Chime in with suggested cam spec's 408 build

Thanks guys, all good info and appreciate it, Justin, the block has a partial hardblock fill to try and combat block flex, I really like Mikes roller lifters and intend on buying a set and had asked him about a cam but he only gave me a price. He maybe a little pissed at me cause I had intended on having him build an engine for me however our south pacific peso exchange rate tanked and made the build cost prohibitive sadly. it took a $10K build to $15K overnight! thats my EFI right there.
Michael, heads are long valve W2's with 1.6's, will be doing our best for lift.

if anything else pops into your thoughs I'm keen to hear it, thanks again
