I knew the cam was too large when i built this engine, but i literally built this engine from parts that were left overs from friends, i originally started with a 9inch converter, but it only would stall 2500, then i broke the trans and when i put it back in i used a 2000 cause its all i had at the time, i really love this camshaft so if i need to upgrade around it to maximize it i will, with the right intake and converter i really wont need the nitrous.. at least thats what im hoping
