454 or 383

[son69]

Hello, i have a dellema. I need a new motor for my 69 camaro. i was going to build a nice 383, when my engine builder suggested he could do a 454 bb for about the same money. I realize i'll have to change some things to get the motor in my car, but now having trouble deciding. I will be driving it ao the street so drivability and reliablity will be a big factor, but i also want something that will put me in my seat when i put my foot down. I have a th-350 with a 12 bolt and 3.55 gears and a eaton posi. What do you recommend?????? pros and cons of both... Thanks in advance
