Old combo:915 heads with very mild back-yard port job, Venolia domed pistons, Howards aluminum rods,MP .590 flat tappet cam, Crane 1.5 rockers,Torker manifold, Holley 850 DP carb...

Changes made:Edelbrock Victor heads, Hughes 1.6 rockers, Edelbrock Victor 2886 intake, the above mentioned Comp Cams cam




My 2-cents:
1) Changing from a Torker to Victor 383 intake was a good idea
Victor 383 info sheet The attached comparison is a milder motor, but FYI.

2) The headers sound good.
3) It is likely the heads just don't flow a lot more than the 915's (~78cc ?). But they did show a gain OOTB.
4) That is a weird cam choice, but I just don't know.
