Stay with the 40 until you can get the 39. 10.5-10.9 is alittle rich. but all of the wet kits I have put on my cars have always been about that rich when I used the jets that came with the kit. The 39 should put you in the sweet spot of 11.5-11.9.

thanks guys, just for what its worth. im running a 03 cobra sunday night. he says he has 800 hp, he has a aftermarket blower 24 psi, alky injection and a 150 shot. i really dont know what he all has but im going to run him from a 45 roll. i have big cam/heads, 440 whp na and im shooting the 240 on it. roughly 640 whp , calculating out to 775 flywheel hp. ill let you know how it goes. i will have a vid 
hope u have some good shoes on the back. your gonna need them.
why a 45 punch. that is not an optimum mph for your ride. assuming you have an auto.
if he hooks say bye bye.

Id run the tires if i was you. you will get yanked if your spinning and he hooks. also if he set the MPH its most likely to his advantage. Dry nitrous works magic on heatsoaked blowers. his 150shot will bang out more power than the jets are set for just by the gains of coolin the air charge.
Also find a cameraman whos worth his weight in video quality. not worth draggin 150+lbs along if your going to shoot video of his lap or the dash.
