Best Intake for a 408

I have a 410 stroker in my car and I had an air gap intake and it made 390rwhp on the dyno. I changed cam to afew degrees bigger(from 238 @ 50 with 110 l/sep to a 241 @50 with a 112 l/sep) and changed to a Victor 340 manifold . It now made 425 rwhp but lost a bit of torque on the dyno but in real world driving (5 speed manual) I cannot notice any difference. I feel it is noticably quicker especially as when you just put your foot into it in second gear it just goes mad with wheelspin immediately to 6500rpm. Lets face it with a stroker 410 how much torque do you need in a 3000lb

I run a 11-1 plus 360 now on 93 octane.

What cam do you have now and what are you thinking about going to?

When you say maximize the 408, it leaves a lot of room for interpretation. Pretty soon you’ll have @RustyRatRod coming here and stating his famous line on cam size….

.750 roller

A little more clarity on a goal please.
The cars purpose is?
Is a 1/4 mile slip part of this chase?
How do you get away with 11-1 on 93. I ask because I want to as well. Engine specs, cooling system, vehicle weight, gearing, dynamic compression, etc.
