AFR’s best right now i think is 320. there was a article in the november 2004 car craft. it was a big block vs. smallblock. they used a bbc454, and a sbc 454. both ran the same brand of heads . they tried to make all the variables the same. . guess which made more hp and torque. they said most likely due to higher port velocities of the small block. the mag is in front of me. stop over i’ll give it to ya --- _[View the full topic](https://forums.speedlife.net/t/350-or-383-sbc/187866)._
