I wanted to try the Victor std. port heads on this 400 with a cam change and bump in compression to see how much power we can get out of a somewhat budget type build.

What I didn't know is that Edelbrock has changed their Victor heads! A new heart shaped chamber and smaller more restrictive intake bowls.
I was worried about them performing well since the intake ports are down on flow compared to the older castings.
I was very happy to see a pretty decent amount of power for a pump gas budget deal. No porting was done, on anything.

New spec's are:
New Victor heads, OOTB with our valve job and small chamber cut.
Compression at 10.6:1.
Hughes 1.7 rockers (VERY nice rockers by the way!!).
Tried both the rpm intake, and victor intake which made the best avg. power over the rpm!
Holley TRUE Ultra 950HP
Still used the 1 7/8 TTI headers, same bottom end as prior but changed the cam to a custom grind: 255-260 @ .050 on a 110lca and .648/.638 gross lift.
And all the power came in at a very respectable rpm IMO.

I would highly recommend some porting on these heads to make the best of them, but like I said it was a budget type build on pump gas.

Still, if you look at the TQ and HP curves it's making really good avg. power AND torque.
