Next mod (2 months from now) 450R CARB! And she will torque even more..
Keep stock gearing
AWSOME BUILD! And it should be reliable..
From what I hear you dont need hd studs, thought if I was you I would change my low end bearings just to be safe. Thought ask around you probably will be able to get away with it.. Make sure there is no play and mesure the end play.. Make sure its up to spec. Finally all this is not to hard to do just do it by the book and STAY ORGANIZED.
One last thing, dont waist your money on a rev box or a 450r carb or the sparks ignition. I am not saying those things are pointless but they are mostly ment for the end.. The carb will for sure make a big enough diff but 150.. Spend that on a new piston.. Rev box will change your timing curve but it wont give you much more power. Then sure it revs higher... But you should also spend that money on a hot cam.. lol... Then the sparks timing key is realy cheep but might not work to well with 11:1 comp.. lol I think im going 2 look into that..
Take care
