Gearing new car
505 BBC, 12:1, Dart 340 heads, Dart Intake, Demon 1295, 150 shot of spray .750 lift cam, 1.76 glide (May switch to a 1.80) 32x14.5 in a 2900lb car. Trying to get it set up for quarter mile and was wondering what gear everyone suggest ?

oh gawd !!!...that 150hp shot changes everything....
He will need to be given two sets ups..one for the all motor and one for the NOS..You can't have the best of both worlds.....
there is not enough information in My opinion to give a NOS gear set up.
lobe sep on cam, ring gap,tire roll out size, converter,NOS spread, Nos fuel pressure, external fuel supply system, or one big pump, method of timing retard,......just getting started !
this can turn down so many rabbit holes when you throw NOS in the Mix.

As far as the nitrous I am not worried about that rit now due to the fact it will not be used rite now cause its a new car and just want to get the feel for it before I get into that. I set the car up for a 2 fuel system with a bg280 pump. As far as that goes I am hearing more and more people just say run straight up motor so now the gears are turning again!

understand Big CI engines with exotic Big chief heads etc...Can handle 200hp shot and down and be a little more forgiving..in other words you can cheat it up a little on the cam etc...as long as you stay small on the NOS hit...with that said your 505ci is not considered a large ci engine, your also running conventional heads so you really need to treat it as a large small block IMO, When it comes to NOS..Again ( jmo)
If I were you since you mentioned N/T I assume you are setting up some grudge races...right ??? If so I would concentrate on being all HP and put more effort on losing weight and learning to conceal the weight loss and swear its 3800lbs no mater what !!!!!!! 8)
