Bill,
Assuming you have stock heads I would use for example:
The 390gt/428cj cam, duration 206-220 at .050, or
The Crower 270hdp, dur is 210-220 at .050
or
The Summit or PAW generic cam with 204-214 dur at .050
With stock heads and that kinda small performer intake I wouldnt go bigger than the above. Best to use new springs & 1-piece retainers but you might sneak by with stock springs if you dont go over 5000 which will work fine as a shift point.
You'll probably make 335hp with manifolds, maybe 350hp with headers, but not 400.
But the Summit or PAW cam&lifters you could do for under $100, it sounds like you're on a budget. |
