no need to delete.... It is relevant, but to help understand the time you ran we needed to know what it's in (for weight) and gears, etc. 5800 lbs Maxi Van or a 2800 lbs early A, big difference. LOL. As I stated earlier, 74 mph is slow for that combo, unless you are doing a 450 ft one tire fire. What I'm saying is you are not getting the potential your combo has currently, so why throw parts at it? Tune it.
