Ok I hope I have the big C10 dialed in now.
I'm guessing it at curb=3750 + passengers=300 lb since my buddy's 1964 c10 weighed 3900 with a 350-4bbl.
For the engine/trans in the video the Gonkulator says
2.42 60ft
11.77 at 60.5 1/8 mile
18.59 at 70.5 1/4 mile
11.6 0-60mph with a really slow 2-3 shift in there.
With a bone stock 292 single exhaust, Gonkulator says
2.44 60ft
12.25 at 57.3 1/8 mi
19.50 at 67.1 1/4 mi
15.3 0-60mph
So its almost a second faster already
With the new engine and that glossy Ford Blue paint I bet it picks up another 2.2 seconds (1 second for the trans and shifting, 1 second for the engine, and another 0.2 sec faster for the Ford Blue). Oh, I forgot the Bling - maybe faster yet!
