If I would be you Xoliex, I would consider by going with the hardened input shaft. If your engine is now in 650 ft-lbs range with some help of a juice your torque will definitely break the 800 lb-ft, probably closer to 900 lb-ft. The torque increase with the nitrous is usually bigger than the hp that you're making with the juice. Every engine reacts of course in it's own way, but with your size / hp engine it usually goes like 150 hp nitrous makes 200 lb-ft of torque. My friends 532 cid Ford was dynoed a month ago, it boosted the torque from n/a 638 ft-lbs to 939 ft-lbs with 250 shot of nitrous oxide so the increase was 301 ft-lbs with 250 NOS.
When you got the small shot of nitrous, you usually want a bigger shot of nitrous for the next time
You'll be happy with the Victor Jr intake, it'll boost the higher rpm and it looks better than the Torker II
For the tranny, I would built as good C6 that I can afford because you know the thrill... soon you're planning to hit the 1000 hp, so go big now and you'll be saving money in the future. My 2 cents.
i have a correct bbf c6 in the backyard and i originaly just wanted to build that. i was going to have a company give me all the parts, and have them machine all the parts on the inside of the trans for rollerization but that was going to cost 1900. for another 500 they were just going to give me a core and they will dyno it. thats 500 well spent and not to mention with just the parts, i'll have to send it to them, have them ship it back and then have somebod else assemble for me for 500. and since i opted not to do the hardened input shaft it was 250 less. guys in the 460 forum says the stock input shaft is good to 800ft tq which i'm only at 650 and with even nitrous i'll barely hit 800. i think when i recam the motor, i think my HP will finally be higher than my TQ.
