14.45 with 12 sec combo... HELP

Yep and when it finally crosses the line at ful song, come back with an MPH number. That number is critical to determine your horsepower, which can ballpark your ET. No number is like being blind. Just try and hit the pot.

I have a little Hughes 232* cam that goes 7200 if /when I ask it to. Put some springs on yours, and let er buck. How you gonna go 12s @ 5500 on the limiter? Maybe with a bunch more cubes....You mighta gone faster/quicker with less gears!

Oops that mighta sounded condescending. Sorry.
When I check the crower cam 267-hdp comes out as pn31241, which is218/222@050 on 112LSA. Does that look right.
Isnt that about the same size as the old M/T,340 cam, that went mid 14s on street tires, back in the day?
My old combo, much like yours but with Hughes HE2330 cam(223intake,230ex)and a stick, went 106 with 3.55s,in 3rd gear around 6500@ 3650lbs, at 217m(712ft?). I was pretty happy with that....Your Duster is probably a good bit lighter.
I have yet to figure out how the cam people come up with those range numbers and how they play out in the real world.
