You should be o.k. with the #8 as long as you put some good fuel in there with it. Nothing less then 116, I'd opt for torco 118 if it is available. Make sure you pull enough timing too, 2 degrees per 50 hp, especially to start!
And make sure you shut the car off at the end of the track, pull over as fast as possible and pull some plugs and check them. If you're doing this size hit without a directport, definately pull #5 and #7, as they tend to run the leanest. I'd probably run the car to the 1/8th and shut it off the first run, beter safe then sorry.

Will try that out for sure. Im going to upgrade this year to a direct port but wanted to try the 2 stage nx kit out. I found c16 race fuel from a buddy of mine that owns a gas station. Is there anyway to keep the #5 AND #7 from leaning out. Any certain way to turn the Shark nozzles I know for you smart a$$ point it toward the center of the intake lol. Mine are mounted behind the maf. thanks

As far as tunning goes if you put a tr7 vs a tr8 does this effect you tunning / air fuel tables. Basically what I mean if the car is tunned on a tr7 then will it not run as good on a tr8 thanks

have a 408 with 2 stages a 100 and a 200 shot and have tr6s in it that is what thay put in the car win thay were tuning it. I dont spray both stages that much but if i put TR7s in will the car run the same? i did have the TR8s in... it was fouling the plugs out win tuning so we put the TR6s back in it. If you don't drive the car much and just let it sit there and run it will start to foul out the plugs now with the Tr6s so will it foul out the TR7s faster? it has a 257/266 cam in it and was not EZ to tune.
I have had the 6's turn into blow torches with a 285 shot, so no more extended tip plugs for me (the 7's and up are not extended tipped).

It will run safer, and faster longer with the colder plugs!
