not trying to take mellow approach i do not know cam specs yet the motor is being rebuilt right now, i will get all the specs when he is done, i am just trying to get info on converter hoping that at the very least i can get away with 2200 stall because of price difference compared to 2500, budget is running low due to everytime you try to build something there are always unexpected costs, as i stated above i am going to have a edlebrock alum performer intake with 600 or 650 4 barrel carb, with hooker headers, pertronix 2 ignitor distributer and flame thrower coil, with mild cam and was told it would be about 340HP, as far as cam specs and duration i simply dont know until i get info from builder, just hoping a 2200 stall will work due to money running out on project as i am on disibility and have limited funds. thanks
