That 414 is putting down some crazy numbers two run 11.1s on motor like high 500s (like 580) and then the cam must be perfect for the nitrous I have never seen perfect numbers off nitrous with a big cam it is usually off 20-30 horsepower at the wheels.So two put down 780 hp is awsome expecially threw that huge stall and trans.Make me kind of wonder if he is not sparying more than a 200 or just talking the truck up a little. Nice truck though.
the N/A runs were made on a aggressive motor tune on race gas. acctually it was 750 on nitrous on the maf tune, now its speed density open loop, have not dynoed it yet but it sure feels like another 50 or so stronger. thats only one kit 200 shot on that run, and a best of 10.0x at 140mph with crappy worn out tires
but stay tuned for the second kit that i'm going to be installing
, should be able to see speeds in the 150's or very close to it

What cam are you using? Also that truck sounds mean as hell. But my real question is if i wanted to use a 100 shot but i dont want to build the motor just for nitrous because I know later on its going to be boosted what cam do you recommend?

Flaco- You might have said this before, but I'm lazy and don't want to look it up!!....what size headers are you running? I was going to build a 370 for boost, but have decided to do a nitrous 408. I'm affraid my 1 3/4 LT's might choke it quite a bit. Just wondering what you are using. Those rear D-10's are still lookin good by the way!

Yeah speed density is the only way to go I think.The throttle response is alot better two.That is awsome times I bet your 60fts are crazy! Are you leaving off of a trans-brake or footbrake?

im agreeing with nxpres03 your times dont match up to what your saying according to the youtube clock you ran a 13-14 second 1/4 im not convinced till i see some slips. Any one that would run that hard on the dyno would have that printout up on the refriderator dont get me wrong its a fast truck but lets see that slips
