TBI head swap to 180 AFR

[chris989]

Hello all,

1989 v2500 5.7 4l80 original build

I am on the fence with regards to swapping a pair of AFR 180cc heads and ditching the TBI swirl. My original build has been great but thinking of making an upgrade. The truck currently get 15+ on the highway,, ~13 around town and ~10+ towing. I don't want to mess that up swapping to a BBC but always looking for a little more torque.


Has anyone swapped about the swirl ports and seen again? was it the same?
I am not really interested in "vortec" heads,,, I would consider in aluminum any AFR, Trick flow, or edelbrock.

Yes i understand the value of a roller cam but for the price tag i would stroke the 5.7 first..

Thanks,

I've been on the fence with the same thing. I think the route I'm going to take is a roller cam swap first. I'm looking at the SUMMIT 8800 cam and go from there.
