New heart

thats a good start but if its all going into an early a, then get out the checkbook. you will need a new radiator, new driveshaft, bigger rear end, new motor mounts, new throttle setup, new shifter, new kickdown setup, and probably will want to get disc brakes too. if going to discs and/or 8.25 rear end then count on new BBP wheels/tires as well.
sorry if i burst your bubble but the related parts to a 360 swap add up fast! ask me how i know haha!
anyway good luck with it right now you are ahead of the game.
