C16 and a 200 shot....TIMING?????LOOK
I dont like to try and make ET predictions but I have a good feeling about next year.

Take another 200lbs out
add 50+cfm of head and intake flow.
lastly another bullet in the chamber.

You just replied to a 4 year and 8 month old thread.
You must of went in the archives for this one.
Pull 6 degrees on the 200 to start. the c16 in the tank is only adding 200 hp worth of fuel to the mix. if his motor makes 400 its a 33% mix. You still need to pull the correct timing. also put some tr9's in there for the first few runs and get a good reading on them. get your timing mark just off the tip and the fuel line down the bottom of the procelin. then go 1 step warmer on the plug and take out 1 degree of timming from your final numebr where the timming mark was correct. and get the fuel /timming back to the right spot. compair mph with the 2 finished tunes and if there the same go with the colder plug tune.
Remember, it's your engine and money. The guy on the internet forum isn't going to help you out when you burn up some pistons.
TR6 is too hot. I'd go two steps colder on the plug(NGK V-Power would be an 8). Also, get the non-projected tip. Notice on the TR6 how the porcelin sticks out a good bit passed the threads? You don't want that with a decent nitrous shot on the car.
