motor: 355 ci, ported/polished with matching intake, 11.9 pistons, cc306........the motor is rebuilt with all new parts.

3.42's, shift kit, 2600 stall...

here's the question: i dont know if i should get a 58mm throttle body. i've spent enough money on this car already, is the 58mm TB NEEDED? i mean, will my car suffocate if i dont get one? or will it run just fine? i mean, this isnt a 396...just a little 355

with my setup, how much power is the TB really worth...is it worth it at all to spend the money? i'm not worried about gaining 10hp...but i'll get one if it's more than that.

thanks in advance
