Wich nitrous flange do i need to use with my speed demon carb?

 

Also what is the purpose of antiballooning plates? do I need a t/c with them if I spray? is it a track safety thing? I cant find a 27 spline 3000 stall with lock up and anti ballooning plates

 

Square Bore 4150, I think thats what you are looking for. Not really sure about the torque converter. Probably depends on how much hp your running.

 

I plan on using eddelbrock nitrous kit, and the square bore kit is 697 vs 459 for others, are you 100% sure its a square bore?

 

Demons are square bore just like the holley carbs. Carbs like carters and Q-jets are spead bore.

 

those 27 spline transmissions are weaker, everyone pretty much swaps out to the later style 30 . i belive tci makes a 10" 3000 stall 27 spline for the v8 transmissions
i just got a 27 spline 10" 3,600-4,000 for my car from them though my converter has a diff crank pilot (smaller diam) then the v8 version.so u would have to take a look. if not there vigilante may make one.
though u would prolly be better off swaping out to the 30 spline trans.
and if ur going under 150 shot i dount u need the anti balloning plates

 

do you mean 150 shot and under, or under a 150 shot? I was going to get a 30 spline 3000 stall and a 30 spline 700r4(same trans you sold to robws6 with the l98/700r4 combo you sold him, but hes not pulling the t/c out any time soon, and i want my car done.. plus my 700r4 is rebuilt

 

150 and lower, if ur gonna buy a converter when u call up to order it just tell them what ur planning to do and how much nitrous ur gonna run.cause they would know best if ur gonna need the antiballoning plate or not
