I thought the smaller primaries and the 2-1/2" collectors would hurt me at the strip but the Dougs have really suprised me with the performance. I would like to try the ttis for the stepped primaries on my next 360 build.
Remember Chrysler Power magazine ? They were always doing performance/installation comparisons with after market heads, exhaust, HEADERS, carbs, cams, anything that claimed to do something better than what we had,,,,,,,helping the mopar world , and saving all of us lots of time and money, and aggravation. Not only doing a flow bench test or such, BUT actually installing the product on they're motor/car, and taking it to the track and doing a hands on... I still dig out those old Chrysler Power mags from time to time, and reference them......It seems like all the Mopar rags out there now are afraid to do this. It's all about the advertising bucks.
