of the members here runs his at 15*. not sure why tough. Dave
