A few questions....first, all intakes fit Gen V or do you need to specify according to year?

I am thinking of changing intakes, exhaust, and carbs for now and cams next fall.

Not looking for anything crazy, just want to get them up over 400hp each.

So what intakes? is the real question. Edelbrock performer? Air gap? RPM? I don't think I will need a single plane intake.

Cams will be comp 11-236-4.....cb m 270h-12
.544 .547
duration @ .050 226 236

Carbs....holley 850?

All intakes the same 9.8 4150 style i would run world products merlin single plane works great they have a marine one with brass inserts in water ports i have used them on stock type 454/502 engines ran well

That intake wouldn't be wanting to make power completely out of the range of my motors? WOT is currently only 4900-5000 rpm.
