Aftermarket block street strokers.

Hopefully some more time was spent tuning that. Those AFR numbers are “abort the pull” lean to me. Probably some more power there too.
We only made two pulls due to the AFR issue. I was just on the dyno to check for leaks and run in. The carb used was a 950 HP dyno carb and I am going to run sniper xflow fuel injection in the car and will do more testing in the car on a chassis dyno when the car is all together. I agree that there is more power once things get dialed in and I play with the timing a little.
