I don't know if anyone has told you this but AP72 your a pretty helpful guy, thanks
It looks like I would have to implement a custom ground cam for this one. At least if i want to use a solid ft @230/230 dur. with an lsa of lets say around 107. (normal 280 magnum i believe is 110). If i changed to 1.6 rockers that would put lift at .512 which I think would be adequate.
At the bottom is a link to a set of 190cc aluminum vortec heads on ebay. As far as big port and aluminum these are all my budget will allow. If I don't get the go from you guys on them it will be summit racing vortecs. They are $580 for an assembled pair, lifts up to .520, and I will prolly take them apart and touch up the bowls just a little.
And hey my 400 only has 2 freeze plugs on the sides so I can tell people its a 355 with stock vortec heads
