Update! I ended up swapping in a used 5.9 magnum engine, with a reground camshaft and ported the heads in my backyard! I didn’t have so much time to tune it with carb and timing curve because they were closing the drag strip in a month. But regardless I was pretty happy, was hoping for high 7s but all good.
When I first started, running 9.5 @72mph 2.180 60ft 6.236 330
Now I ran a 8.3 @82Mph 1.876 60 Ft 5.259 330
