I have a 79 camaro, 350, carter afb, performer intake, long tube headers stock cam, 2.24" true duals, close ratio 4 speed with 308 posi. i have 225/65r14 tires. so at 50 im at about 3000rpm someone said i would get better performance with 373. Can any one tell me what would happen if i go from 308 to 373?
