Quote: What are the other time increments and speeds? It seems slow. How much is the driver tho? When does the acceleration peter out? What rpm are you launching and shifting at? What is the timing curve? To me, 38° may be a little too much timing. What springs are in the outboard carbs?
I know modern performance rebuilt, stock-part 383s that with decent tires and 3.23s will pull 100mph in the 1/4. Factory original or not, they can do it with the stock cam and a good tuner.
depending on gas 38* would be my start but 36* is good too. Yeah I failed to add what is your rpm launch, of course it's probably a little low because of your tires...You might want to roll out then hit it.
Best I could do with a 383 in a 69 Charger w/ 3.23's on radials was 14.10@101 but that was a very stout 509 cammed 383. 3.91's and slicks knocked me down to 13.28 same engine in a 68 dart and 4.56's went 12.18 w/ a terrrrible trans, but that's OT.
