Best 1/4 mile combo's???

[greg schroeder]

My car was slower with the 427R as delivered before I spent a pile of money to change a few things listed. I believe the Superformance exhaust is the most restrictive part that I change, but the Pro-Systems carb also made the car come alive.

The video pass in my signature is starting off idle with a 1.7 60ft time, 10.7 @130.6 mph. The track had a nice hook with the drag radials. Note the car is rock solid and straight with an effortless pass. I did that twice in a row and then went home. Keep in mind each .1 sec off 60ft is good for about .2 at the end, so there's no need to thrash the launch. A realistic slightly aggressive start 1.5 60ft time would put the car in the low 10s, but there's not much point in being aggressive. MPH remains about the same either way. On motor only, no power adders, I believe the combination I have is favorable performance wise to most big blocks given the small block is less weight and generally makes more power per cubic inch.
