Just curious.... on what are you basing your HP number? I'd guess you have the J heads ported some to get to 385....I ask because if you want more and are starting at a true 385, then you're gonna want to step
- Indy with 2.02" (Indy's are iron) and Edelbrock Performers are the next likely step up with rocker's similar to what you have.
- Then heads like the W series (iron) and Edelbrock Victors.
You can look at the Hughes site and see a lot of different flow tables for different SBM heads to get an idea of where these are in the 'pecking order' of flow. This is for comparison.... I would not take the HP number presented there as gospel.
